Free and open source program pivotal to
taking advantage of multicore hardware

Free and
open source program will roughly positively be a approach to

The organiser of Multicore World 2014 Conference
at Auckland’s AUT on 25 and 26 February, says computer
engineers are commencement to get to grips with writing
programs to effectively hoop many cores on one chip
(multicore), that dramatically increases computing
processing power.

“But there’s many different
approaches to how to yield these instructions, and we’ve
assembled a world-class operation of speakers to outline these
software advances, that so distant haven’t matched the
massive hardware increases by computer-chip
manufacturers,” says Erdody.

“For IT managers, CTOs
CIOs, mechanism engineers and developers and anyone with even
a spirit of seductiveness in where computing is heading, this
conference will be invaluable.”

Among a speakers is
Associate Professor Manuel Chakravarty of a University of
New South Wales who will illustrate how a ‘Accelerate’
open source horizon delivers a rival multicore

The Lead Data Technologist during Germany’s
codecentric AG, Pavlo Baron, will explain since their approach
is to use Java Virtual Machine (JVM) as a approach to understanding with
multiple millions of events per second in a multicore

New Zealand’s Catalyst IT, who are also one
of a conference’s sponsors, will have a Cloud Engineer
Ricardo Rocha report some of a poignant shifts that

Building a cloud ecosystem with open source software

Tuesday, May 28th, 2013

Mention a difference “open source” to IT pros meddlesome in adopting cloud computing, and their
ears expected will perk up. Open source program offers a resolution to a businessman lock-in concerns
many enterprises have with committing to a cloud platform. And cloud platforms like a OpenStack
, that fosters ‘coopitition’ among ostensible competitors in a prohibited cloud computing
market, give companies a choice to build interoperable open source clouds. But what options do
enterprises have when seeking open source PaaS?

Cédric Thomas, CEO of OW2
Cédric Thomas,
CEO of OW2

SearchCloudComputing spoke with Cédric Thomas, arch executive officer of OW2, a Paris-based, eccentric village focused on formulating a code
base of open source program for cloud computing. Similar to Apache and a OpenStack Foundation,
OW2 concentrates on infrastructure program as good as a collection to develop, muster and manage
applications for approximately 100 projects over a 60-member village that’s 22,000 developers

How does OW2 differ from Apache, OpenStack and other open source cloud platforms?
Cédric Thomas: We were founded out of Europe; a members are especially corporations, organizations
and universities rather than individuals, that is a box for Apache. Other than that, we don’t
differentiate in terms of technology.

We recently had meetings with OpenStack
and satisfied there was no foe during all between OW2 and OpenStack, since all OW2 does
is indeed a covering above that. OpenStack concentrates on a Infrastructure as a Service (IaaS)
layer with a compute, network and storage functionalities. Everything OW2 does targets the
Platform as a Service (PaaS) covering — a applications or a concentration platforms for a cloud.
All a cloud projects now have OpenStack as a anxiety for a growth platform.

We are implementing on a possess infrastructure since we horde services for a members. We are
implementing an OpenStack cloud height so that a plan and exam growth will [run] on
OpenStack. You can consider of OW2 as bringing value to a OpenStack ecosystem. We didn’t wish to
find ourselves in foe with them because, in a open source world, there is no reason to
compete. We wish to reuse or enhance in areas that are not lonesome by a open source friends.

OpenStack talks about a thought of ‘coopitition,’ that joins competitors together to foster
cloud computing projects. What are a hurdles with this coopitition approach?
Thomas: Up until 2010, open source was in foe opposite exclusive software. Every
category that has been developed, invested, marketed, explored, sold, upheld or confirmed was
done by exclusive vendors who eventually sole in a open source world. The approach it was … open
source program customarily copied exclusive software. You can even contend it started with GNU; it’s
not singular and it was defined, by comparison, with something that already existed.

Something altered in 2010. We satisfied cloud computing was not customarily a selling breakthrough and decided
to position OW2 to cloud computing. We satisfied open source was, with cloud computing, racing —
not following — exclusive software. That open
source innovation
was pushing creation in cloud computing. So, open source was a best way
to collaboratively innovate with cloud technology. With open source, a simple attribute is
defined by a open source license, that creates open source a really easy approach to cooperate,
collaborate and innovate — even if vendors are competitors.

We support a handful of cloud projects and a vendors are also intensity competitors. The whole
open source transformation will broach technologies that will not be products. That’s important. we think
open source will assistance companies strech a turn of record or state of a art with technology,
and afterwards they can conclude a offering. The genuine plea is that open source will broach a
half-baked product or a product that’s customarily 80% or 90% finished, afterwards vendors will finish them on a
commercial basis. That’s what we’re doing with some of a projects, and that’s what function with

On a PaaS front, are we competing with exclusive solutions?
Thomas: At a Infrastructure
as a Service
(IaaS) level, all a technologies are flattering most identified. And it’s all a
matter of customarily productizing and removing it to industry-grade offerings. And that helps companies
deploy workloads to cloud computing platforms.

