New York-based media hulk Bloomberg deployed OpenStack cloud on one of a biggest private
networks in a world, with some 200 points of participation globally. But it encountered problems
“below and above a stack,” according to Pravir Chandra, arch record officer and security
architect for a company, who spoke in a keynote display here.
Below a stack, there was a matter of environment adult rarely accessible databases, application
messaging in a form of RabbitMQ, and Inktank’s Ceph storage. Above a stack, there were log
aggregation and metrics for monitoring hardware, for that a association used a Graphite open
“We had to solve a lot of these problems ourselves,” Chandra said. The association puts a Chef
cookbooks on GitHub for
others to learn from.
Samsung SDS, one of a largest information and communication record providers in Asia, has
tested OpenStack for a private
cloud to broach mobile applications to customers. It expects to have an OpenStack cloud in
production by July. The association began with the
Diablo release dual years ago and found it really unstable, according to Kirk Kim, executive at
Samsung SDS in Korea. Subsequent releases have improved, though they compulsory such customizations as
the ability to auto-boot volumes from a storage area network, a Nova backup service, and network
metering regulating IP tables.
Samsung SDS also found it required to move in multi-cloud
management program from RightScale to camber a private and open cloud environments.
“OpenStack is rarely stretchable and configurable though also, generally in a early days, formidable and
error-prone,” Kim said.
Kim also overwhelmed on a problem of upgrading
between releases, that in some cases have necessitated re-architecting and rebuilding
components of a OpenStack cloud platform.
The BestBuy.com online sell website is now wholly formed on OpenStack after a yearlong
process of analysis and development. The idea of this plan was to revoke a volume of
It was also meant to cut costs, according to Steve Eastham, executive of Web design for the
company. An inner investigate of IT costs suggested an normal cost of $20,000 per managed virtual
machine (VM), and a company’s possess peculiarity declaration routine was costing it $500,000 per major
release, he said.
Now a Web skill has about 500 instances active in a OpenStack cloud on average, for a
cost of $91,000 per shelve of hardware. But as other OpenStack users have found, customization was
One of a arch examples of this for BestBuy.com was a switch divided from Gluster, an open source
distributed record complement now owned by Red Hat Inc., to Ceph storage. Recoveries of VM images, some
as vast as 200 GB each, took too prolonged with a prior storage system.
BestBuy.com also grown a tradition Chef government apparatus called Ginsu, a plug-in that replaces
the knife-OpenStack utility, and is some-more firmly integrated with a Nova discriminate application
programming interface. It uses a collection of monitoring tools, including Sensu, Collectd,
Graphite, and a tradition dashboard formed on Ruby Sinatra. This final application caused a problem when all
of BestBuy.com’s 40 growth teams attempted to record in during once. “It was kind of a DDOS-it-yourself
situation,” Eastham said.
The association still runs a Essex
release of OpenStack, though skeleton to ascent to Grizzly,
the latest release, in a entrance months.
In general, automation is a requirement for OpenStack cloud environments rather than a
nice-to-have, according to Jim O’Neill, arch information officer during Cambridge, Mass.-based HubSpot
Inc., a selling Software-as-a-Service firm. This was something a association did for itself using
both Chef and Puppet.
O’Neill likes a DIY inlet of OpenStack. “If something doesn’t work a approach we like, we open
it up, repair what’s wrong and minister it behind to a community,” he said.
