Amazon Elastic Container Service (Amazon ECS) vs. Mirantis Kubernetes Engine

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.

Docker is great for when you would want to use a VM for any given application, but don't need the overhead of the whole OS. Docker containers use very little computing resources, boot up very quickly, and are very easy to set up. An instance where Docker may not be appropriate would be for an application that requires good security. If in this situation, a true VM would probably be your best bet.

• 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.

• Containerization - allowing multiple micro-services to function together without in-depth orchestration at the VM level.
• Rapid deployment - a developer with appropriate access can simply push to the correct remote and the deploy happens automatically from there
• Decouples provisioning from VM administration - allows containers to be deployed (more) regardless of VM set up.

• 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.

• Docker has a bit of a learning curve, and it takes some time to become familiar with the tooling and syntax. Transitioning an existing architecture to docker can represent a significant investment.
• Docker attempts to provide some level of cross-host container orchestration via swarm, but it falls short of third-party solutions like kubernetes.
• We occasionally run into stability issues when the docker daemon is subjected to high load (many applications starting/stopping frequently). In these cases, docker hangs and we have to restart or replace the node.

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.

Docker's CLI has a lot of options, and they aren't all intuitive. And there are so many tools in the space (Docker Compose, Docker Swarm, etc) that have their own configuration as well. So while there is a lot to learn, most concepts transfer easily and can be learned once and applied across everything.

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.

The community support for Docker is fantastic. There is almost always an answer for any issue I might encounter day-to-day, either on Stack Overflow, a helpful blog post, or the community Slack workspace. I've never come across a problem that I was unable to solve via some searching around in the community.

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.

I have not used any other software as a container management solution. Its containerized apps allow the usage of less memory, thus
they start and shut down very fast. This tool is helping the enterprise
software to work quickly against the changing conditions thus offers great
scaling by simultaneously allowing me to meet the demands, which also leads to
easy implementation of the strategies.

• 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.

Incentivized

• We are able to try things very quickly compared to before. If you need to debug it, changes on X/Y/Z will have an impact on the way your app works, and changing libraries or configurations of the environment easily can improve your development cycles.
• In case someone new arrives, the onboarding is pretty easy thanks to Docker. We have tried many configs and images until we reached a point were we have what we want. We don't have to painfully do that again for every new user. We just send him the image.