Now what’s during interest and a genuine plea is to rise a cloud-oriented information systems
for companies and certain services. These cloud-oriented information systems will precedence social
applications, data, resources and services — some of these are inside a craving and some of
them are outward a enterprise. So, cloud-oriented information systems will be totally hybrid. And
that’s what PaaS is about: To assistance companies and CIOs rise a subsequent era of information
systems. What we customarily call PaaS, during a really simplest form, is where this creation will take
place. We rise a middleware
that uses resources supposing by opposite technologies of opposite companies.

Some criticisms of OpenStack are that it hasn’t been prepared for full prolongation or critical
updates occur a bit slower than a village would like. Is that partial of a problem with having
so many competing vendors operative together?
Thomas: You’re looking during a potion half empty. In 2010, there was zero during all. There were
three people; now [OpenStack] organizes events with 3,000 people in reduction than 3 years. You
can’t go any faster than that. That is bringing and converting a lot of expertise, a lot of
feedback. That’s what happens in open source partnership projects; vendors all contribute, though at
some point, they all demeanour for their possess interests. It’s an attention in a making.

Since we feel outrageous changes can occur in dual years with open source, what do we see
happening in a subsequent dual years?
Thomas: There will be many some-more OpenStack distributions out there. IaaS will somehow be more
commoditized. It will use village off-the-shelf [COTS] platforms. we consider a hosting industry
will be consolidated; there will be a tiny series of vast hosters heading a market. In North
America, it will be Rackspace, Amazon Web Services and Google; in Europe, any nation will develop
national hosters to understanding with information correspondence issues. Each nation will have a handful of national
hosting companies utterly mostly tranquil by a vast telcos.

[These vendors] will offer services and applications and combined value. OpenCloudware, for example,
develops a technologies to conduct lifecycle applications over a cloud. We’re not articulate about
infrastructure. It addresses a needs of a concentration and looks ceiling in a information
stack. The concentration is on a applications and all a production we need to conduct them.

The new era of applications will have a cloud-oriented philosophy. It’s not an
application that will precedence databases or estimate cycles; these new apps will be
service-oriented and will call on Web services supposing by third-party computing companies.
Everything will have to be standardized. These applications will also be deployed opposite servers
and mobile devices. Servers will need to hoop a estimate mandate of mobile devices. This
is a new design and new methodologies in program engineering as well.

IBM bets on open cloud

Tuesday, March 5th, 2013

IBM has thrown a weight behind open cloud standards, announcing that all destiny cloud services and program would be formed on “open cloud architecture”. As a initial step a association currently denounced a new private cloud tool, SmartCloud Orchestrator, formed on a open source OpenStack project.

“History has shown that open source and standards are hugely profitable to finish business and are a vital matter for innovation,” IBM comparison vice-president of software, Robert LeBlanc, pronounced in a statement.

“Just as standards and open source revolutionized a Web and Linux, they will also have a extensive impact on cloud computing. IBM has been during a forefront of championing standards and open source for years and we are doing it again for cloud computing.

“The leader here will be customers, who will not find themselves sealed into any one businessman — though be giveaway to select a best height formed on a best set of capabilities that accommodate that needs.”

IBM assimilated the OpenStack Foundation as a top-tier Platinum member in Apr final year.

OpenStack is a collection of open source program for building open and private clouds. It can be used possibly by providers who wish to broach infrastructure as a use to business or enterprises that wish a private cloud for on-demand, self-service provisioning of discriminate services for departments.

The roots of a project, that launched mid-2010, distortion in partnership between NASA and Rackspace.

OVirt vs. RHEV: Are they interchangeable?

Monday, February 25th, 2013

What are a primary differences between RHEV 3.1 and oVirt 3.1? Can we use a two

Sander outpost Vugt: Both oVirt 3.1 and RHEV 3.1 capacitate server virtualization. In fact, Red
Hat formed RHEV on a oVirt software. Nevertheless, a dual do have some pivotal differences that
dictate how we should muster each.

Red Hat Inc. grown oVirt as a Web-based, open source information core virtualization platform. A
oVirt setup
requires a hypervisor and a government server. Red Hat Enterprise Virtualization
(RHEV), on a other hand, is a server virtualization height where a underlying KVM hypervisor
is integrated into a Linux kernel.

Red Hat expelled a collection
of open source program as oVirt
before going blurb with it as RHEV with a purpose of
testing facilities in a community. As a result, oVirt contains facilities that RHEV will never
include simply since it did not accommodate expectations.

Another cause in a oVirt vs. RHEV contention is that distinct RHEV 3.1, oVirt 3.1 has no
enterprise-level support. Furthermore, RHEV
requires Red Hat Enterprise Linux
as horde handling system, though oVirt could theoretically be
made accessible for any platform. At a moment, however, oVirt 3.1 usually runs on Fedora.

Bottom line: You can configure an enterprise-scale virtualization sourroundings with possibly oVirt

Controlling skyrocketing costs of cloud computing

Thursday, November 29th, 2012

When operative with a cloud installation, costs can simply ascend — possibly we build a
private cloud or adopt open cloud computing services. Though enterprises cause in initial
purchasing costs, they mostly disremember costs compared with building and handling clouds, as well
as ongoing upkeep they need from IT teams.

