VPC Peering Project 🚀

Welcome to the VPC Peering Project! In this project, we're taking a big step forward by setting up VPC Peering, connecting TWO VPCs instead of just one. This project will help you revise and solidify your previous knowledge in a new and exciting scenario.

Introduction

In this project, you'll get hands-on experience with setting up VPC Peering between two Virtual Private Clouds (VPCs). This will enhance your understanding of network segmentation, security, and connectivity within the AWS environment.

Project Overview

Objectives

• ☁️ Set up multiple VPCs.
• 🌉 Create a VPC peering connection to enable communication between two VPCs.
• 👩‍🔬 Test VPC peering with connectivity tests.

Prerequisites

Before you start, ensure you have:

• An AWS account.
• Basic knowledge of VPCs, subnets, and route tables.
• Familiarity with the AWS Management Console.

Setup Guide

Step 1: Create VPCs

First, we'll create two VPCs to be connected via VPC Peering.

• Create VPC 1 → Configure Subnets & Routing for VPC 1
• Create VPC 2 → Configure Subnets & Routing for VPC 2

Step 2: Set Up VPC Peering

Step 2: Set Up VPC Peering Next, we'll establish a peering connection between the two VPCs.

1. Request a VPC Peering Connection from VPC 1 to VPC 2.
2. Accept the VPC Peering Connection in VPC 2.

Flow:

• Request Peering from VPC 1 → Accept Peering in VPC 2

Step 3: Configure Route Tables

1. Update the Route Table in VPC 1 to route traffic to VPC 2.
2. Update the Route Table in VPC 2 to route traffic to VPC 1.

Flow:

• Update Route Table in VPC 1 → Add Route to VPC 2
• Update Route Table in VPC 2 → Add Route to VPC 1

Step 4: Test Connectivity

1. Launch EC2 instances in both VPCs.
2. Test connectivity between the instances using ping or similar network tools.

Flow:

• Launch EC2 in VPC 1 → Launch EC2 in VPC 2
• Ping from VPC 1 to VPC 2 → Ping from VPC 2 to VPC 1 → Verify Connection
