Amazon Elastic Kubernetes Service (Amazon EKS) is a managed container service to run and scale Kubernetes applications in the cloud or on-premises, available on AWS or on-premise through Amazon EKS Anywhere.
There is no additional charge for Amazon ECS. You pay for AWS resources (e.g., Amazon EC2 instances or Amazon EBS volumes) you create to store and run your application. You only pay for what you use, as you use it; there are no minimum fees and no upfront commitments.

Container Management
Comparison of Container Management features of Product A and Product B
Amazon Elastic Container Service (Amazon ECS) is well suited where you need the ease of managing the clusters by letting AWS do the stuff for you. Obviously, whenever you want to run the docker based workloads, it is always better to go for either AWS ECS or AWS EKS. If you are interested in staying at AWS only and don't want to be cloud-agnostic, then go for AWS ECS instead of AWS EKS. AWS ECS is cheaper than AWS EKS and also more managed by AWS and better integrated with other AWS services. If you want to run those workloads as serverless, then AWS ECS Fargate is the best option to go with. If you already have a Kubernetes based setup that you want to migrate to AWS, then go for AWS EKS instead of AWS ECS.
Well suited for microservices architecture but can be a bit costly if less number of microservices or monolithic architecture hosted to be hosted on containers. Use of hybrid cluster instances also works well using both normal and fargate instances. Also the integration of audit and diagnostic logs of master nodes helps to reduce the unwanted access related issues.
Well Integrated - As with the majority of AWS services, ECS works will with any other AWS product (Route 53, CloudWatch, IAM, etc).
Easy to get started with - It is easy to get started building just about anything in AWS and using ECS is no exception to this rule. Be careful though -- AWS lets you do/build anything in any way you could think of and allowing yourself to shoot yourself in the foot is no exception.
The user interface sometimes seem to be confusing and cumbersome. It can be improved so that people can understand clearly which section to go for which functionality.
When a container fails, the error logs are not readily available on the ECS console. If it can be provided it would be easier to debug from there itself instead of going to our log manager.
Sometimes the old EC2 containers become stale and need to be restarted manually. There should be a notification for such scenarios. We have mostly been finding it out on our own and then fixing it by manually restarting EC2 instances.
If this could be proactively monitored and notified, it would be great.
Aside from some ECS-specific terms to learn at first, learning & starting to use ECS is relatively straightforward. AWS docs on the topic are also of high quality, with sound & relevant examples to follow. Troubleshooting container issues is also a breeze thanks to CloudWatch integration & helpful error messages on the AWS console.
Support is relatively good, although the documentation sometimes is lacking, as well as outdated in our experience, especially when we initiated the process of using this service. But once we found how to assemble things, we haven't really required support from anyone at AWS, the service works without problems so we haven't had the need to contact support, which speaks well of how ECS is built.
AWS Elastic Beanstalk is a good beginner level orchestration service but lacks container management and scaling capabilities. EC2 is again not a Managed cloud service. It is like just renting a computer on cloud and then managing it on our own. Compared to these ECS is a comprehensive solution that provides management, scaling, containerization and other service connectivity out of the box.
It feels like AWS is behind the EKS race, the only advantage I'm able to see right now is the support of IPv6, however, trying to promote AWS alternatives that are different from the market and more like a vendor locking solutions like ECS/Fargate have kept AWS behind and focusing on the wrong things. EKS needs to really improve its integration with the Kubernetes ecosystem and have an enterprise solution for monitoring, backups, and service mesh.
We run 8 web applications (demo instances) on a single machine. At a particular time, no more than 3 applications run simultaneously. So, we keep only required containers up. This helps us to provision small EC2 machines without compromising performance.
Overall Amazon ECS helps to have less number of dedicated machines as more than one solution can be deployed on a single instance. This reduces costs a lot.
Migrating all our workloads from ec2 VMs to containers running in Kubernetes has been a huge improvement for the management and resilience of our Infrastructure.
EKS Upgrade process to a new version seems to be taking very long ....
EKS creation time usually takes over 10 minutes in us-east-1, we would like faster creation times to be under 5 minutes.
