Cloud Networking Simplified: Setting Up AWS VPC Peering Across Regions

VPC Peering allows for secure, private communication between resources in different Virtual Private Clouds (VPCs).

1. Why We Need This Use Case

VPC Peering allows for secure, private communication between resources in different Virtual Private Clouds (VPCs). When resources in different AWS regions need to communicate, VPC peering provides a viable solution. It enables data transfer between VPCs across regions while ensuring the traffic remains within the AWS network, offering lower latency, high security, and reduced cost compared to public internet routing.

2. When We Need This Use Case

• When deploying multi-region architectures for high availability and disaster recovery.

• When applications hosted in different AWS regions need direct, low-latency communication.

• When integrating workloads across VPCs in separate regions without exposing them to the public internet.

• When consolidating resources across regions to optimize performance and cost.

• When establishing inter-region connectivity while ensuring security and compliance.
