What does VPC Peering allow users to do?

VPC Peering enables users to connect two Virtual Private Clouds (VPCs) within Alibaba Cloud, facilitating the secure sharing of resources between them. This feature is particularly valuable for organizations that want to segregate their environments yet still need to interact frequently between different projects, departments, or applications within the cloud. By establishing a peering connection, users can create a direct network route between the VPCs, allowing for seamless communication, resource access, and enhanced collaboration.

This secure connection does not rely on the public internet, which helps minimize latency and improve security, as traffic remains entirely within the Alibaba Cloud infrastructure. Users can leverage this functionality for a variety of use cases, such as sharing databases, applications, or other services across different VPCs without the complication of heavyweight network architecture.

The other options do not accurately describe VPC Peering. The first option pertains to connecting VPNs to physical locations, which involves a different mechanism focused on connecting on-premises networks with cloud environments, not specifically related to VPCs in the same cloud. The second option discusses connecting multiple cloud providers, which is more aligned with cross-cloud networking strategies rather than the focus of VPC Peering within a single cloud environment. Lastly, the idea of creating duplicate
