About the Book

The goal of this book is to provide an introduction to using the Go programming language (Golang) on the IBM Cloud. The same example application—a TodoBackend—is built using two different IBM Cloud offerings—IBM Cloud Foundry and IBM Cloud Functions—to see the differences between the two deployment options. IBM Cloud Foundry is IBM's offering of Cloud Foundry, an open source cloud application platform. IBM Cloud Functions is IBM's offering of Apache OpenWhisk, an open source, distributed serverless platform that executes functions in response to events at any scale.
