Why Cloud service models (IaaS, PaaS, SaaS) in GCP? - Purpose & Use Cases

The Big Idea

What if you could build powerful apps without ever touching a server?

The Scenario

Imagine you want to build a website. You buy a physical server, install the operating system, set up the web server software, and manage everything yourself.

The Problem

This manual way is slow and tricky. You spend hours fixing hardware issues, updating software, and worrying about security. If traffic spikes, your server might crash, and scaling up means buying more hardware.

The Solution

Cloud service models like IaaS, PaaS, and SaaS let you focus on what matters. They handle the heavy lifting of servers, software, and maintenance, so you can build and run your app faster and easier.

Before vs After

✗ Before

Buy server -> Install OS -> Setup software -> Manage updates

✓ After

Choose IaaS/PaaS/SaaS -> Deploy app -> Let cloud handle the rest

What It Enables

It enables you to launch and grow applications quickly without worrying about the complex infrastructure behind them.

Real Life Example

A startup uses PaaS to build their app without managing servers, saving time and money while focusing on features their users love.

Key Takeaways

Manual infrastructure is slow and error-prone.

Cloud service models simplify building and running apps.

You can focus on your app, not the hardware or software setup.
