OpenStack

"We expected to see a performance impact because of virtualization, however it was considerably smaller than we expected for many scientific apps. The first major pain point that we felt was the quality and scalability of cloud software stack."

"We decided to run OpenStack to help keep costs low, provide elasticity and help scale to thousands of VMs. Our immediate goals were to keep applications up and running, develop a large scale infrastructure with commodity servers and transform our infrastructure offering to a building block base.”

“As we examined the various initiatives we’d have underway in our cloud, which would include the intermingling of physical and virtual loads as well as complex network configurations, we knew that the flexibility inherent in OpenStack would prove powerful enough to support our objectives. With OpenStack we have the ability to customize the platform and maintain significant control over our destiny.”
