Amazon EC2 Container Service vs Docker Compose: What are the differences?
Developers describe Amazon EC2 Container Service as "Container management service that supports Docker containers". Amazon EC2 Container Service lets you launch and stop container-enabled applications with simple API calls, allows you to query the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features like security groups, EBS volumes and IAM roles. On the other hand, Docker Compose is detailed as "Define and run multi-container applications with Docker". With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.
Amazon EC2 Container Service can be classified as a tool in the "Containers as a Service" category, while Docker Compose is grouped under "Container Tools".
"Backed by amazon", "Familiar to ec2" and "Cluster based" are the key factors why developers consider Amazon EC2 Container Service; whereas "Multi-container descriptor", "Fast development environment setup" and "Easy linking of containers" are the primary reasons why Docker Compose is favored.
Docker Compose is an open source tool with 16.6K GitHub stars and 2.56K GitHub forks. Here's a link to Docker Compose's open source repository on GitHub.
According to the StackShare community, Docker Compose has a broader approval, being mentioned in 796 company stacks & 626 developers stacks; compared to Amazon EC2 Container Service, which is listed in 794 company stacks and 391 developer stacks.
If you want to integrate your cluster and control end to end your pipeline with AWS tools like ECR and Code Pipeline your best option is ECS using a EC2 instance. There are pros and cons but it's easier to integrate using cloud formation templates and visual UI for approvals, etc. ECS is free, you need to pay only for the EC2 instance but unfortunately, it is not standard then you cannot use standard tools to see and manage your Kubernetes. EKS in the other hand uses standard Kubernates definitions but you need to pay for the service and also for the EC2 instance(s) you have in your cluster.
