The AWS App Mesh introduces enhanced ingress traffic management capabilities. Now you can control how App Mesh rewrites external requests, so that they reach the correct destination within your mesh. You also have greater flexibility controlling how the requests are matched to the destinations in the Gateway and Virtual Router Routes. AWS App Mesh is a service mesh that provides application-level networking to standardize how your services communicate, giving you end-to-end visibility and options to tune for high-availability of your applications.
