Containers are natural for microservices

Simple to model

Any app, any language

Test & deploy same artifact

Stateless servers decrease change risk

Amazon ECS

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.

Benefits

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

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%
