The document provides an overview of Amazon ECS (Elastic Container Service) and its components, focusing on its role in managing Docker containers in the cloud. Key features include cluster management, task definitions, and service-oriented architecture that simplifies infrastructure complexity. The document includes links to further resources and tutorials related to ECS functionality and deployment.

4. Why are Docker containers all of a sudden
so popular?

5. What is Amazon EC2 Container Service?
Features
● Easily manage clusters for any scale
● Flexible container placement
● Integrated with other AWS services
● Abstract infrastructure’s complexity

6. Why did we build Amazon ECS ?
To make running Docker enabled applications in the cloud “awesome”

7. Key Components
 Cluster: A cluster is a logical grouping of EC2 instances on which ECS tasks are run.
 Task Definition: The task definition is a text file, in JSON format, describing the
containers that together form an application. Task definitions specify various parameters
for the application e.g. container image repositories, ports, storage etc.
 Service: A service is a group of tasks that are created and maintained as instances of a
task definition.
 Tasks and Scheduler: A task is an instance of a task definition, created at runtime on a
container instance within the cluster. The task scheduler is responsible for placing tasks
on container instances across your clusters based on your resource needs.
 Container Agent: The container agent runs on each EC2 instance within an ECS cluster.
The agent sends telemetry data about the instance’s tasks and resource utilization to
Amazon ECS. It will also start and stop tasks based on requests from ECS.
 Image Repository: Amazon ECS downloads container images from container registries,
which may exist within or outside of AWS, such as a accessible private Docker registry or
Docker Hub.
