Apache OpenWhisk vs. Azure Functions vs. IBM Cloud Functions vs. Wing Python IDE Comparison Chart

Apache OpenWhisk is an open source, distributed Serverless platform that executes functions (fx) in response to events at any scale. OpenWhisk manages the infrastructure, servers and scaling using Docker containers so you can focus on building amazing and efficient applications. The OpenWhisk platform supports a programming model in which developers write functional logic (called Actions), in any supported programming language, that can be dynamically scheduled and run in response to associated events (via Triggers) from external sources (Feeds) or from HTTP requests. The project includes a REST API-based Command Line Interface (CLI) along with other tooling to support packaging, catalog services and many popular container deployment options. Since Apache OpenWhisk builds its components using containers it easily supports many deployment options both locally and within Cloud infrastructures. Options include many of today's popular Container frameworks.

Based on Apache OpenWhisk, IBM Cloud Functions is a polyglot functions-as-a-service (FaaS) programming platform for developing lightweight code that scalably executes on demand. IBM Cloud Functions offers access to the Apache OpenWhisk ecosystem, where anyone can contribute code. IBM Cloud Functions enables developers to build apps with action sequences that execute in response to events. IBM Cloud Functions makes cognitive analysis of application data inherent to your workflows. Costs increase only as you construct more OpenWhisk-intensive solutions or need to support larger workloads.
