An image-processing application on Amazon EC2 within a single VPC spans multiple Availability Zones without inter-instance communication. It uses a single NAT gateway for S3 image transfers. How can the company minimize Regional data transfer costs?
Explanation:
The most cost-effective way to avoid Regional data transfer charges is to deploy a VPC endpoint for S3. This allows instances in the VPC to communicate directly with S3 without needing to traverse the internet, thereby eliminating data transfer charges associated with the NAT gateway. Options A and B still incur data transfer costs, and Option D does not address the data transfer issue.
