Using containers has become a common practice across many workloads. In this session we will cover the benefits of using containers, focusing on the value of using container orchestrators in managing containers at scale. The session will provide an insight on commonly used container orchestrators on AWS (Amazon ECS , Amazon EKS). The session goal is to provide valuable insights to support the process of choosing a container orchestrator on AWS and will include a demo using AWS Fargate

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
