What is the purpose of Amazon VPC Peering?

Amazon VPC Peering is primarily designed to connect two Virtual Private Clouds (VPCs), enabling resources within those VPCs to interact privately. This allows for secure communication between VPCs without traversing the public internet, enhancing data security and reducing the risk of exposure to external threats. With VPC Peering, resources can communicate using private IP addresses, making it a seamless way for different AWS accounts, or even VPCs within the same account, to share resources, applications, and services while maintaining high levels of security and control.

The capability of private communication through peering is particularly valuable in scenarios where organizations need to manage separate environments for production, testing, or development, while still allowing specific interactions between them. It ensures that data transfer between the two environments adheres to internal security policies and does not go through an outside network.

The other options do not accurately reflect the primary function of Amazon VPC Peering. Public access to cloud resources is typically managed through other AWS features, not through peering. While additional IP addresses might be necessary for certain configurations, that is not the purpose of VPC Peering. Lastly, while peering connects VPCs effectively, its main focus is not to enhance the speed of network connections
