This tag should be used when the questions asked concern about the latency of data transferred between the user and their application when they want to leverage AWS internal network and avoid internet hops and automatic failover.
The questions which can use this tag would be of the following :-
when they want intelligent routing and automatic fast regional failover, and heath checks which are suitable for disaster recovery.
when the questions involve rendering of dynamic content instead of cached content.
When they want to leverage DDOS protection using AWS shield, transfer data through AWS private network.
when they want to expose 2 static IP ADDRESS and uses a s3,alb,nlb,HTTP endpoint.
when the application wants to leverage the idea of anycast IP that multiple servers holds same IP address,where client connect to the nearest server.
USE CASE
when a user have a global application but it is deployed in specific region and have global users who want to access it directly without any latency issue.
