Welcome back. In the last lesson, we talked a little bit about traffic splitting. What I want to do here is show you how to do it via the console. It's actually rather easy to do, but it makes sense to demonstrate how it's done. 

As you can see here on your screen, I'm in the App Engine dashboard. What I'm going to do here is click over here on Versions. Now what this shows is two versions of my app that I deployed earlier. If you notice, only one of these apps is receiving all of the traffic. 

To split traffic across both of these versions, I just need to click Split Traffic up here at the top, and then from here, I can choose my split option. For this exercise, I'm going to choose Random. Clicking add version allows me to add my second version of the app to the split, and then from here, I can configure the split percentages. 

With my split configured, I just have to click Save to save my split configuration. Now what this configuration does is randomly split traffic evenly across both versions of my application, and if we go back here, we can see the 50-50 split. 

So that, in a nutshell, is how you configure traffic splitting across multiple versions of an application.
