Your cluster is configured to run in a container environment, making the container the standard system with everything your application needs to run. Services are created via task definitions they run and maintain the needed number of tasks in parallel.Ĭontainers and images are synonymous with their counterparts in Docker. Services, on the other hand, are used to run and/or deploy multiple containers that can have advanced features like load balancing. However, if you want to run and/or deploy a single container without advanced features like load balancing etc., you would use a task. Task definitions can be used to define multiple containers. You can run a task definition as a task or service, depending on your preference. In essence, definitions control the deployment type. Task definitions come in handy when you need to specify which Docker image should be used by a Docker container, the amount of memory to be provisioned for the container, the launch type to adopt, the network and security group configurations, the commands to run, etc. You can use the ECS instance menu to scale your cluster up or down, or even delete it when you don’t need it anymore. Or you can have the clusters based on operating systems-e.g., a Linux cluster for Linux containers and a Windows cluster for Windows containers. This means that for operations, you can create a Production cluster, a Testing cluster, and a Development cluster. You can deploy multiple clusters if you see the need. The type of cluster you configure determines the type of containers you can run in it. You can deploy containers using task definitions by first configuring a cluster. Let’s look at each briefly to gain a better understanding of how Amazon ECS works.ĮCS clusters are logical units of core services or tasks. To further understand ECS, it’s essential to understand the components involved in deploying a service with ECS. You can also scale numerous containers with just a single click, then collate logs about the container instance to Amazon CloudWatch.ĮCS provides the underlying infrastructure to create task definitions for your tasks and services however, you still have to select a launch type that will handle running, stopping, and deploying your tasks and services. You can use it to deploy containers from your local environment via Docker and provision access to those containers from anywhere, resulting in zero downtime and no complicated configurations. What is Amazon ECS?ĮCS is highly scalable and powerful for orchestrating containers that are run on Docker. In this article, we’ll look at how these two launch types compare and explore how to start using them. With ECS, you can deploy containers either on a cluster of Amazon EC2 instances or on AWS Fargate, a serverless computing engine for containers. Amazon Elastic Container Service (ECS) is a fully managed container orchestration service that enables users to easily run, manage and scale containers on AWS.
