OpenStack aims to be the ubiquitous open source cloud computing platform that can meet the needs of both public and private clouds regardless of size through simplicity and scalability. In three years, OpenStack has expanded beyond compute and object storage to include networking, storage and shared services. It has public clouds in more cities than Amazon and major private cloud users like Best Buy, Bloomberg and PayPal. OpenStack has over 1,000 developers from major IT companies and is the center of cloud innovation.
