Amazon Virtual Private Cloud (VPC) provides a customizable and isolated network environment within AWS. VPC Peering connects these isolated networks securely, enabling cross-VPC communication without overlapping IP address ranges.

1. Create two VPCs with unique CIDR blocks.
2. Establish a peering connection between the VPCs.
3. Update routing tables to allow cross-VPC traffic.
4. Validate connectivity through successful communication between instances in each VPC.

• Created VPCs: Configured VPC1 (10.1.0.0/16) and VPC2 (10.2.0.0/16) with public subnets.
• Deployed EC2 Instances: Launched one instance in each VPC and configured appropriate SSH access.

VPC setup overview.

• Peering Request: Established peering between VPC1 (Requester) and VPC2 (Accepter).
• Route Table Updates: Configured route tables to direct cross-VPC traffic via the peering connection.

Peering connection settings

• Security Rules Adjustment: Modified security group rules to allow ICMP (ping) and SSH traffic.
• Validation: Conducted successful ping tests between EC2 instances to confirm connectivity.

Ping results confirming successful cross-VPC communication.

1. Importance of accurate CIDR block planning to avoid overlap.
2. The need for precise configuration of security groups and routing tables.
3. Practical experience in troubleshooting connectivity issues in AWS environments.

This project successfully demonstrated VPC peering, with instances in separate VPCs communicating securely. The configuration ensures scalability, flexibility, and robust network design for AWS solutions.
