AWS ECS Anywhere

ECS Anywhere is an extension of AWS Elastic Container Service (ECS) that allows you to run and manage containers on your own infrastructure alongside AWS services. It enables you to deploy and manage ECS tasks on your on-premises servers, edge locations, or other cloud providers. In this blog post, we will explore ECS Anywhere, understand its architecture, and provide code examples to demonstrate how it works.

ECS Anywhere Architecture:

The architecture of ECS Anywhere consists of several key components that work together to enable container management on your infrastructure:

  1. ECS Anywhere Agent: The ECS Anywhere Agent is a lightweight software component that runs on your on-premises servers or edge devices. It acts as a bridge between your infrastructure and the ECS control plane in AWS. The agent is responsible for registering the instance with the ECS service, managing container lifecycle events, and reporting status and resource utilization to AWS.
  2. ECS Control Plane: The ECS control plane is the centralized management service provided by AWS. It handles tasks such as scheduling containers, managing cluster resources, and maintaining desired task states. The control plane interacts with ECS Anywhere agents to orchestrate container deployments and monitor their status.
  3. Amazon Elastic Container Registry (ECR): ECR is a fully managed container registry provided by AWS. It stores container images securely and integrates seamlessly with ECS. You can push your container images to ECR and then use them in your ECS Anywhere tasks.
  4. Networking and Load Balancing: ECS Anywhere leverages your existing networking infrastructure. You can use your on-premises networking components such as load balancers, firewalls, and VPNs to manage traffic flow to and from your ECS Anywhere containers.

Code Examples:


  1. Registering an ECS Anywhere Instance: To register an ECS Anywhere instance with the ECS control plane, you need to install and configure the ECS Anywhere agent on your server. Here’s an example of using the AWS Command Line Interface (CLI) to register an instance:
aws ecs create-registration-token --region <your-region>

# Take note of the registration token provided

# Install and configure the ECS Anywhere agent
sudo amazon-ecs-agent --register <registration-token> --cluster <cluster-name> --region <your-region>
  1. Defining an ECS Task Definition: A task definition is a blueprint that describes how a container should be run within an ECS cluster. Here’s an example of a task definition JSON file:
  "family": "my-task-definition",
  "containerDefinitions": [
      "name": "my-container",
      "image": "&lt;your-container-image&gt;",
      "cpu": 256,
      "memory": 512,
      "essential": true,
      "portMappings": [
          "containerPort": 80,
          "hostPort": 80
      "logConfiguration": {
        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "/ecs/my-container",
          "awslogs-region": "&lt;your-region&gt;",
          "awslogs-stream-prefix": "ecs"
  1. Launching an ECS Anywhere Task: Once the ECS Anywhere instance is registered and the task definition is defined, you can launch the task on your infrastructure. Here’s an example using the AWS CLI:
aws ecs run-task --cluster <cluster-name> --region <your-region> --task-definition <task-definition-family>:<task-definition-revision>
  1. Viewing Task Logs: You can view the logs generated by your ECS Anywhere tasks using CloudWatch Logs. The log configuration in the task definition specifies the log group and stream to which the logs are sent. Here’s an example of viewing logs using the AWS CLI:
aws logs describe-log-streams --log-group-name /ecs/my-container --region <your-region>
aws logs get-log-events --log-group-name /ecs/my-container --log-stream-name <log-stream-name> --region <your-region>

Benefits of ECS Anywhere:
  • Flexibility: ECS Anywhere allows you to run containers on your own infrastructure, giving you the flexibility to choose where your workloads are deployed. It enables hybrid cloud and edge computing scenarios.
  • Consistency: By using ECS Anywhere alongside AWS ECS, you can achieve consistent deployment and management experience across your hybrid environment. This simplifies the management of containerized applications.
  • Security and Compliance: ECS Anywhere leverages AWS security features such as IAM roles, encryption, and VPC networking. It enables you to maintain security and compliance standards for your container workloads.

Risks of ECS Anywhere:
  • Infrastructure Complexity: Running containers on your own infrastructure requires managing and maintaining the underlying infrastructure, including servers, networking, and storage. This can introduce additional complexity and overhead.
  • Connectivity and Latency: ECS Anywhere relies on network connectivity between your infrastructure and the ECS control plane in AWS. Issues with network connectivity or high latency can impact the performance and availability of your container workloads.
  • Operational Overhead: Deploying and managing containers on your own infrastructure requires additional operational overhead compared to fully managed services. It involves tasks such as patching, scaling, and monitoring your infrastructure components.

In conclusion, ECS Anywhere brings the power of AWS ECS to your own infrastructure, enabling you to run and manage containers on-premises or at the edge. By understanding its architecture, using code examples, and considering the benefits and risks, you can make informed decisions about adopting ECS Anywhere and leverage its capabilities to deploy and manage containerized applications effectively.
