"To produce the ubiquitous Open Source cloud computing platform that will meet the needs of public and private cloud providers regardless of size, by being simple to

implement and massively scalable."

Mission Statement

Why OpenStack?

‣ Control. Open source, no vendor lock in. Apache 2 license.

‣ Flexibility. Modular design integrates legacy and third party technologies.

‣ Emerging Industry Standard. More than 180 technology industry leaders backing it and major public clouds built on OpenStack. 

‣ Proven. Originally built for scale and redundancy at NASA and Rackspace. More than 100 large-scale deployments worldwide.

‣ Compatible and Connected. Enables portability.
