Amazon Elastic Container Service (ECS) is a fully managed container orchestration service that enables you to run and scale containerized applications on AWS. ECS supports both EC2-backed clusters and serverless container clusters via AWS Fargate, allowing you to choose the level of infrastructure management you need. It handles container scheduling, placement, and scaling, making it easier to deploy and manage containers at scale. [Source]
Amazon ECS is widely adopted, with over 2.25 billion tasks launched every week, tens of thousands of API requests served per second, and operations in 30 AWS regions across 6 continents. According to Amazon, 65% of all new AWS container customers use ECS. [Source]
The main components of Amazon ECS are clusters (logical groupings of tasks, services, and container instances), container instances (EC2 instances running the ECS agent), tasks and task definitions (blueprints for running containers), and ECS services (which maintain a specified number of running tasks). These components work together to orchestrate and scale containerized workloads. [Source]
The three layers of AWS ECS are: 1) Provisioning Layer (using tools like AWS CLI, CloudFormation, CDK, or Terraform to provision clusters), 2) Controller Layer (the container scheduler for placement, lifecycle management, and auto-scaling), and 3) Capacity Layer (supporting EC2, Fargate, ECS Anywhere, and AWS Outposts for flexible deployment options). [Source]
ECS is Amazon's native container orchestration service, offering a balance between control and automation. EC2 provides maximum flexibility and control but requires manual management. EKS is a managed Kubernetes service. Fargate is serverless, abstracting infrastructure management, while Lambda is fully serverless with the lowest management overhead, focusing only on code deployment and triggers. [Source]
EC2 launch type requires managing instances and clusters, offers high control, and is cost-effective for predictable workloads but involves more operational overhead. Fargate is serverless, with AWS managing the infrastructure, offering simplified setup and automatic scaling, ideal for unpredictable workloads and reducing operational overhead. [Source]
ECS clusters are logical groupings of tasks, services, and container instances. They help organize and segregate resources, allowing you to manage multiple environments or teams within a single AWS account. Clusters can use EC2, Fargate, or other capacity providers. [Source]
Container instances are EC2 instances running the ECS agent and registered with a cluster. They provide the compute capacity for running ECS tasks when using the EC2 launch type. ECS places tasks on these instances based on resource requirements and availability. [Source]
ECS tasks are running instances of a task definition, which acts as a blueprint specifying container images, resources, and configuration. Task definitions allow you to version and manage how containers are run in ECS. [Source]
ECS services ensure that a specified number of task instances are always running. If a task fails, the ECS service scheduler automatically launches a replacement, maintaining the desired state and ensuring high availability. [Source]
You can provision ECS clusters using the AWS CLI, Infrastructure as Code (IaC) tools like AWS CloudFormation, AWS Cloud Development Kit (CDK), and Terraform. These tools support different development workflows and operational requirements. [Source]
ECS Anywhere allows you to run ECS tasks on external or on-premises environments, while AWS Outposts extends AWS infrastructure and services to your data center for a consistent hybrid experience. [Source]
Teams managing ECS applications often face challenges such as managing code versions, compute profiles, scaling for seasonality, and ensuring application performance and reliability. These require careful configuration and monitoring. [Source]
Fargate abstracts away server and infrastructure management, allowing you to focus on container configuration and application scaling. It provides automatic security updates, restricted access, secure networking, and compliance with various standards, reducing operational overhead compared to EC2. [Source]
EC2 can be more cost-effective for predictable workloads using reserved or spot instances, but involves more management overhead. Fargate generally has higher per-resource costs but charges only for resources used, with simpler pricing and less operational overhead. AWS notes that system administration, security, and scaling costs should also be considered. [Source]
With EC2, you have more control over infrastructure security but must manage updates and patches. Fargate provides automatic security updates, isolated environments, and compliance with various standards, reducing the security management burden. [Source]
EC2 is best for applications with specific compute requirements and large-scale, steady-state workloads. Fargate is ideal for unpredictable workloads and applications where ease of deployment and minimal operational overhead are priorities. [Source]
ECS supports hybrid and multi-cloud environments through ECS Anywhere (for on-premises and external environments) and AWS Outposts (for extending AWS infrastructure to your data center). This flexibility allows you to run containers wherever your business needs them. [Source]

In this post we'll take a look at ECS vs other Amazon Compute models and some key concepts in Amazon ECS.
ECS is a widely used container platform; here are the numbers previously shared by Amazon about ECS at re:Invent:
Amazon Web Services (AWS) operates on a shared responsibility model, where the cloud service provider, Amazon, manages certain components of the cloud infrastructure, while users are responsible for managing other specific aspects. The degree of user involvement varies based on the compute model selected. Here, we explore four of Amazon's compute models, ranked from the most to the least user effort required.
The table below covers what AWS and you are expected to manage in each of the four models:
So if you look across all these compute models, they all expect development teams to still manage a number of tasks. Questions you are faced with can include:
So there are a lot of challenges that application teams face when they manage their applications.
Amazon Elastic Container Service (ECS) is designed to facilitate scalable and efficient container orchestration. Here's a brief overview of its three core layers:
Amazon Elastic Container Service (ECS) offers a powerful solution for orchestrating containerized tasks and services. To grasp its core concepts and functionalities, let's delve into the fundamental components that make up ECS:
As shown below, ECS tasks are deployed as Services that can be horizontally scaled. And if it's EC2-based you deploy it on a cluster to access sufficient EC2 capacity. If it's Fargate, it's simpler - Fargate resources are used, and you don’t need to worry about the additional complications of EC2.
When choosing a launch type for deploying applications on Amazon Elastic Container Service (ECS), it's crucial to understand the differences between the available options—EC2 and Fargate. EC2 provides granular control over your instances and is cost-effective for predictable workloads, requiring manual setup and scaling. In contrast, Fargate offers a simplified, serverless experience with automated scaling, making it ideal for unpredictable workloads and minimizing operational overhead.
Below is a detailed comparison table that lays out these differences, helping you decide which launch type aligns best with your specific application needs and operational strategy.
AWS notes that while the headline costs of Fargate are more than EC2, there are less obvious costs to consider in deciding on the best model including system administration, security and compliance and scaling as shown below.
Feature | EC2 Launch Type | Fargate Launch Type |
|---|---|---|
Management | Requires managing instances and clusters. | Serverless; AWS manages the infrastructure. |
Control | High control over server types, configurations, and scaling. | Limited control over the computing environment. |
Cost | Cost can be lower for predictable workloads using reserved or spot instances. Charges are based on EC2 instances and EBS volumes used, billed per second with a minimum of one minute. | Generally higher per-resource cost, but only pay for resources actually used (vCPU and memory). Charges are per second with a one-minute minimum. |
Pricing Complexity | More complex with multiple instance pricing options (On-Demand, Reserved, Spot). | Simpler, based on resource usage (vCPU and memory). |
Security | More control over infrastructure to implement security measures, but requires more management overhead to keep EC2 instances secure and patched. | Workloads run in isolated environments with automatic security updates, restricted access, secure networking, and compliance with various standards. |
Setup and Scalability | More complex setup with manual scaling required. | Simplified setup; automatic scaling managed by AWS. |
Use Case Flexibility | Better for specific compute requirements and large-scale, steady-state applications. | Ideal for unpredictable workloads and applications where ease of deployment is prioritized. |
Operational Overhead | Higher, due to the need for instance management and optimization. | Lower, as there is no need to manage servers or clusters. |
