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

What is Amazon ECS?
Amazon EC2 Container Service (ECS) is a highly scalable,
high performance container management service. You
can use Amazon ECS to schedule the placement of
containers across your cluster. You can also integrate your
own scheduler or third-party scheduler to meet business
or application specific requirements.

Update Service (cont.)
Specify a deployment configuration for your service:
• minimumHealthyPercent: lower limit (as a percentage of
the service's desiredCount) of the number of running
tasks that must remain running in a service during a
deployment.
• maximumPercent: upper limit (as a percentage of the
service's desiredCount) of the number of running tasks
that can be running in a service during a deployment.
Update Service (cont.)
Deploy using the least space: minimumHealthyPercent =
50%, maximumPercent = 100%
Update Service (cont.)
Deploy quickly without reducing service capacity:
minimumHealthyPercent = 100%, maximumPercent =
200%