There are ways to keep a costs of cloud computing down, though with exclusive software,
in-house growth and open source options, a right choice is not always clear. Though there is
no one-size-fits-all answer for determining cloud costs, with a right information, an enterprise
can select an choice that works.

The cost of in-house cloud growth contra purchasing

To investigate a costs that arise from building and

    – Margie Semilof, Editorial Director

managing a
, we need to consider about it from dual angles: first, a upfront and monthly costs of
software, and second, a costs of profitable employees. As an example, let’s review dual options for
managing a private cloud.

Option one is to compensate a monthly price to squeeze reward government tools, such as those RightScale
offers. Fees for these government collection can run anywhere from $500 to $1,000 or some-more per month,
depending on a package.

Enterprises have another option: capacitate their possess IT teams to use several application
programming interfaces
(APIs) to write their possess tools, so avoiding a vendor’s fees. But
sidestepping a cost of a reward government apparatus doesn’t meant an in-house choice is free.

An IT group competence spend, for example, 200 hours building a tools. Depending on a hourly rate
of IT employees, a man-hours concerned could run a association $10,000 or even $100,000. In a short
term it competence seem like you’re removing a understanding by carrying in-house staff rise a tools, though after
factoring in those costs with a ongoing costs of progressing a tools, enterprises competence not be
saving income after all. Additionally, those in-house government collection competence not have all the
capabilities of premium
on a market.

When determining if we should rise in-house tools, ask yourself, “Are we in a business of
building software?” For an craving with small knowledge constructing a possess software, costs
can simply spin out of control. For example, a nursing association motionless a in-house IT group would
roll out a possess inner software. The problem was that upper-level government knew zero about
how to conduct a program team; it simply wasn’t their business. After dual years of struggling
through a growth process, a group was incompetent to broach a final product, and a company
lost hundreds of thousands of dollars on squandered growth efforts. If a association had examined
its possess capabilities before embarking on this project, it would have dynamic that a most
cost-effective choice would have been to squeeze an existent product or sinecure an outward organisation to
build a software.

Factoring in a open source cloud option

Though open
source cloud options
are technically “free,” that doesn’t meant they won’t cost an enterprise.
Any software, including open source, can emanate issues for untrained or fresh staff, so
it’s critical to cause in support costs.

Scalr is a renouned cloud government height that includes an open
source option
. It offers a set of monthly plans, any with a possess pricing structure, in
addition to a “free” open source version. Enterprises can possibly compensate for a program and the
included support group or use in-house IT admins to install, configure and say a system. With
the second option, training costs and man-hours paid can mostly overcome any agreed-upon and
expected monthly charges.

Clearly, zero is truly free. You contingency cause in not usually a costs of a products and
support plans, though also a time and bid it will cost your association to build and say the
systems. Weigh a costs of monthly skeleton opposite a costs of progressing an in-house support

Finally, cause in a highlight involved. You competence find it is truly reduction costly to select open
source software
with an in-house support team. But be certain your staff is unequivocally prepared for
it. Or will we need to sinecure some-more employees?

In a end, a cheapest choice competence not be a many desirable. Controlling cloud
computing costs
is no elementary matter, though it can be done, supposing we cause in all the
components adult front — and comprehend what you’re removing in to.

Vendor-supported open source program unpacked

Thursday, November 15th, 2012

The value of vendor-supported open source program was a concentration of a row contention during ITWeb and Linux Warehouse’s Virtual Data Centres Forum, hold during Montecasino on Wednesday.

The aim of a contention was to empty a vendor-supported open source program materialisation and fact what opportunities this kind of program creates for practical information centres.

“Open source is everywhere, generally in information centres. And a genuine value of vendor-supported open source program is to residence some of a intensity business risks that were formerly not addressed,” pronounced Muggie outpost Staden, MD and CEO of Obsidian.

According to Linux Warehouse MD Jan-Jan outpost der Vyver, vendors give a association “peace of mind” since they have a technical trust and skills to take caring of problems for a organization and safeguard they do not occur again. “That turn and abyss of support is unequivocally what we are shopping when we select to go with vendor-supported open source software,” Van der Vyver said, adding that a skills that accompany this kind of support are invaluable. “All of these guys have specific training modules and programmes available, that expands a trust of your workforce.”

This view was common by all a panellists. “I consider one of a many vicious things is a support. With open source products, a products are typically grown in a community, and what an open source businessman does is take that risk out of a village and supports it in a long-term way,” pronounced Sven Lesicnik, MD of Linux System Dynamics (LSD).

“With village support, we will many expected have to filter by 200 answers to your question, though with businessman support, they give we profitable answers in a discerning and fit way,” pronounced Franco Austin, business growth manager for focus solutions during Dimension Data. Austin alike a value of this support to a roadmap, in that a businessman can beam a business in a right direction.

