Which open source platform is IBM Cloud Functions based on?

IBM Cloud Functions is built on Apache OpenWhisk, which is an open-source serverless platform. This framework enables the execution of code in response to events without the need to manage the underlying infrastructure.

OpenWhisk allows developers to write functions or "actions" that can be triggered by various event sources such as HTTP requests, changes in a database, or messages from a queue. This functionality aligns with the serverless architecture that IBM Cloud Functions provides, allowing users to focus solely on the code they write instead of worrying about deployment or scaling their applications.

Choosing Apache OpenWhisk as the foundation of IBM Cloud Functions brings with it the advantages of an established community, extensibility, and support for multiple programming languages. This provides developers a robust environment to create scalable applications with minimal operational overhead.
