Amazon ECS
Amazon Elastic Container Service (ECS) is a container orchestration platform which can run containers on EC2 instances or serverless using Fargate. For many container-based systems we find ECS to be a good choice thanks to its simplicity, maturity and basic but competent feature set.
Compared to Kubernetes, ECS is significantly simpler to adopt and operate but lacks the extensibility to cater for advanced scenarios. In most cases these scenarios do not arise and this is a good trade-off.