“Managing a information centre effectively is critical, generally in a practical environment. In a virtualised environment, regulating vendor-supported open source products gives we so most precedence where we can impute behind to a businessman for advice,” pronounced Austin.

Another advantage that was highlighted was a reduced costs compared with vendor-supported open source software. “What craving open source vendors do is they make a program enterprise-ready and take a risk out of that indication and afterwards yield it to business regulating any information centre,” pronounced Lesicnik, adding that this is cheaper than going with a normal exclusive program vendor, who has to possess a formula from start to finish.

For Van der Wyver, regulating vendor-supported open source program for mission-critical systems is essential; many companies are realising this, and as a result, are relocating in this direction. He adds that they are doing so for several reasons, one of that is security. “On those occasions when things go wrong, it is vicious to have a subsidy of a businessman with experts who will assistance to solve a problem so that a risk to your business significantly decreases,” pronounced Van der Vyver. “The energy of open source companies is that, if they find a bug and they repair it, they put those commentary behind into a village so that others can entrance it,” Van Staden added.

The panellists also discussed a pitfalls of businessman lock-in and a following costs of migrating to another vendor. “You need to consider about what a cost is of removing off a certain technology. With open source, emigration is a lot simpler,” pronounced Van Staden. Using open source program simplifies a emigration from one businessman to another, as there is no genuine reason to retrain support staff, according to Austin.

Case study

During a forum, Philip Booysen, a technical dilettante during FNB, discussed his practice with vendor-supported open source program while operative during a bank.

“FNB thrives on embracing innovation,” he said, and as his dialect focuses on a core IT infrastructure within a bank, they are always looking for improved solutions to make banking some-more efficient. “We trust in a advantages of vendor-supported open source – a reliability, a support, a open pattern and a security,” pronounced Booysen.

According to Booysen, his group promotes a serve adoption of open source program within a bank, adding that it is vicious for FNB to sight a staff to be efficient in doing this kind of software.

“The open source expostulate during FNB has been phenomenal. Our online banking and mobile banking are all abounding interjection to open source and Linux,” pronounced Booysen. Although a bank still has a really extrinsic environment, combing all from mainframes to Microsoft, Booysen believes a biggest reason for a success of open source during FNB is that a leaders during a bank entirely support this software.

Like a panellists, Booysen stressed that implementing vendor-supported open source program is needed when traffic with business-critical solutions. “We apparently have utterly a few business-critical solutions that make a bank work, and these solutions need a arguable and open architecture,” he said. He also echoed a panellists’ sentiments about lock-in, mentioning a significance of avoiding businessman lock-in by not relying on a singular vendor.

“I trust that each product is singular and that we need to tackle them in opposite ways. Open source program and Linux gives me a leisure to unleash my creativity in sequence to pattern next-level IT, now.”

    Dad builds video baby monitor

    Friday, November 9th, 2012

    Rupert Plumridge with his baby monitorRupert Plumridge can keep an eye on his children from his kitchen TV.

    Video baby monitors are among a latest gadgets gift assent of mind to concerned new parents, though with a cost tab of adult to £200, they are over a strech of many families on a budget.

    That’s because when his daughter Lily was born, patron family manager Rupert Plumridge from Bristol motionless to use Android devices, a night-vision webcam and open source platforms (free software) to build his own.

    Two and a half years after (plus a new further to a family in a form of five-month-old Dominic) Mr Plumridge, a self-confessed “geek” in his gangling time, thinks he has polished his video guard complement – and he says it cost him usually £50.

    “It’s all giveaway detached from a camera itself,” he said.

    Continue reading a categorical story

    What is open source?

    The creators of open source program concede others to entrance to their products’ formula to concede them to inspect and cgange a contents.

    However, they competence still practice egghead skill rights over it – for instance ominous an blending duplicate of their work being sole for profit.

    As a outcome some firms that rise open source projects assign for appendage services rather than a program itself.

    The California-based Open Source Initiative has published a commonly-accepted clarification of a tenure on a site.

    It says program licences should not distinguish opposite any organisation or margin of endeavour, and should be technology-neutral – in other difference not restricting a product to any singular mechanism height or character of interface.

    The best famous examples of open source program embody Android and other Linux-based handling systems; a Mozilla Firefox browser; a Gimp graphics editor; and a WordPress blog software.

    The webcam he chose can be changed around remote control, has night prophesy and a microphone.

    Mr Plumridge has video feeds from both his children’s bedrooms that he can perspective around wi-fi from his Android smartphone, tablet, laptop and kitchen TV.

    He used a giveaway chronicle of an app called IP Cam Viewer for a inscription and TV, and a giveaway media actor called VLC by a organisation called VideoLAN on a laptop.

    “I can perspective it on my phone anywhere in a universe if we have a mobile network connection,” he said.

    “I was in London a integrate of days ago, and we watched my son and daughter going to sleep.”

    He says that a password-protected wi-fi he has during home is sufficient confidence to forestall others from tuning in to observe his sleeping infants.


    For now his children do not seem to be phased by a tiny webcam intense in their bedrooms during night.

