In the next lesson, I'm going to talk about traffic splitting when deploying multiple app versions. That being the case, I just wanted to briefly touch on the deployment of multiple app versions. However, because the deployment process for multiple versions is identical to the deployment of the first version, I'm not going to do a full demonstration. Instead, I'm just going to tell you that to deploy multiple versions of an app, you can simply rerun the gcloud app deploy command that we covered in the last lesson. By doing so, another copy of the app will be deployed and GCP will automatically generate a version for it. You can rerun the gcloud app deploy to create as many versions of your application that you need. If you need a different configuration for each version, as will be the case when doing A/B testing, you would just modify the configuration of the web app and then rerun the gcloud app deploy command. 

So, with that said, let's hop into the next lesson so I can explain traffic splitting.
