Before jumping into the AWS ECS pool let us know a bit about Dockers!
What is Docker?
With the help of the technology known as Docker, applications may be automatically deployed as portable containers that can be used in a number of settings. Consider a scenario where we wish to move our application to the cloud. Instead of compiling and relaunching, we would only need to generate a docker image by putting the code in a container and shipping it there.
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
- Enhanced Security
ECS has built-in security; all of the images are stored in a container registry that is only accessible through HTTPS because they are truly encrypted and can only be permitted by identification and management standards.
We can obtain a high density on an EC2 instance thanks to the ability to schedule several containers on the same node.
Since the environment won’t matter because it will be contained inside a container, the programmed will function precisely as it did in the past.
Amazon ECS key features
AWS Fargate is Integrated:
AWS Fargate is integrated with Amazon ECS, you will not have to worry about performing host management, planning, or learning about task segregation safety for containers. If you merely specify your user’s requirements and choose it as your launching option in the terminal or Command Line Interface (CLI) needed to execute the container, Fargate will start taking care of all scaling and architecture.
The omnipresent: Amazon ECS
With AWS ECS, you can administer container tasks with the same Amazon ECS interface and operator tools throughout your container-based operations. This guarantees consistent user engagement across all of your bucket apps. It is made possible via the AWS Systems Manager (SSM) link to seamlessly and safely trust both existing on-premises equipment and the AWS control layer.
By nature, Amazon ECS is secure and isolated. This enables you to swiftly and effectively transition to reality since Amazon ECS naturally connects with the Protection, Identification, Governance, and Accountability technologies you currently trust. When designing your apps, you may achieve a high degree of isolation by granting each container certain privileges. Deploy the applications whilst maintaining the high security requirements and compliance.

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.
