Description: The VPC (Virtual Private Cloud) peering connection is a fundamental resource in Amazon Web Services (AWS) infrastructure that allows communication between two VPCs. This connection is established securely and efficiently, facilitating the exchange of data and resources between isolated networks. Each VPC can be in the same region or in different regions, providing flexibility in network architecture. The peering connection allows instances in one VPC to access resources in another VPC, such as databases, applications, and services, without needing to go through the public Internet, which enhances security and reduces latency. Additionally, peering connections are scalable and can be configured to allow bidirectional or unidirectional traffic, depending on user needs. This type of connection is particularly useful in cloud environments where smooth communication is required between different departments or applications operating in separate VPCs. In summary, the VPC peering connection is a key tool for optimizing connectivity and security in the cloud.
