In the ever-evolving cloud computing landscape, Amazon Web Services (AWS) has been a major player in the market. With a wide range of services, AWS has provided customers with an extensive range of options to meet their application needs. When it comes to container orchestration, AWS offers three leading solutions: AWS ECS, EKS, and Fargate. Let’s discuss how AWS ECS, EKS, and Fargate differ from each other and what you should choose for your business.
What is Amazon ECS?
AWS ECS (Elastic Container Service) is an Amazon Web Services (AWS) offering that provides a managed container platform for deploying, orchestrating, and managing containers. It simplifies the process of running, scaling, and managing applications on containers in the cloud. AWS ECS allows users to deploy, manage, and scale containerized applications across clusters of Amazon EC2 instances.
It provides a secure and reliable platform that is designed to run containers with high availability and scalability. It also provides support for running applications on both Linux and Windows-based containers. AWS ECS supports a variety of container orchestration tools and provides integration with popular container registries, such as Amazon ECR. AWS ECS is also integrated with other AWS services, such as IAM, VPC, and CloudWatch, allowing users to manage and monitor their applications easily.

- Amazon EC2 Container Service (ECS) is a container management service that runs, manages, and scales Docker containers on a cluster of Amazon EC2 instances.
- ECS allows you to define container placement strategies and resource requirements, automate deployments, and configure automatic scaling.
- ECS provides the ability to launch containerized applications quickly and easily and manages them in a highly available and scalable manner.
- ECS connects to a cluster of EC2 instances and deploys Docker containers onto them. Each instance runs an agent communicating with the ECS Control Plane to receive and process requests.
- ECS then schedules containers onto the cluster based on the resource requirements specified in each task definition.
- The ECS Control Plane manages the cluster, including scaling the number of instances needed, provisioning new instances, and scheduling tasks to run on the cluster.
- ECS provides a web-based console for managing clusters, tasks, and services. This console can be used to define task definitions, manage tasks and services, and view cluster performance metrics.
What is Amazon EKS?
AWS EKS (Elastic Kubernetes Service) deploys and manages containerized applications on the AWS cloud. It provides a managed Kubernetes environment, allowing users to quickly and easily deploy Kubernetes clusters to AWS. It allows users to set up and configure Kubernetes clusters with a few clicks or commands.
EKS also provides users with powerful tools for managing and scaling Kubernetes clusters. Through EKS, users can quickly deploy and manage applications on the AWS cloud while taking advantage of AWS’s scalability, security, and reliability.

- AWS EKS is a managed Kubernetes service that makes it easy to deploy and manage Kubernetes clusters in the cloud.
- It enables users to create and manage AWS-hosted Kubernetes clusters without the need to manage individual Kubernetes nodes.
- AWS EKS sits on top of the EC2 Auto Scaling group, which is responsible for creating and managing the EC2 instances that comprise the Kubernetes cluster.
- Each EC2 instance is automatically provisioned with the required software and configuration to join the Kubernetes cluster, including the Kubernetes API server and the Kubernetes node.
- The Kubernetes API server manages and coordinates the Kubernetes nodes.
- The nodes are managed by the EC2 Auto Scaling group, responsible for scaling up or down the number of nodes in the cluster as needed.
- AWS EKS also allows users to easily create, manage easily, and scale Kubernetes clusters using the AWS Management Console or the AWS CLI.
- Additionally, AWS EKS provides access to a wide range of AWS services, such as Amazon ECR for container registry, Amazon S3 for storage, and Amazon VPC for networking.
What is Amazon Fargate?
AWS Fargate is a technology from Amazon Web Services (AWS) that provides container orchestration for applications and services running on the AWS cloud. It allows developers to focus on building and running applications without managing the underlying infrastructure. Fargate makes it easy to deploy and scale applications on the cloud without needing to provision or manage servers.
It provides a serverless compute engine for running containers, which eliminates the need to select server types and sizes and simplifies the process of provisioning and scaling applications. Fargate also supports the scaling of applications based on CPU, memory, and disk usage and allows users to set up automatic scaling policies to ensure that applications are always running at the optimal level.

- Fargate enables users to launch containers with just the CPU and memory requirements without having to provision or manage any virtual machines or clusters.
- It provides a container-optimized environment that can be dynamically scaled up or down based on application load.
- It automatically handles the orchestration and scheduling of containers and can be used with AWS services such as Amazon ECS, Amazon EKS, and AWS Lambda.
- Fargate also integrates with other AWS services, such as Amazon Elastic Container Service (ECS), Amazon Elastic Kubernetes Service (EKS), and AWS Application Load Balancer (ALB). These services provide users with a comprehensive platform for running, deploying, and scaling distributed applications in the cloud.
AWS ECS Vs. EKS Vs. Fargate: The Differences
AWS ECS, EKS, and Fargate are all cloud-based container management services provided by Amazon Web Services (AWS). Here are some key differences between the three:
- ECS is a container orchestration service, while EKS is a Kubernetes orchestration service.
- ECS provides cluster management capabilities, while EKS provides cluster management capabilities via Kubernetes.
- Fargate allows you to focus on your containers without managing the underlying instances, whereas, in ECS and EKS, you have to manage the instances.
- ECS and EKS have more flexibility in terms of networking and scaling options compared to Fargate, which only allows for automatic scaling.
- EKS is generally more suited for larger and more complex applications, while ECS and Fargate are better suited for simple and smaller applications.
- EKS is more expensive than ECS and Fargate since it involves additional costs for running a Kubernetes cluster.
Overall, ECS is the simplest and easiest to use, while EKS and Fargate offer more advanced features and scalability. It ultimately depends on your specific use case and requirements.
AWS ECS Vs. EKS Vs. Fargate: Which One To Choose?
Choosing between AWS ECS, EKS, and Fargate depends on your application’s specific needs and requirements. Here are some general guidelines to help you make a decision:
- If you are already familiar with and want to use Docker containers, and you don’t need the additional features provided by Kubernetes, then ECS may be the best choice for you.
- If you want to use Kubernetes for container orchestration and don’t want to manage the underlying infrastructure, then EKS may be the best choice for you.
- If you want to run containers without managing the underlying instances and don’t need the additional features provided by Kubernetes, then Fargate may be the best choice for you.
- It’s also worth noting that AWS ECS and EKS are both highly customizable, and you can use them in conjunction with other AWS services, such as Elastic Load Balancing, Auto Scaling, and Elastic Block Store. Additionally, ECS and EKS can be integrated with other services and tools like AWS App Mesh, AWS App Runner, etc.
In summary, when choosing between ECS, EKS, and Fargate, it’s essential to consider your use case, the specific requirements of your application, and your team’s expertise. It’s also important to consider the service’s cost and scalability.
