What is VPC Peering used for in cloud networks?

VPC Peering is primarily used to simulate a single network between two Virtual Private Clouds (VPCs) within a cloud environment. This connection allows for direct, private communication between the VPCs as if they were part of the same network. It facilitates resource sharing, enabling instances in one VPC to communicate with instances in another VPC using private IP addresses. This configuration enhances collaboration between different projects or departments within an organization, while maintaining the benefits of network isolation and security.

By using VPC Peering, users can link their cloud resources without the need for public internet pathways, ensuring a more secure and efficient connection compared to traversing the public internet. This can greatly improve the performance and reliability of applications that rely on data exchange between the two VPCs.

In contrast to other options, VPC Peering is not designed specifically to enhance data redundancy, provide public internet connections, or isolate traffic across different regions. Instead, it focuses on creating a direct pathway for secure communication between the two VPCs, which is crucial for effective cloud network management.
