When people begin learning cloud networking, they often start with a single VPC.

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

Organizations separate workloads for:

Security

Scalability

Team isolation

Environment segmentation (Dev, Staging, Production)

At that point, a new question arises:

How do these isolated networks communicate with each other securely?

That’s exactly what this hands-on project explores.

What We’ll Be Building

In this guide, we will:

Create two separate VPCs

Design public and private subnets in each VPC

Establish a VPC Peering connection

Configure route tables to enable communication

By the end, we’ll have a basic multi-VPC architecture, similar to what is used in real production environments.

Why This Matters

This project introduces core networking concepts every cloud engineer must understand:

Network isolation

CIDR block design

Routing between networks

Private communication without the internet

These are…
