Summary

In this chapter, we looked at the infrastructure architecture of our legacy application and designed a simple initial infrastructure architecture for moving the application into the Google cloud. We decided that there would be no changes to the application code base, and we would only be changing the infrastructure. The infrastructure architecture did not address concerns such as scalability or availability, but instead focused on hosting our functionality and on network security between the layers of our application.

We then created our organizational structure and the project we will be working on throughout this book. Next, we implemented the firewall rules and the three VMs using the Marketplace. Then, we introduced persistence with a MySQL VM, sessions storage using the Redis VM, and an application web server with the Tomcat VM. Finally, we deployed our application and performed a basic test to see if we could access it.
