Donated to the Apache foundation, OpenWhisk is a robust FaaS platform originally developed by IBM and Adobe. Built atop Docker container technologies, OpenWhisk can be deployed in the cloud or on on-premises hardware. It is a platform that frees developers from worrying about managing the life cycle of their code or operations of the container runtimes that execute the code. OpenWhisk is designed to be scalable and to support massive numbers of function invocations. Currently, OpenWhisk is the engine behind IBM Cloud Functions.

For developers, OpenWhisk provides a number of compelling features...
