AWS re:Invent 2021 - Application integration patterns for microservices 

Surprised to see SNS in the discussion around 41:00. I'm thinking EventBridge would be a better choice.

How Synchronous microservices talk to each other on cloud i.e on AWS without using QUEUE. Suppose there are 2 microservices A& B which are deployed on AWS ec2 instance. I cant hardcode B endpoint inside A microservice. Bcz everytime Ec2 instance started , the IP gets changed.

Great presentation with good examples

Informative. Thanks a lot.
