Docker: Containerization Basics in Cloud Computing
Docker packages application + dependencies in container. Container = lightweight, isolated, reproducible. Works on laptop = works on prod (no "works on my machine").
Dockerfile = recipe. docker build = create image. docker run = create container (instance). Image = blueprint (read-only), Container = instance (running).
Benefits: Consistency, portability, efficiency (smaller than VMs), fast startup. Industry standard for deployment. AWS ECS, Google Cloud Run, Kubernetes all use Docker.
