OpenStack is a cloud operating system that simplifies the deployment and management of virtual machines or containers in a scalable and highly available way. It operates on pools of compute resources (physical or virtual servers) and provides an intelligent scheduling mechanism to select appropriate hosts, and to build or migrate VMs.
OpenStack allows an easier management of virtual images and provides a centralized way of creating and managing software-defined networks. It integrates well with a variety of external and internal projects in order to deliver user and service authentication. OpenStack modular design allows adding and removing services as needed where a minimal production deployment may consist of as few as two projects an image and compute service.
The following diagram shows the ever-growing list of OpenStack projects and the interaction between them...
