openstack运维手册
OpenStack enables you to build an Infrastructure as a Service (IaaS) cloud. If you are looking to build a cloud with the resources you have, OpenStack is an excellent choice. It's built from open source, and is designed to run on commodity hardware. In fact, many operators build an initial proofofconcept OpenStack cloud by scrounging together whatever used servers and networking gear that they can get their hands on. OpenStack was also designed for scalability, so you can easily add new compute and storage resources to grow yo ur cloud over time. Organizations such as HP and Rackspace have built massive public clouds on top of OpenStack.
