OpenStack Tutorials + Education Channel

OpenStack is at the core of our Infrastructure as a Service product, featuring hosted private cloud. We also use OpenStack to provide IT services to our own staff. As both active users of OpenStack and the first to create on demand hosted private cloud on OpenStack, we want to share our experiences with OpenStack. You can find more information in our Flex Metal Cloud Product Guide as well.
