Key Concepts to Understand
OpenStack is the open-source cloud infrastructure platform that underlies a significant portion of non-hyperscaler public cloud globally, including offerings from Deutsche Telekom (Open Telekom Cloud), OVHcloud's Public Cloud, Citycloud, and numerous national and regional providers. It provides the same fundamental cloud capabilities as the hyperscalers, compute, block storage, object storage, networking, and identity, through standardized APIs. For enterprises, the practical significance is API portability: tools and automation built against OpenStack APIs work across any compliant provider, reducing the re-engineering cost of changing providers or running across multiple simultaneously.
How It Works
OpenStack public clouds expose their capabilities through standard REST APIs, including EC2-compatible endpoints on many providers that allow AWS tooling to work with minimal modification. Compute resources (Nova), networking (Neutron), block storage (Cinder), object storage (Swift), and identity (Keystone) are the core services available across most providers. Heat provides orchestration. The Horizon dashboard provides a web interface, though most enterprise usage goes through API or infrastructure-as-code tooling. Terraform's OpenStack provider supports most OpenStack clouds, making it the standard infrastructure-as-code tool for enterprises running on OpenStack-based providers.
Things You Need to Know
The enterprise experience on OpenStack public cloud depends almost entirely on which provider is being used. A well-operated OpenStack public cloud from a major telecommunications company is a fundamentally different experience from a small regional provider running the same software. Enterprises should evaluate providers on their SLA commitments, support quality, compliance certifications, managed service availability, and operational track record rather than on OpenStack compliance alone. The platform creates the possibility of portability; the provider determines the actual quality of the experience.
Key Capabilities
What openstack Brings to the Table
API Portability Across Providers
Workloads built on OpenStack APIs are portable across any compliant provider, reducing lock-in and enabling multi-provider strategies without re-engineering.
Sovereign and National Cloud Access
OpenStack underpins numerous sovereign and national cloud offerings, providing enterprises access to compliant infrastructure from providers in their own regulatory jurisdiction.
Terraform and IaC Compatibility
Terraform's OpenStack provider supports most OpenStack-based clouds, enabling consistent infrastructure-as-code practices across providers and environments.
EC2-Compatible API Support
Many OpenStack public clouds offer EC2-compatible endpoints, allowing AWS tooling and automation to work against OpenStack infrastructure with minimal modification.
Fit Check By Use Case
Enterprises Requiring Sovereign or National Cloud Providers
Organizations with requirements to use cloud providers within their national regulatory jurisdiction, or from nationally owned providers, will often find the best available options are OpenStack-based. Examples: German enterprises using Open Telekom Cloud, public sector organizations with national cloud requirements, enterprises in markets where hyperscalers have no regional presence
Enterprises Reducing Hyperscaler Lock-In
Organizations with a strategic objective to reduce dependency on AWS, Azure, or GCP will find OpenStack-based public clouds the most viable alternative with genuine API compatibility and a global provider ecosystem. Examples: Enterprises diversifying cloud supply chain risk, organizations with procurement policies favoring non-hyperscaler providers
Workloads Requiring Multi-Provider Portability
OpenStack's API standards enable multi-provider portability in principle, but the practical portability depends on which specific services and features are used. Workloads that stay within core OpenStack services port more easily than those using provider-specific extensions. Prerequisites: API compatibility assessment for specific workload requirements, provider feature comparison, portability testing
Enterprises Evaluating OpenStack as Primary Cloud Platform
OpenStack public cloud can serve as a primary platform for the right workload profile, but requires honest assessment of the chosen provider's managed service breadth and operational quality against enterprise requirements. Prerequisites: Provider evaluation against specific workload requirements, SLA and support assessment, compliance certification verification
Enterprises Requiring Hyperscaler-Level Managed Service Breadth
No OpenStack public cloud provider currently matches the managed service depth of AWS, Azure, or GCP. Enterprises with workloads that depend on a broad range of cloud-native managed services will find OpenStack-based alternatives limiting. Examples: Enterprises dependent on managed ML platforms, advanced analytics services, or extensive cloud-native service ecosystems
Enterprises Prioritizing Provider Stability and Global Support**
The OpenStack public cloud provider landscape includes providers of varying scale and stability. Enterprises that need the financial stability, global support infrastructure, and track record of a hyperscaler will find OpenStack-based alternatives a riskier choice. Examples: Enterprises with zero tolerance for provider instability, organizations requiring global 24/7 enterprise support at hyperscaler scale
How Crafty Penguins Works with OpenStack Public Cloud
OpenStack public cloud comes up in our enterprise work in the context of sovereignty requirements, hyperscaler diversification strategies, and occasionally in environments where a specific national or regional provider is the mandated or preferred choice. We help enterprises navigate the OpenStack provider landscape, which requires evaluating individual providers on their merits rather than treating OpenStack compliance as a sufficient selection criterion. For enterprises moving workloads to OpenStack public cloud, we help with architecture design, API compatibility assessment, and the Terraform and tooling setup that makes OpenStack environments manageable at enterprise scale. We also help enterprises design multi-provider strategies that use OpenStack's portability advantages deliberately rather than accidentally.
