GAE allows new versions to deploy and more besides, performing more complex operations such as traffic splitting. As we have already deployed a simple application from the command line, let's continue with this code base and look at how to implement a new version using the GAE management console.
Understanding the mechanism behind the GAE console used to control the flow of code is invaluable. Being able to deploy a new system via a rollout provides a good layer of control over the application environment. Taking this to the next level, we can also split traffic between versions to perform sophisticated A/B testing.