    “It looks like a intense eye,” he admitted.

    “It could be a bit freaky though Lily doesn’t mind. It reassures her, she knows ma and daddy are looking out for her.

    “Some people competence consider it’s a bit ‘Big Brothery’ though it’s some-more usually to know they’re OK,” pronounced Mr Plumridge.

    “If Lily tells us to spin it off, we’ll spin it off. It’s down to her when we take it away.”

    Mr Plumridge has fraudulent adult his guard for friends as a foster and has blogged about how he did it, though he doesn’t intend to enter a market.

    “I’m a large follower in open-source software, I’m happy to share a knowledge,” he said.

    “Why assign for something that’s giveaway anyway?”

    Commercial cameras

    Security camera organisation Y-Cam is one of a latest entrants to that marketplace after rising BabyPing, a commercially video guard complement for inscription computers and smartphones, 6 months ago.

    TV shade and tabletThe device also works on a inscription computer.

    “We were saying relatives shopping a cameras and bettering them to make into baby monitors, and we thought, ‘that’s a good idea’,” pronounced orator James Hunt.

    When Y-Cam arch executive Devin Chawda had a baby he did a same thing himself.

    “He pronounced ‘It’s good though it’s blank some features’ – so he started operative with a product group to emanate this baby monitor,” pronounced Mr Hunt.

    Mr Hunt says BabyPing’s £165 cost includes invisible infrared record so a night prophesy camera can't be seen by a baby, and some program they have grown themselves called Smartfilter, that blocks out crackling and feedback noises.

    So distant it has valid some-more renouned in a US than a UK, pronounced Mr Hunt, and is now usually accessible for Apple products, nonetheless an Android chronicle is due out in 2013.

    Cost caution

    Anne Longfield, arch executive of inhabitant children’s gift 4Children, urged counsel about investing in dear gadgets in a hothouse if income is tight.

    “The large instance of where record is building fast is around baby monitors,” she told a BBC.

    “Traditionally a guard would tell relatives when a baby wakes up. Now we have heartbeat monitors and videos.

    “You need to take a settlement on either it’s positively essential, is it unequivocally going to assistance your baby?

    “If we have a whole bank of record around we there’s a risk we won’t be means to relax.”

    Three questions that can make any open source cloud businessman squirm

    Sunday, September 30th, 2012

    The tenure “open cloud” isn’t only a new, subordinate cloud computing buzzword, it’s quick becoming
    a religion. So, during that church do we urge — a church of OpenStack,
    the church of CloudStack,
    the church of Eucalyptus
    or do we attend services during a residence of another open source cloud player?

    There are a few reasons a cloud
    is relocating in a open source direction. First, we adore a judgment of operative with
    technology that is not gratified to a singular vendor. Second, we have a (typically unleveraged)
    potential to expostulate change in record to improved accommodate a requirements. Finally, a cost of open
    source cloud
    is typically right, with many of this record costing small to nothing.

    The earthy phenomenon of open cloud record comes in a form of distributions.
    Distributions are instances of open cloud software, typically with some additional value-added
    features. In a universe of cloud computing, this is typically program compulsory to emanate a private,
    public or hybrid cloud. However, distributions could also be cloud government stacks, security,
    use-based accounting or other components that make adult a cloud.

    There are, however, downsides to open cloud record that we should always cruise in your
    technology preference process. For example, we need to know a loyal cost of deploying open
    source program contra blurb offerings.

    In many instances, organizations name open source before they know their loyal business
    and record requirements. The use of open cloud program could indeed cost we some-more than a
    commercial chronicle since open cloud might not be a good fit in certain cases.

    This is where a aspect of sacrament comes into this technology. Enterprises mostly make leaps of
    faith that challenge sound logic.

    So there are a few questions we need to ask your open cloud record provider to be sure
    you’re not blindly following a wrong cloud religion. And these questions might make your open
    source cloud provider a bit uncomfortable.

    Does a use of this open cloud record pledge portability?

    If your cloud businessman is guileless with you, a answer is going to be a organisation “No.” The notion
    that applications and information localized on one chronicle of an open cloud will pier A-to-A to another
    distribution of a same customary is a bit
    of scholarship fiction
    right now. Current cloud standards are fragmented, creation portability among
    cloud providers difficult. Eventually, this problem will be resolved, though how shortly we’ll get there
    is still unknown.

    Will this cloud product be around in 5 years?

    The scold answer is, “Who knows?” Even if we speak to a incomparable cloud players with gobs of
    money, a fact of a matter is this marketplace is quick growing. Venture collateral dollars are being
    spent quick and furiously to start these open cloud companies. Sooner or later, things will

    Smaller companies with successful products will overlay into incomparable companies or go away
    altogether. In some cases, products incomparable companies yield will be deemed unprofitable and will
    be cancelled or pushed out to a open domain. This is an emanate on both a open and commercial
    sides of a market, though a open source side is flourishing some-more rapidly.

    Will we be means to support in pushing a cloud standard?

