You run a high-throughput critical application in your on-prem datacenter, the application tier uses several virtual machines and is backed by an on-premise MySQL server for storing transactional data. Due to increase in demand, you need to scale out the application but there is no additional space in your on-premise datacenter. Your CTO has asked you to explore the possibility of migrating the application tier to Google Cloud, however, the MySQL database needs to stay on-premise due to regulatory requirements. Your security officer has insisted any communication between the application tier and the database happens over internal IPs. Given the critical nature of application, you also need to ensure the latency between the application tier and the database tier is minimized. You want to follow Google Recommended practices. What should you do?
