Reference Architectures

Think of these as curated playlists of OpenStack configurations. These Reference Architectures are based on real-world workloads. The Reference Architecture document will give you a good idea of which core and optional projects might be used by the workload. In addition, each Reference Architecture includes sample Heat and or Murano packages which will allow you to reproduce the workload in your own environment.

A software development kit (SDK) contains code, examples, and documentation that you use to create OpenStack cloud applications in the language of your choice.

If one of the following SDKs do not support your language or use case, you can use the APIs or one of the other known SDKs.

An application programming interface (API) lets you access service capabilities through predefined functions.

To learn how to use the APIs, see the OpenStack API Guide. All documented OpenStack APIs are listed on the API Reference Guide page.



A command-line interface (CLI) is a text-based client that helps you create scripts to interact with OpenStack clouds.

To install the CLIs, see Install the CLIs.

To use the CLIs, see OpenStack command-line clients.
