GCP VPC Architecture Design

This template is your go-to guide for building and understanding a well-structured network in Google Cloud. Think of it as mapping out different neighbourhoods in a city (your projects), each with its own local roads, but also connected to shared highways (your shared VPC). This diagram helps cloud architects truly grasp the design of both shared and standalone VPCs (Virtual Private Clouds), illustrating: 

• Shared Networks (Shared VPCs): It clearly shows how a central VPC Host Project manages shared networking resources, allowing multiple Service Project Pods to securely connect and operate within a single, managed network. 

• Segmenting Your Space: The template highlights GCP network segmentation by showing separate VPCs for different purposes: VPC Prod (for live systems), VPC Test (for development), VPC Sandbox (for experiments), and VPC Infra (for core infrastructure). 

• Security at the Edges: It includes a VPC DMZ (Demilitarized Zone) to handle external traffic securely and demonstrates how a Firewall Appliance protects network boundaries. 

• Connecting It All: It visualizes Google Cloud Router and Google Cloud Interconnect for hybrid cloud connectivity (linking your cloud to your physical offices). 

• Traffic Management: You'll see how Google Cloud Load Balancer efficiently distributes traffic across VM Instances hosting your applications. 

• Inter-VPC Communication: While not explicitly named "peering" in components, the design implies and facilitates communication strategies like VPC peering between different isolated networks for specific needs. 

Why Use This VPC Architecture Template? 

Using this template offers big advantages for your Google Cloud networking efforts: 

• Master GCP VPC Architecture: Get a crystal-clear understanding of how to structure your VPCs, whether they're shared or standalone. 

• Achieve Smart GCP Network Segmentation: Plan and visualize how to isolate different environments and workloads, boosting security and organization. 

• Understand Shared VPCs: Clearly see how a Shared VPC allows multiple projects to use the same network infrastructure, simplifying management and consistency. 

• Facilitate VPC Peering Scenarios: While not a direct component, the template's structure naturally lends itself to understanding where and why VPC peering might be used to connect separate VPCs securely. 

• Improve Security Posture: Define and visualize Firewall Policies and DMZ setups to protect your network boundaries effectively. 

• Optimize Network Performance: Understand how Load Balancers distribute traffic and how hybrid connectivity solutions integrate. 

• Streamline Collaboration: Provide a common, visual language for cloud architects, network engineers, and development teams to discuss and agree on Google Cloud networking strategies.

• VPC Test: Provides testing and development environments (another segmented VPC). 

• VPC Sandbox: Isolates experimental projects. 

• VPC Infra: Manages infrastructure-related workloads. 

• VM Instances: Hosts application and compute services. 

• Shared VPC Services: Connects multiple projects through a shared network. 

• Google Cloud Router: Handles dynamic routing for hybrid cloud connectivity. 

• External Client: Represents user access from outside the network. 

• Google Cloud Load Balancer: Distributes traffic across VMs efficiently.
