Welcome to containers on AWS! Imagine if you could package your application with everything it needs to run—code, runtime, and system tools—and then deploy it anywhere instantly. That's exactly what containers do.

What's one challenge you've faced when trying to move software from one computer to another?
The main benefit of containers is that they solve the classic "it works on my machine" problem. By bundling the application and its dependencies together, a container ensures that the application runs the same way everywhere, from a developer's laptop to production servers.

How does this consistency help teams collaborate more effectively?
How do containers compare to virtual servers (VMs)? While a VM virtualizes the hardware and includes a full guest operating system, containers virtualize the operating system itself. They share the host OS, making them much more lightweight.
Engagement Message
Why would running more applications on the same hardware save money?
Because containers are so lightweight, they start up much faster than VMs. This allows for rapid scaling, where you can launch hundreds of new containers in seconds to meet a sudden spike in demand.

What kind of application would benefit from extremely fast startup times?
AWS offers services to help you run and manage your containers. A container orchestrator is a tool that automates the deployment, management, scaling, and networking of containers.
This removes much of the operational burden of running containerized applications at scale.
