There are some ways to mitigate the latency your clients experience. You can generally improve the performance of your application delivery infrastructure by utilizing features such as the Route53 DNS system and CloudFront caching, as well as the CDN environment. Services that help with delivery to clients are delivered from edge locations. These are locations that are separate from the datacenters that the AWS availability zones reside in and are positioned closer to where traffic from end users is coming from. In some geographical locations, the edge locations are positioned close to where the AWS region exists so that the experience delivered to end users is close to what it would be if a region was located nearby. However, these services are optional and do carry a certain cost, so it is up to the system architect building the solution to evaluate whether the cost of running a service in an edge location will be beneficial and is a justified expense.

The following map shows the edge locations in relation to their closest regions:
