OpenStack in 2026: what the open-source cloud platform does, how its services fit together, real deployment costs, and how it compares to AWS and VMware.
OpenStack is a modular, open-source cloud operating system that turns pools of physical compute, storage, and networking hardware into a self-service Infrastructure-as-a-Service (IaaS) cloud. Rather than shipping as one monolithic product, it is a collection of independent but interoperable services that administrators combine based on what capabilities they need.
Originally created in 2010 by Rackspace and NASA, OpenStack is now stewarded by the OpenInfra Foundation, a nonprofit that became part of the Linux Foundation in 2025. Thousands of individual contributors and hundreds of member organizations, including major cloud vendors, telecoms, and research institutions, continue to develop the project on a roughly twice-yearly release cadence.
At its core, OpenStack provides compute orchestration through Nova, software-defined networking through Neutron, and both block and object storage through Cinder and Swift. Keystone unifies identity and authentication across every service, while Glance manages virtual machine images and Horizon offers a web-based dashboard for administrators and tenants alike.
Beyond the core, optional services extend OpenStack into bare-metal provisioning (Ironic), orchestration and auto-scaling (Heat), container-native workloads, and telecom-grade networking for NFV use cases. This a-la-carte architecture is what lets a small research lab run a minimal deployment while a telecom operator runs a massive multi-region cloud on the same underlying platform.
OpenStack itself carries no license cost; the software is free to download, deploy, and modify under the Apache 2.0 license. The real cost of running OpenStack comes from hardware, staff time, and optional commercial support.
Most organizations either self-host and self-support OpenStack with in-house engineers, or purchase a supported distribution or managed-OpenStack offering from vendors such as Red Hat, Canonical, Mirantis, or VEXXHOST, whose pricing is typically custom and quoted per deployment size and support tier.
Yes. OpenStack's source code is free under the Apache 2.0 license. Costs come from the hardware you run it on and any optional commercial support or managed distribution you purchase.
OpenStack is governed by the OpenInfra Foundation, which became part of the Linux Foundation in March 2025. Development is driven by a global community of individual contributors and member companies.
No. OpenStack is an IaaS platform that manages virtual machines, storage, and networking. Kubernetes orchestrates containers. The two are often deployed together, with OpenStack providing the underlying infrastructure for a Kubernetes cluster.
OpenStack powers infrastructure at telecoms (for NFV and 5G core networks), research organizations such as CERN, public sector agencies, and large enterprises that need a self-operated, AWS-like private cloud.
VMware is a proprietary, license-based virtualization and private cloud suite, while OpenStack is open source and free to license. OpenStack generally requires more in-house expertise but avoids VMware's licensing costs and lock-in.
Yes. Vendors including Red Hat, Canonical, Mirantis, VEXXHOST, and Rackspace offer supported distributions and managed OpenStack services with custom pricing.
OpenStack's core services are written primarily in Python, with REST APIs used for inter-service and external communication.