    The scold answer is, “If we have adequate income and time.” For a many part, technology
    providers — not finish users — expostulate standards. The existence is these organizations are groups of
    loosely joined record companies driven together to yield a plain evidence for regulating their
    technology initial and regulating a customary second.

    If you’re looking to get into a design-by-committee mix, you’ll be acquire with open arms in
    the open source community. However, you’ll have to have adequate poke in a diversion to expostulate the
    changes you’re seeking as good as a giveaway time indispensable to follow a record provider around from
    meeting to meeting. The incomparable we are and a some-more income we spend mostly gives we some-more contend in the

    OpenStack Folsom Adds Network Automation, Block Storage and Hyper-V Support – SYS

    Thursday, September 27th, 2012



    OpenStack® Folsom, a sixth recover of a open source cloud computing
    platform, saw a 65 percent boost in contributors, as good as the
    further of Networking and Block Storage services, architected in line
    with a OpenStack truth of pluggability and extensibility. While
    work was underway to settle a new OpenStack Foundation, the
    abounding village once again delivered a recover on-time and with all
    designed essential features.

    OpenStack Folsom automates pools of compute, storage and networking
    resources, now including rising Software Defined Networking (SDN)
    solutions around OpenStack Networking plug-ins, to build private and public
    cloud infrastructures but businessman lock-in. OpenStack Networking
    now includes plug-in support for Open vSwitch, a Ryu open source
    network doing system, customary Linux overpass networking and
    blurb solutions from Cisco, Nicira, and NEC, with others in
    development. Written by some-more than 330 contributors, a Folsom release
    facilities a continued concentration on fortitude and extensibility, while adding
    substantial new facilities like Networking, Block Storage and Hyper-V
    support. The village also done poignant swell with localization
    efforts, introducing a new interpretation horizon for a software,
    user-facing guides and documentation.

    With some-more than 300,000 program downloads, support from vital Linux
    distributions like Debian, Fedora, Red Hat, SUSE, and Ubuntu, and
    deployments announced around a world, OpenStack continues to make a
    tellurian impact with a Folsom release. Two of a largest OpenStack
    open clouds, HP and Rackspace, are putting Folsom into production,
    charity users a choice they design when standardizing on OpenStack as
    their open cloud platform.

    New Features in OpenStack Core Projects

    While fortitude and manageability were pivotal themes of a Folsom release,
    contributors also combined 185 new facilities opposite compute, storage and

    • OpenStack Compute (code-name Nova)With a focus
      on palliate of use, performance, and security, a latest recover of
      OpenStack Compute creates it easier for operators to configure large
      pools of practical machines. A new “config drive” capability stores
      network pattern information, expelling a need for DHCP, and
      a new “host aggregation” underline places workloads into a best pools
      of resources for a job, such as GPU clusters for HPC work.
      Performance and confidence enhancements capacitate users to display unique
      facilities of a CPUs powering their cloud, including support for
      Trusted Computing, that relies on hardware to establish a cloud
      computing environment’s state. A cross-company Hyper-V group shaped to
      reintroduce and urge support for a hypervisor.
    • OpenStack Object Storage (code-name Swift) Among
      many operational enhancements, operators can now bond OpenStack
      Object Storage to a statsd server and accept hundreds of real-time
      metrics about their cluster to assistance with troubleshooting, diagnostics,
      day-to-day operational issues, and long-term ability management. To
      urge performance, clusters with high write mandate or large
      quantities of stored objects can now take advantage of solid-state
      drives (SSDs) for storing metadata but incurring a high overhead
      in hoop space. Additionally, a ability to place information in cluster
      locations that are “as singular as possible,” creates it easier to deploy
      tiny clusters and provides softened coherence for all clusters when
      doing hardware failure.
    • OpenStack Block Storage (code-name Cinder) – The first
      full recover of OpenStack Block Storage implements advanced,
      extensible retard and volume storage capabilities, while still
      ancillary formerly deployed OpenStack Volumes. Previously a
      sub-component of OpenStack Compute, a Block Storage capabilities of
      OpenStack have been promoted to a full plan with a dedicated
      growth group that will boost a rate of creation as
      the OpenStack growth village grows.
    • OpenStack Networking (code-name Quantum) –
      An modernized network automation height that empowers users to choose
      their back-end technology, OpenStack Networking includes support for
      Open vSwitch, a Ryu open source network doing system, standard
      Linux overpass networking and blurb solutions from Cisco, Nicira,
      and NEC around a plug-in architecture. Additionally, a recover includes
      poignant updates to control Layer 2 networking, IP address
      management, API quotas, notifications, prolongation support for Layer 3
      forwarding, Secure Network Address Translation (SNAT), and floating
      IPs. An integrated API process horizon allows network control during the
      reside turn or a admin-only turn to be tangible regulating a OpenStack
      Identity service, depending on an Enterprise or Service Provider’s
    • OpenStack Dashboard (code-name Horizon) The
      second full recover of OpenStack Dashboard brings usability
      improvements in rising Compute instances, operative Object Storage
      resources, and doing OpenStack projects and users. Other feature
      advances embody support for open and private picture uploads and
      government of modernized networks. End users will conclude better
      cross-browser support, timezone support, energetic share displays,
      softened blunder handling, and opening improvements.
    • OpenStack Identity (code-name Keystone) The
      second full recover of OpenStack Identity brings softened support for
      Public Key Infrastructure (PKI) authentication and improved
      formation and government opposite OpenStack services.
    • OpenStack Image Service (code-name Glance) – There were
      vital advancements in usability and functionality to a Image
      Service, including a new API, a new customer library, new replication
      options for increasing opening and confidence improvements reaching
      from a customer to a picture storage system.

