Why OpenStack Is Losing Momentum: A Seven‑Year Retrospective

1. Decline in Community Activity

Mailing‑list traffic for OpenStack peaked in 2016 and has been decreasing steadily since. The number of full‑time developers is estimated at fewer than 20, roughly 10 % of the peak workforce.

2. Lack of Sustainable Business Model

Most OpenStack vendors have been unable to generate profitable operations. The OpenStack Foundation has been the primary financial beneficiary, unlike Linux (Red Hat) or Hadoop ecosystems where multiple companies achieved IPOs or sustained revenue streams. Consequently, the market has contracted and exit opportunities for startups have diminished.

3. Ineffective Technical Committee (TC)

The OpenStack Foundation created a Technical Committee to guide the project's technical direction. After the 2015 “big‑tent” expansion, the TC became largely inactive. When Mirantis withdrew in 2016, many projects lost maintainers and the TC did not intervene, leading to a growing number of dormant projects.

4. Limited Enterprise Value

In China, the primary OpenStack customers are government agencies and state‑owned enterprises that use the platform for self‑innovation rather than competitive advantage. Compared with VMware, OpenStack offers minimal resource‑saving or efficiency benefits, and the separation of resource creators and users prevents true self‑service models.

5. Competition from Kubernetes and PaaS

While Docker containers do not directly threaten OpenStack, the maturity of Kubernetes and modern PaaS platforms reduces the perceived need for an IaaS layer. Many users assume PaaS must run on top of IaaS, yet PaaS can be deployed directly on bare metal, further diminishing OpenStack’s relevance.

6. Technical Foundations Remain Viable

The core OpenStack services—Nova (compute), Cinder (block storage), Neutron (networking), and others—are still functional and stable. Containerized deployment tools such as Kolla can provision OpenStack with integrated logging (EFK stack) and monitoring (Prometheus). Kolla’s community has merged Prometheus exporters, enabling observability without additional tooling. Upgrade and downgrade paths are supported; for example, Neutron can be reverted to an earlier version to maintain SDN compatibility.

7. Outlook

Even with technical improvements, the ecosystem’s decline is driven by business and governance challenges rather than technical shortcomings. Without a viable revenue model and effective community management, OpenStack is likely to continue a gradual descent, with future deployments possibly limited to niche or legacy environments.
