Amazon Elastic Container Service (ECS)
Amazon Elastic Container Service (ECS) - is a fully managed container orchestration service that allows users to run, stop, and manage Docker containers on a cluster of Amazon EC2 instances. ECS is highly scalable and supports Docker containers, making it easy to deploy, manage, and scale containerized applications.
Key definitions for Amazon Elastic Container Service (ECS):
-
Task Definition
A blueprint that describes how a Docker container should be run. It includes information such as the Docker image to use, CPU and memory requirements, and environment variables.
-
Service
Ensures that your application maintains the desired number of task instances defined in a task definition. It continuously runs and manages these instances, making sure that the specified number of tasks are always operational.
-
Cluster
A logical grouping of EC2 instances or AWS Fargate tasks that ECS uses to run your applications. Clusters can span multiple availability zones within an AWS region.
-
Container Instance
An EC2 instance that is part of an ECS cluster and has the ECS container agent installed.
-
Task
The instantiation of a task definition within a cluster. A task represents a single running container or group of containers.
Service integrates with:
Usage use cases
-
Microservices Architecture.
ECS allows organizations to break their applications into smaller, more manageable services that can be developed, deployed, and scaled independently.
-
Batch Processing.
ECS can be used to run batch processing tasks, making it easier to handle workloads that require processing large volumes of data.
-
Web Applications.
Deploy and manage scalable web applications using ECS, ensuring high availability and easy maintenance.
-
CI/CD Pipelines.
Integrate ECS with CI/CD tools like AWS CodePipeline and CodeBuild to automate the build, test, and deployment processes.
-
Hybrid Deployments.
ECS supports both EC2 and Fargate, providing flexibility to run containers either on a serverless infrastructure or on managed EC2 instances.
