The mission of Apache OpenWhisk is to provide a complete platform for building Serverless , or Function-as-a-Service, platform applications with Functions, along with an ecosystem of curated functional packagesevent-providers, client SDKs and integration tooling.
...
The OpenWhisk project offers a truly open, highly scalable, performant distributed Serverless computing platform for Functions, leveraging other open technologies along with a robust programming model, catalog of service and event provider integrations and developer tooling. Specifically, every architectural component service of the OpenWhisk platform (e.g., Controller, Invokers, Messaging, Router, Catalog, API Gateway, etc.) all is designed to be run and scaled as a Docker container. In addition, OpenWhisk uniquely leverages aspects of Docker engine to manage, load balance and scale supported OpenWhisk runtime environments (e.g., JavaScript, Python, Swift, Java, etc.), that run Serverless functional code within Invoker compute instances, using Docker containers.
