Amazon EC2 Container Service (Amazon ECS) is a new AWS service that makes it easy to run and manage Docker-enabled applications across a cluster of Amazon EC2 instances. Amazon ECS lets you define, schedule, and stop sets of containers. You have access to the state of your resources, making it easy to confirm that tasks are running or view the utilization of EC2 instances in your cluster. This session will describe the benefits of containers, introduce ECS, and demonstrate how to use ECS for your applications.

16. Amazon ECS Benefits

17. Easily manage clusters for any scale
• Nothing to run
• Complete state
• Control and monitoring
• Scale

18. Flexible container placement
• Applications
• Batch jobs
• Multiple schedulers

19. Designed for use with other AWS services
• Elastic Load Balancing
• Amazon Elastic Block Store
• Amazon Virtual Private
Cloud
• AWS Identity and Access
Management (IAM)
• AWS CloudTrail

20. Extensible
• Comprehensive APIs
• Open source agent
• Custom schedulers

21. Common Patterns

22. Pattern 1: Services and applications
• Simple to model
• Micro services
• Blue/green
deployments
Phong Nguyen, Founder at Gilt
Groupe, said, "As we Dockerize
all our services, it is very
important for us to have a
platform that can help us speed
up deployments, automate our
services, and gain greater
efficiencies. The new service
scheduler and ELB integration
make Amazon ECS an excellent
platform for our services.”

23. Pattern 2: Batch jobs
• Share resource pools
• Ideal for bursty jobs
• Spot Instances
“We required a solution on which
we could securely and efficiently
deploy Docker containers to
encapsulate learner
programming assignment
submissions,” said Brennan
Saeta, architect at Coursera. “We
are using Amazon EC2 Container
Service to power our new
programming assignments
infrastructure for next-generation
On-Demand course platform.”
