Today “the Cloud” is everywhere, it permeates our lives, and it is impossible to imagine ourselves without it. Without Cloud technology, we wouldn’t have globally available applications like Airbnb, Uber, Facebook, Google, IBM Cloud, Netflix, Apple iTunes, Amazon, and Microsoft Azure, to name but a few cloud-based services.

It wouldn’t be fair to just jump ahead and start the discussion of Apache OpenWhisk without providing some information about the Serverless technology vendor landscape. This chapter will therefore focus on providing an introduction to the Serverless space, as well as providing arguments for using one or the other Serverless platforms. At the moment of writing, only Apache OpenWhisk supports the Swift language; thus, only IBM Cloud with IBM Cloud Functions is described in the following chapters.

Marek speaking: “Most of my 20+ year IT career has been with server-side Java. It started with Sun Microsystems’ Java when it was a new language used mostly in web page applets in 1995-97. Back in 1996 I started my Java adventure by writing one of the first server-side Java systems creating Web Forums dedicated to the Disaster Recovery in NTT in Japan. Since then plenty of new and old systems were built or migrated to server-side Java and eventually to the cloud.
