The document discusses how MobiX Corp, an e-commerce company in Taiwan, transitioned their infrastructure to use Amazon ECS and containers to address challenges from their rapid growth. As MobiX launched new brands and saw traffic fluctuations, managing servers became difficult. They moved applications into containers and used ECS for automated scaling and deployment. This simplified operations and allowed scaling without adding complexity. ECS task placement strategies helped optimize resource usage across the cluster. MobiX now has a flexible and low cost architecture that can easily expand.

Containers and Docker
A container is a standard unit of software that packages up code and all its
dependencies so the application runs quickly and reliably from one
computing environment to another.1

Containers and Microservices
• Do one thing, really well
• Any app, any language
• Isolated execution environment
• Test and deploy same artifact
• Faster startup

Containers have become the standard for how to ship and run your
application in the cloud.

Manually downloading and launching containers by hand is
inefficient and error prone.

You need container orchestration to help you for expanding your service.