    “The Folsom recover cycle brought larger majority to a program and
    processes, as OpenStack developers constructed a stable, feature-rich
    update,” pronounced Jonathan Bryce, executive executive of a OpenStack
    Foundation. “Hitting all of a pivotal targets with this recover is proof
    a transition to a Foundation did not delayed us down. By preserving our
    meritocratic technical governance structure, we had even some-more developers
    contributing and are relocating during a faster rate than ever before, while
    also being unwavering of a village of users relying on a software.”

    OpenStack Summit Fall 2012

    The subsequent OpenStack Summit will take place Oct 15-18, in San Diego
    and brings together gifted open source developers, business leaders
    and authorised experts in one venue. The OpenStack Summit has grown into
    a premier open cloud eventuality of a year with scarcely 1,000 OpenStack
    contributors, users and ecosystem members approaching to share box studies
    and best practices, cover topics of vital seductiveness for open
    communities, and establish a roadmap for a subsequent release. Headline
    sponsors embody Canonical, HP, Nebula and Rackspace, and a eventuality will
    underline presentations from OpenStack users including CERN, DreamHost,
    eBay, HP, Living Social, Rackspace, Sina and WebEx. See a full agenda

    An open dialog on open source cloud

    Monday, May 21st, 2012

    source cloud software
    has a share of advantages and downsides. The thought of a license-free
    option can be engaging to budget-conscious IT departments looking to make their initial pierce in the
    cloud space, as can a guarantee of no businessman lock-in. But a do-it-yourself
    nature of open source
    can be a vital waste to smaller IT shops that miss a dedicated
    technical growth staff indispensable to build and conduct an open source cloud architecture. sat down with attention researcher Bill
    to plead a market, what companies of all sizes should cruise when looking to
    build an open source cloud and that vendors have a many change during a moment.

    What are a advantages of regulating open source cloud?
    Bill Claybrook:
    is a approach to furnish program and discharge it. It’s only an doing paradigm.
    Open source means no permit fees; we can do with it flattering much

      When we register, my group of editors will also send we alerts about public, private and hybrid cloud computing as good as other associated technologies.

      Margie Semilof, Editorial Director

    what we wish within a few
    rules, including placement rules, settled in a open source permit description.

    There are many open source cloud licenses and any generally has a few incompatible manners on what
    you can do with a open source code. If you’re doing loyal open source, clarification you’re downloading
    it and regulating it, afterwards we need technical people who are means of indeed ancillary a open
    source code. If we don’t have that, afterwards if we wish to use open source we competence have to compensate a
    third celebration for support. This cuts into a cost assets that we design from a use of open
    source cloud.

    In other cases, if you’re deploying a vast series of servers, like eBay, Amazon, Bank of
    America and other vast financial institutions do, with 10,000 to 15,000 servers, and have the
    technical imagination available, open source creates a lot of sense. If we had to buy proprietary
    cloud-type program for any one of those servers, afterwards a cost of chartering could be substantial.
    If we have a lot of servers, and you’re perplexing to emanate a cloud around those servers by
    virtualizing them first, afterwards open source is a unequivocally good approach to go — generally with

    Additionally, a chartering is not as difficult as it is for sealed source offerings like Oracle
    or generally Microsoft. With loyal open source, we get chartering mobility, that means everything
    these days in cloud
    . In cloud environments — even if you’re only doing virtualization on servers in your
    lab — we wish to pierce applications [workloads] from server to server, yet if we don’t have a
    license for a aim server, we can’t do it. With loyal open source, we have a lot some-more freedom
    to move
    applications from cloud to cloud
    . That is a outrageous advantage and saves we a lot of money.

    You can also rise a complement some-more quickly. If you’re regulating open source program that’s easily
    accessible, we can exercise formula and exam it yet spending any income on licensing. You can get
    the open source, download it and rise a indication of a program complement we wish to test. As a
    result of this, we finish adult saving time, that translates into a cost assets as well. The ways in
    which open source program is grown and distributed allows we to get a plan underneath way
    faster and during reduce cost.

    What are a drawbacks to going with open source?
    The biggest obstacle of open source is a miss of support. You have to have
    technical people around to support it and do a growth around it. If you’re regulating open source
    to emanate a complement or platform, you’re substantially going to have to confederate a series of other open
    source plan codes. If we collect all open source to build a private cloud, someone in your team
    will need to confederate all a components and make certain they work.

