Amazon Elastic Container Service (ECS) is a fully managed container orchestration service that simplifies deploying, managing, and scaling containerized applications on AWS. With ECS, you can efficiently run and scale Docker containers across a cluster of EC2 instances or AWS Fargate compute resources without managing the underlying infrastructure. With ECS, you can also focus on developing and deploying your applications while AWS handles the infrastructure and scaling.
In this Cloud Lab, you will create an ECS service using blue/green deployment. You’ll start by creating an IAM role and security groups. After that, you’ll create two ECR repositories. Then, you’ll create two images and push them to those repositories. Next, you’ll create an ECS cluster and a task definition with one of the images stored earlier. You’ll also create an application load balancer, which will be used later for blue/green deployment. After creating these resources, you’ll create a simple ECS service. Once your app runs, you’ll change the task definition to see how it affects it.
By the end of this Cloud Lab, you’ll have practical experience in creating an ECS service with blue/green deployment. These skills are essential for anyone working with containerized applications on AWS and will help you ensure the scalability and reliability of your applications.
The following is the high-level architecture diagram of the infrastructure that you’ll create in this Cloud Lab:
