Introduction: VPC Peering Demystified
In cloud computing, seamless connectivity between Virtual Private Clouds (VPCs) across regions is a game-changer. VPC Peering allows you to connect VPCs from different areas, enabling efficient data transfer and resource sharing. This guide will walk you through setting up VPC Peering between two AWS regions, Mumbai and N. Virginia, ensuring a robust and interconnected cloud infrastructure.
Prerequisites: Your VPC Peering Toolkit
Before diving into VPC Peering, ensure you have the following:
- AWS accounts with necessary permissions
- Two VPCs in different regions (Mumbai and N. Virginia)
- Familiarity with AWS Management Console
- Basic understanding of networking concepts

The Power of VPC Peering: Benefits, Components, and Steps
Benefits of VPC Peering
- Enhanced Security: Direct connection without traversing the public internet
- Cost Efficiency: Avoids data transfer costs associated with internet gateways
- Low Latency: Improved performance for inter-region data transfer
Components of VPC Peering
- VPCs: The isolated networks to be connected
- Peering Connection: The link established between VPCs
- Route Tables: Configurations directing traffic between VPCs
Creating Your VPC Kingdoms: Mumbai and N. Virginia
Mumbai VPC
- Create VPC: Navigate to the VPC dashboard, select the Mumbai region, and create a new VPC.
- Subnets: Create subnets within the VPC.
- Route Tables: Configure route tables for traffic management.
N. Virginia VPC
- Create VPC: Switch to N. Virginia region and create a new VPC.
- Subnets: Set up subnets within the VPC.
- Route Tables: Configure route tables for traffic management.
VPC Peering Configuration: Establishing Connections
- Request Peering Connection: In the Mumbai VPC, request a peering connection to the N. Virginia VPC.
- Accept Peering Connection: Switch to the N. Virginia VPC and accept the peering request.
- Update Route Tables: Modify route tables in both VPCs to enable traffic flow.
Launching Your Cloud Instances: Deployment Steps
- Deploy Instances in Mumbai: Launch EC2 instances within subnets of the Mumbai VPC.
- Deploy Instances in N. Virginia: Launch EC2 instances within subnets of the N. Virginia VPC.
Testing the Connection: Verifying Reachability
- Ping Test: From an instance in Mumbai, ping an instance in N. Virginia.
- Connectivity Check: Ensure that instances can communicate with each other seamlessly.
Conclusion: Your VPC Peering Mastery
Congratulations! You have successfully established a VPC Peering connection between Mumbai and N. Virginia, creating a resilient and interconnected cloud infrastructure. This setup enhances security, reduces costs, and improves performance across your AWS environment.
