What Is OpenStack?
OpenStack is an open-source cloud computing platform for building and managing public and private clouds. It provides infrastructure-as-a-service (IaaS) capabilities similar to AWS, allowing organizations to run their own cloud infrastructure on commodity hardware.
Key Features
OpenStack consists of modular components: Nova (compute), Swift (object storage), Cinder (block storage), Neutron (networking), Keystone (identity), Glance (image service), and Heat (orchestration). Organizations deploy the components they need.
The platform manages pools of compute, storage, and networking resources through APIs and dashboards. It supports virtual machines, bare metal provisioning, and container orchestration. Horizon provides a web-based management dashboard.
Who Uses OpenStack
Telecommunications companies, research institutions, government agencies, and large enterprises that need cloud infrastructure without vendor lock-in. Major deployments include AT&T, CERN, Walmart, and China Mobile.
Pricing
OpenStack is free and open source. Costs come from hardware, operations, and optional commercial distributions from vendors like Red Hat, Canonical, or Mirantis that provide support and simplified deployment.
