OpenStack

OpenStack is the most widely deployed open-source cloud infrastructure platform, providing IaaS capabilities including compute (Nova), networking (Neutron), block storage (Cinder), object storage (Swift), and identity management (Keystone). The platform is used by thousands of organizations worldwide to build and operate private and public clouds. Developed collaboratively by a global community under the Open Infrastructure Foundation, OpenStack gives organizations the ability to build AWS-like cloud capabilities on their own hardware. Major deployments include CERN, Walmart, and numerous telecommunications providers. OpenStack's modular architecture allows organizations to deploy only the components they need, and the platform integrates with popular tools like Kubernetes, Terraform, and Ansible for comprehensive infrastructure management.
