OpenStack is a collection of projects for implementing infrastructure as a service (IaaS) and supports features like scalability, multi-tenancy, and automation. Key projects under OpenStack include Nova for computing, Swift for object storage, and Cinder for block storage, among others. The document also covers how to contribute to OpenStack through coding, documentation, and community participation.
