AWS VPC Peering
AWS VPC Peering is a networking service that allows you to connect two Amazon Virtual Private Clouds (VPCs) in the same or different AWS accounts or regions, enabling them to communicate privately using private IP addresses. It establishes a direct network route between VPCs without traversing the public internet, VPNs, or AWS Direct Connect, providing low-latency and secure connectivity. This service is commonly used for sharing resources, data replication, or creating multi-tier applications across VPCs.
Developers should use AWS VPC Peering when building distributed applications that require secure, private communication between VPCs, such as connecting production and development environments, sharing databases or services, or implementing disaster recovery setups. It is ideal for scenarios where you need to avoid public internet exposure for sensitive data, reduce latency, and simplify network management within AWS, making it essential for cloud-native architectures and hybrid cloud deployments.
