AWS ECS : Network Modes and Comparison
In this post, I will discuss the container networking options available with AWS ECS, their applicability and brief comparison.
Overview
Container networking refers to the ability for containers to connect to and communicate with each other, or to non-Docker workloads.
This is the definition provided by docker, and it’s applicable for ECS as well.
Lets take an example of a TODO application which manages the TODO entries. Let say, the TODO Application is running as an ECS Task. You have another containerized application called Reminder Application, which takes care of managing the “reminders”. The reminder application is running as a separate Task. Every time a TODO entry is created with a Reminder, TODO Application need to connect with the Reminder Application. Your container or Task needs to be available for any external communications as well, for instance from a load balancer.