    On a contrary, if we go buy VMware,
    the association will substantially give me a whole garland of products — during a unequivocally high cost — that will all
    work together. But afterwards we can get sealed into VMware products. Some people also feel the
    frequency of releases for open source program is too mostly and there are too many of them. Other
    developers trust this is an advantage since we get new facilities quicker.

    Would a cost of carrying means in-house growth imagination be reduction than chartering costs
    for blurb cloud software?
    If we have a lot of servers, afterwards we unequivocally need technical people who can support
    [open source]. Large financial institutions mostly ride toward open source since they can
    customize a code. Companies that have a capability to technically support and cgange open
    source to prove their possess needs should be means to understanding with it. If we are building a cloud
    around 5 open source projects, for example, afterwards we unequivocally need to have people who work and
    contribute privately on those projects. That way, if we have facilities that we wish to use,
    your people can work within a horizon of a open source plan group to presumably get those
    features enclosed in a mainline code.

    If you’re regulating formula from a unequivocally vast open source project, you’ll substantially find a lot of
    support for a plan on a Web. If you’re regulating a middle to tiny open source plan in your
    cloud, afterwards we competence have a lot of difficulty anticipating that support. A association competence also spin to open
    source since it can be used to perform some specific business need. If we find open source
    software that’s unequivocally strategically critical to your business case, afterwards that’s another reason to
    go that route. For example, there are open source program companies with products that will manage
    all of your hypervisors so we can discharge open and private clouds from one workstation.

    Which are some of a vital open source cloud
    There are a few. Many cloud vendors are proprietary, yet there are a series of
    others that are open source. Eucalyptus
    is an open source association with products formed on open source code. With Eucalyptus
    release 3, a whole height is open source. The association creates a income by offered annual
    subscriptions that embody blurb plug-ins and technical support. You can build a private
    cloud; it supports most of a Amazon
    Elastic Compute Cloud
    [EC2] application
    programming interface
    [API]. If we have an sourroundings that’s all VMware, we can go in and
    slap Eucalyptus IaaS [Infrastructure as a Service] on tip of a VMware virtualized server
    installation and make it into a private cloud. And Eucalyptus has scarcely doubled a workforce in
    the final year.

    Then if we wish to go to OpenStack,
    which is unequivocally a project, it’s arrange of a heavenly of a open source world. OpenStack is not
    really oriented toward a tiny and middle companies — even yet it’s open source. It’s more
    geared toward a craving and use providers who have a technical capabilities to understanding with
    the product. There’s no support for it, unless we wish to buy it from partners such as Rackspace.
    You can also get some assistance from a OpenStack plan members themselves. And afterwards there’s Ubuntu,
    which is a Canonical Ltd. open source handling system, that has also been bundled with

    Another open source cloud businessman that’s flattering cold is Abiquo, that has a government product
    that’s a singular console to conduct private clouds and open clouds. It’s hypervisor-agnostic and
    it’s a unequivocally cold open source product. All of these open source products offer blurb versions
    or blurb plug-ins to a open source plan code. The sealed source, blurb versions
    generally have facilities that are not enclosed in a open source versions. If a new underline comes
    out that users unequivocally want, some vendors will back-port that underline into an comparison chronicle of the
    open source program that they are distributing.

    What about cloud interoperability issues?
    That’s kind of interesting. My clarification of interoperability is relocating applications
    from one sourroundings (cloud) to another. Most cloud environments — if we have a Terremark cloud, or
    Amazon cloud or Savvis cloud — all of those environments were implemented by opposite people
    using opposite hypervisors, opposite handling systems, opposite database systems, etc. And when
    you have an focus that we wish to pierce from your information center, or maybe from your private
    cloud, to a open cloud, it competence not work yet a lot of effort.

    The problem is that if we go with Microsoft opposite a house we competence increase
    interoperability and afterwards we kind of get locked
    into their software
    . Secondly, anywhere we wish to pierce an focus to [from a
    Microsoft-based cloud, for example], we roughly have to pierce it to another Microsoft-based cloud or
    you have other issues around relocating a application. Right now, interoperability is roughly a wish
    [rather than a reality].

    So what other costs can we design with an open source cloud product?
    If you’re going to do open source in a reasonable way, we unequivocally need to have some
    developers who are operative roughly full time on that project. If we wish to get certain features
    into a code, your approach in is by a developers. An combined cost would be carrying dual or three
    developers, partial time, during least, operative on a project.

    Another cost with open source is that we don’t get all my program from one place. If we go to
    Eucalyptus, they could substantially give me all a program we need. However, if I’m piecing together
    my open source software, as many companies do, afterwards someone has to confederate all this stuff, put it
    together, make certain it works, exam it, all that. If we have a imagination to put it together
    component by component, you’ll also have to confederate it and afterwards exam it. You’ll save some money
    on chartering and we competence get improved scalability and even opening with open source software, but
    you’ll also spend income [on developers].

    Open source is good, yet we have to be careful. You’re jumping off into a outrageous project. If you
    don’t have any genuine imagination in-house, we improved sinecure someone to assistance we or buy commercial.
