OpenStack Cloud
OpenStack is a community of open source
developers, participating organizations and users
who are building and running the open source cloud
operating system.
“OpenStack is an Infrastructure as a service which is known
as a Cloud Operating System, that takes resources such as
compute, storage, network, virtualization technologies and
controls those resources at a data center level”
“OpenStack’s basic requirement: “Cloud must be simple
to implement and massively scalable”

Why OpenStack
•Control and Flexibility. Open source platform means you’re never locked
to a proprietary vendor, and modular design can integrate with legacy or
third-party technologies to meet your business needs.
•Industry Standard. More than 60 leading companies from over a dozen
countries are participating in OpenStack, including Cisco, Citrix, Dell, Intel
and Microsoft, and new OpenStack clouds are coming online across the
globe.
•Proven Software. Run the same software that today powers some of the
largest public and private clouds in the world.
•Compatible and Connected. Compatibility with public OpenStack clouds
means enterprises are prepared for the future—making it easy to migrate
data and applications to public clouds when conditions are right—based on
security policies, economics, and other key business criteria.
