Apache OpenWhisk is a powerful serverless platform enabling developers to build scalable, event-driven applications with minimal infrastructure management.

Core Features

  • Event-driven architecture: Execute code in response to events from external triggers (e.g., MQTT messages, HTTP requests, database changes). For example, sensor data can trigger database updates via rules linking triggers to actions.
  • Web Actions: Serve dynamic or static web content directly through REST APIs without authentication. Return HTML, JSON, images, or custom headers (e.g., cookies, redirects) for full web application support.
  • Action Sequences: Chain multiple actions into workflows, passing outputs between steps. Built-in utilities like split and sort simplify data processing pipelines.
  • Polyglot Runtime Support: Write functions in JavaScript, Python, Java, or other languages, with automatic scaling based on demand.
  • Integrated Tooling: Use the wsk CLI for deployment, logging, and monitoring, or integrate with DevOps pipelines for automated workflows.

Use Cases

  • IoT data processing (e.g., real-time sensor analytics).
  • Web/mobile backends with dynamic API responses.
  • Batch data transformations using sequential workflows.
