What can help in achieving lower latency between AWS resources across different regions?

Utilizing a public subnet for all instances
Using cross-region VPC peering
Implementing AWS Lambda functions
Establishing a local transit hub

The correct answer is: Establishing a local transit hub

Establishing a local transit hub can significantly contribute to achieving lower latency between AWS resources across different regions. A local transit hub enables efficient routing of traffic between different VPCs and AWS services, facilitating optimized pathways for inter-region communication. By centralizing the traffic management in a transit hub, data can be transferred more quickly and reliably across regions, reducing latency compared to more direct but less optimized connection methods. In contrast, while cross-region VPC peering allows direct communication between resources in different VPCs across regions, it does not inherently optimize latency as effectively as a centralized transit solution. Utilizing a public subnet for all instances focuses more on accessibility rather than on minimizing latency, and implementing AWS Lambda functions may not directly contribute to reducing latency between regions as they are designed for event-based processing rather than facilitating networking connections.
