This session centers around the core principles of the networking system within the Google Cloud Platform. During this hands-on session, we will establish VPC networks and deploy virtual machine instances as web servers and MySQL servers. Specifically, our focus will be on enabling communication between internal networks through the utilization of the VPC Peering feature on the Google Cloud Platform. The practical exercises will guide us through various scenarios, including Firewall Operations and IP reservations. We'll delve into real-world use cases to enhance our understanding of the concepts presented.
