OpenStack is an open-source Infrastructure-as-a-Service (IaaS) platform for building private and hybrid clouds with modular services for compute, networking, storage, identity, and orchestration. It provides a flexible, scalable foundation for cloud infrastructure with multi-tenant isolation and self-service provisioning.
OpenStack is governed by the OpenInfra Foundation (formerly OpenStack Foundation) and developed by a global community of contributors and enterprises.
