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.”
