Using VPC Network Peering offers the advantage of allowing secure resource sharing between Virtual Private Clouds (VPCs). This connection facilitates direct communication between two VPCs without exposing traffic to the public internet, thereby enhancing security while enabling resources in one VPC to be accessed from another seamlessly.
One of the primary benefits of VPC network peering is that it establishes a private network path between VPCs, making it suitable for organizations that need to share applications, databases, or other services across different environments while maintaining a secure framework. This peering connection essentially treats resources in both VPCs as part of the same network, allowing for efficient communication and collaboration.
In contrast, options such as reducing latency by routing through the internet, requiring public IP addresses, and simplifying external DNS management fail to capture the essence of what VPC Network Peering is designed to achieve. Network peering operates entirely over private IP addresses and is specifically focused on improving the security and efficiency of inter-VPC communications rather than relying on public internet pathways or external DNS considerations.
