Designing a multi-project cloud architecture requiring centralized network control
Use cases
About
The Deploying and Implementing Networking Resources mind map template is a technical guide for IT architects and cloud engineers managing Google Cloud Platform (GCP) environments. This 194-node cheat sheet provides a structured breakdown of critical infrastructure components including Firewall rules, Shared VPC architectures, and VPN configurations. It serves as a comprehensive reference for implementing stateful security policies, managing cross-project networking, and establishing secure site-to-site connectivity. The template specifically details how Firewall rules are enforced at the instance level and how a Shared VPC can be utilized to centralize network management across multiple service projects within a single organization. By mapping out these complex relationships, the template helps teams ensure high availability and security compliance during cloud deployment phases.

How to use this template
Step 1
Import the networking template
Open the .xmind file in Xmind desktop or web to access the full 194-node networking resource map.
Step 2
Map your project structure
Navigate to the Shared VPC branch and replace the generic project placeholders with your actual Host and Service project names.
Step 3
Define custom firewall rules
Use the Firewall components section to document your specific port requirements and target tags for your unique environment.
Frequently asked questions
The template notes that every network includes an implied allow egress rule and an implied deny ingress rule. It also specifies that essential services like DHCP, DNS, and Instance metadata (169.254.169.254) are always allowed, while GRE traffic and SMTP port 25 are blocked by default.
A Shared VPC allows a central Host project to share a network across multiple Service projects. This enables separate departments to maintain ownership and billing for their resources while utilizing a common, centrally managed network infrastructure for better security and connectivity.
According to the VPN overview in the template, Cloud VPN gateways support up to 3 Gbps per tunnel. These are regional resources that provide low-cost, encrypted private tunnels over the public internet, making them ideal for low-volume data connections.
Yes, the template explains that Network Tags are text attributes for Compute Engine instances. You can customize these tags in Xmind to plan how you will apply specific firewall rules and routes to sets of instances within your VPC.
