EC2 Container Service Benefits

Easily Manage Clusters for Any Scale

Nothing to run

Complete state

Control and monitoring

Scale

Flexible Container Placement

Applications

Batch jobs

Multiple schedulers

Designed for use with other AWS services

Elastic Load Balancing

Amazon Elastic Block Store

Amazon Virtual Private Cloud

AWS Identity and Access Management

AWS CloudTrail

Extensible

Comprehensive APIs

Open source agent

Custom schedulers

Common Patterns

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.”

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.”
