Before jumping into the AWS ECS pool let us know a bit about Dockers!
What is Docker?
Docker is a technology for automating the deployment of an application as a portable container, allowing it to function well in a variety of contexts. Let’s say we want to migrate our application, in such a case we just need to create a docker image by
packing the code in a docker container and shipping that image to the cloud environment, without the need of compiling and relaunching.

What is AWS?
Amazon Web Service popularly known as AWS is a web server in a cloud that provides a variety of services like compute power, database storage, content delivery, and a lot of other resources so that one can scale business and grow.
What can we do with AWS?
Well, the answer is pretty simple, with AWS we can deploy any application on the cloud which would be available to our end-user; the user can be an internal or even a person on the internet sitting anywhere around the world, we can even create our application inside the cloud as it comprises of all the tools and services required for creation.

What is AWS ECS?
- Amazon Elastic Container Service (Amazon ECS) is a container management service that can quickly launch, exit, and manage docker containers in a cluster.
- It maintains the availability of the application and allows every user to sell containers when necessary.
- It meets the availability of the application: one container hosting your application should be running all the time, to meet that high availability, therefore it becomes important for the container to make sure that the service is running 24/7.
- It does not end here, let’s say suddenly there is an increase in demand, so how do you meet that demand; Amazon ECS makes it a lot easier by automatically scaling the number of containers needed to meet the demand.
- It also schedules the placement of containers across the cluster that can be launched via AWS management console and SDK kits like the Java program and Nodejs Program.
- It’s neither a product nor a feature all by itself; it’s a service that’s dependent on Docker containers. Before the docker container, all the applications used to run on VM or the host or physical machine; were memory bound and even had several server issues.
Why Amazon ECS?
With ECS the services can run seamlessly because ECS manages containers the applications can run in a highly available mode, that is, if something goes wrong then some other container gets found, and then the application runs in that container. There is a very minimal chance of your application going down.
This is one of the reasons why organizations today are using ECS instead of VM or physical machines.

Advantages of ECS
- Improved Security
The security is inbuilt in ECS, we have a container registry where all the images are stored and are only accessible through HTTPS as they are actually encrypted and can only be allowed through identity and management policies.
- Cost Efficient
One can schedule multiple containers on the same node, it allows us to achieve a high density on an EC2 instance.
As the environment is not a concern for containers as it’s going to shut itself inside a docker, and the application will run exactly the way it performed in the past.
Amazon ECS key features
- Security and isolation by design:
Amazon ECS natively integrates with the Security, Identity, Management, and Governance tools you already trust, which helps you get to production quickly and successfully. You are server less by default with AWS Fargate
AWS Fargate is built into Amazon ECS, which means you no longer have to worry about managing servers, handling capacity planning, or gaining knowledge of workload isolation security for containers. Fargate will take care of all scalability and infrastructure if you only state the requirements of your application and select it as your launch type in the console or Command Line Interface (CLI) required to run your containers.
- Amazon ECS Anywhere:
For a consistent user experience across all of your container-based apps, AWS ECS Anywhere enables you to manage your on-premises container workloads using the familiar Amazon ECS console and operator tools across your container-based applications. The AWS Systems Manager (SSM) link ensures that your on-premises hardware and the AWS control plane are automatically and securely trusted.
- Security and isolation by design:
Amazon ECS natively integrates with the Security, Identity, Management, and Governance tools you already trust, which helps you get to production quickly and successfully. By giving each container granular privileges, you may obtain a high level of isolation when developing your applications. Launch your containers while adhering to the security and legal requirements for which AWS has been renowned.
Limitations of AWS ECS
Even though there are a lot of benefits of Amazon ECS, it has some limitations as well:
You can’t alter the instance type or size when hibernation is enabled.
When you hibernate an instance, the data which is stored in the instance is lost.
You can’t hibernate any instance for more than 150 GB of RAM.
Companies using Amazon ECS
The pure cloud video software-as-a-service solution 3dEYE supports practically any internet protocol or network video recorder camera and is hardware independent.
Aerobotics is an agri-tech company operating in 18 countries around the world, in 2018, their data processing infrastructure could not support the data demands needed to increase velocity.
Having adopted Kubernetes, they deployed Fargate for EKS, delivering a completely managed service
AutoDesk has been making software for people who construct and build things in the architecture, construction, engineering, manufacturing, and media industries for the past 35 years.
Amazon ECS deeply integrates with the rest of the AWS platform to provide a secure and easy-to-use solution for running container workloads in the cloud and now on your infrastructure with Amazon ECS Anywhere.
