This pattern describes how to privately host a Docker container application on the Amazon Web Services (AWS) Cloud by using Amazon Elastic Container Service (Amazon ECS) with an AWS Fargate launch type, behind a Network Load Balancer, and access the application by using AWS PrivateLink. Amazon Relational Database Service (Amazon RDS) hosts the relational database for the application running on Amazon ECS with high availability (HA). You can use Amazon Elastic File System (Amazon EFS) if the application requires persistent storage.
This pattern uses a Fargate launch type for the Amazon ECS service running the Docker applications, with a Network Load Balancer at the front end. It can then be associated with a virtual private cloud (VPC) endpoint for access through AWS PrivateLink. This VPC endpoint service can then be shared with other VPCs by using their VPC endpoints.
You can use Fargate with Amazon ECS to run containers without having to manage servers or clusters of Amazon Elastic Compute Cloud (Amazon EC2) instances. You can also use an Amazon EC2 Auto Scaling group instead of Fargate.
