This document discusses containers and Amazon ECS. It provides an overview of containers and their benefits like portability and efficiency. It then describes Amazon ECS as a highly scalable and performant container management service that supports Docker containers. It discusses how ECS runs applications on a managed cluster of EC2 instances using tasks, services, and scheduling. It also outlines some key benefits of ECS like being fully managed, integration with other AWS services, and application load balancing. Finally, it provides examples of commands to create an ECS cluster, register a task definition, and create a service to run tasks.

8. Containers are natural for microservices
Simple to model
Any app, any language
Image is the version
Test and deploy same artifact
Stateless servers decrease change risk

11. Amazon ECS

12. Amazon EC2 Container Service (ECS) is a highly
scalable, high performance container management
service that supports Docker containers and allows you
to easily run applications on a managed cluster of
Amazon EC2 instances.

21. Benefits

22. Amazon ECS benefits
• Fully managed elastic service – You don’t
need to run anything, and the service scales as
your microservices architecture grows
• Shared state optimistic scheduling
• Deep Integration With Other AWS Services
• Application Load Balancing
• Amazon Elastic Block Store
• Amazon Virtual Private Cloud
• Amazon CloudWatch
• AWS Identify and Access Management
• AWS CloudTrail

23. Routing via Application Load Balancer
Path-based routing
Allows you to define rules that route traffic to different target groups based on the path of a URL.
e.g example.com/test , example.com/test/test1
Dynamic Port Mapping
Provides the ability to load-balance across multiple ports on the same Amazon EC2 instance. This functionality
specifically targets the use of containers and is integrated into Amazon ECS.
HTTP/2
WebSockets
Detailed Logging

24. Deploying Containers on ECS – Choose a
Scheduler
Batch Jobs
ECS task scheduler
Run tasks once
Batch jobs
RunTask (random)
StartTask (placed)
Long-Running Apps
ECS service scheduler
Health management
Scale-up and scale-down
AZ aware
Grouped containers

25. Running services

26. Create cluster
$ aws ecs create-cluster --cluster-name "my_cluster"

27. Register task definition
$ aws ecs register-task-definition --cli-input-json
file://task-defintion.json

28. Task definition
{
"taskDefinition": {
"status": "INACTIVE",
"family": "curler",
"volumes": [],
"taskDefinitionArn": "arn:aws:ecs:us-west-2:<aws_account_id>:task-definition/curler:1",
"containerDefinitions": [
{
"environment": [],
"name": "curler",
"mountPoints": [],
"image": "curl:latest",
"cpu": 100,
"portMappings": [],
"entryPoint": [],
"memory": 256,
"command": [
"curl -v http://example.com/"
],
"essential": true,
"volumesFrom": []
}
],
"revision": 1
}
}

29. Create service
