Step-by-step Instructions to Setup an AWS ECS Cluster

Configuring AWS ECS to have access to AWS EFS

If you would like to persist data from your ECS containers, i.e. hosting databases like MySQL or MongoDB with Docker, you need to ensure that you can mount the data directory of the database in the container to volume that's not going to dissappear when your container or worse yet, the EC2 instance that hosts your containers, is restarted or scaled up or down for any reason.

Don't know how to create your own AWS ECS Cluster? Go here!

New Cluster

Sadly the EC2 provisioning process doesn't allow you to configure EFS during the initial config. After your create your cluster, follow the guide below.

New Task Definition for Web App

If you're using an Alpine-based Node server like duluca/minimal-node-web-server follow this guide:

AWS Region Names

Alternative naming schemes for AWS regions

Purpose

The intent is to define terse, standards-supported names for AWS regions.

Session Management in an Autoscaling Environment

Problem Statement

User sessions in J2EE and LAMP stacks have traditionally been handled in memory by the application server handling the user request. Because of that, load balancers have been configured to use sticky sessions. By sticky sessions we mean that once the user has visited the site, they will be assigned an app server and will return to that server for subsequent requests. The load balancers typically handle that by referencing the users session cookie.

Elastic cloud environments differ from traditional server configurations in that they have a variable number of servers based on traffic loads whereas traditional configurations had a fixed number of servers. When traffic volumes decline it is necessary to vaporize servers. In doing so, we would lose user sessions (essentially forcing a logout) unless we come up with a new strategy for session management.

A new approach

After much research, it is clear that the best
