IaaS, PaaS, SaaS — Still Confused? Let's Make It Simple.

You’ve heard the terms.

But what do they really mean in plain language?

Here’s a quick breakdown:

IaaS (Infrastructure as a Service)

You manage the app and the OS.

The cloud gives you the infrastructure.

Example: AWS EC2

PaaS (Platform as a Service)Just focus on your app.

The cloud takes care of everything else — OS, servers, runtime.

Example: Google App Engine

SaaS (Software as a Service)You just use it.

Everything is ready to go.

No setup, no maintenance.

Example: Gmail, Zoom

When to choose what?

Need more control? → IaaS

Just want to build apps? → PaaS

Want it fully ready? → SaaS

Simple. Clear. Cloud made easy.
