Apache OpenWhisk is an open-source distributed serverless platform that allows developers to execute functions in response to events at any scale. By managing infrastructure and scaling through Docker containers, OpenWhisk enables users to concentrate on crafting efficient applications. The platform supports a programming model where developers can write functional logic, referred to as Actions, in various programming languages. These Actions can be dynamically scheduled and executed based on events from external sources or HTTP requests.

The platform features a REST API-based Command Line Interface (CLI) along with additional tools for packaging and cataloging services. Apache OpenWhisk is compatible with popular container frameworks and offers deployment options both locally and in cloud environments. It serves a diverse audience, including small businesses, enterprises, and government organizations, making it a flexible solution for serverless computing.
