Amazon ECS vs Amazon EKS

Accepted Answer

1. Amazon ECS is the AWS solution for managing containers at scale. It helps you speed up the process of building, deploying and migrating your containerized applications. Designed with simplicity in mind, Amazon ECS reduces the burden of setting up network, compute and security configurations, and managing scalability. For example, you don’t need to build a generalized abstraction if you need a load balancer—ECS seamlessly integrates features such as AWS Application Load Balancer (ALB) and Network Load Balancer (NLB).
Amazon EKS can handle the heavy lifting of building and running Kubernetes workloads at scale. Kubernetes is known for its vibrant community and ecosystem, open-source APIs and broad flexibility. With EKS, you can access the full power of Kubernetes features, while enjoying the convenience of a managed cloud service.

2. In terms of security, the difference between ECS and EKS is strictly operational—ECS has a deep integration with IAM while EKS requires add-ons to enable IAM functionality. Other options that enable similar functions in EKS, such as Kiam, have additional costs and add system complexity.

3. Amazon ECS is a proprietary technology by AWS. This means you will be locked into Amazon infrastructure and will not be able to move your clusters to another cloud provider or on-premises.
Amazon EKS is based on Kubernetes, so it has much better support for portability of workloads. You can run clusters in any other Kubernetes environment, whether on another cloud provider’s managed Kubernetes platform, a cloud-agnostic Kubernetes platform like Rancher, or plain self-managed Kubernetes.

4. Amazon ECS is not an open-source product, so it does not have a community as such. The product is supported by Amazon—see pricing for the available support plans.Amazon EKS is based on Kubernetes, so you have access to the Kubernetes community, including Github repos, Slack channels, events, documentation, training resources, and more.
