Building a Multi-VPC Architecture on AWS
This article provides a hands-on guide to building a multi-VPC architecture on AWS using VPC peering. It walks through creating two VPCs with public and private subnets, establishing a peering connection, and configuring route tables for internal communication. The setup demonstrates foundational cloud networking concepts used in real-world production environments.
- ▪The guide demonstrates creating two VPCs (VPC-A and VPC-B) with non-overlapping CIDR blocks (10.10.0.0/16 and 10.20.0.0/16).
- ▪VPC peering is established between the two VPCs to enable secure, private communication without using the internet.
- ▪Route tables in both VPCs must be manually updated to route traffic through the peering connection for communication to work.
- ▪VPC peering has limitations, including no transitive routing and the requirement for non-overlapping CIDR blocks.
- ▪This architecture is commonly used for environment segmentation, team isolation, and microservices communication in production cloud environments.

And that’s fine… until you realize that real-world cloud environments rarely stop at just one VPC.
