Have you ever wanted to connect two separate VPCs (Virtual Private Clouds) within your AWS environment? Look no further than VPC peering! This powerful feature allows you to establish secure, private communication channels between your VPCs, enabling instances in each to interact with each other as if they were on the same network.
Key benefits of VPC peering:
- Private connectivity: Forget the public internet! VPC peering keeps traffic flowing exclusively on the secure AWS global backbone, minimizing security risks.
- Cross-account and cross-region: Need to connect VPCs in different accounts or even different regions? VPC peering makes it a breeze.
- Cost-effective: Enjoy free data transfer within the same Availability Zone. Charges may apply for cross-AZ data transfer.
How does it work?
- Initiate the connection: The owner of the "requester VPC" sends a request to the owner of the "accepted VPC."
- Handshake complete: Once accepted, both VPCs configure their route tables to route traffic to the peered VPC and update their security groups to allow incoming traffic.
