🧩 1.Where Docker, Kubernetes, AWS Come In

Imagine your app is developed — now you need to package, deploy, and scale it.

🔹 Before Docker/Kubernetes (Traditional Way)

Earlier, deployment was done like this:

• Developers build the app.
• It is deployed on a physical server or VM.
• Setup includes manual installs of dependencies, OS configuration, etc.
• If the app crashes or traffic spikes, you manually increase resources (scale-up).
