# PaaS Advantages over IaaS

> Chapter 61 of the Courseiva AZ-900 curriculum — https://courseiva.com/learn/az-900/paas-advantages

**Official objective:** 1.2 — Cloud Concepts

## Introduction

Chapter on PaaS advantages. AZ-900 tests under 1.2.

## Why Rent Instead of Build

Building a house takes effort; renting lets you move in quickly. PaaS is similar: pre-built platform lets you focus on your application, not infrastructure.

## Core explanation

PaaS advantages: no infrastructure management, faster time-to-value, managed scaling. Tradeoff: less control over underlying platform.

## Real-world context

Developers deploy to App Service; Azure handles OS, scaling, patching.

## Exam focus

Objective 1.2 expects understanding of PaaS benefits vs. IaaS.

## Step by step

1. **Confirm PaaS fit** — Is your workload compatible with managed platform?
2. **Deploy to PaaS** — Application is deployed to managed platform.
3. **Focus on application** — Team focuses on code, not infrastructure.

## Key takeaways

- PaaS reduces infrastructure management burden.
- Faster time-to-value for applications.
- Tradeoff: less control than IaaS.

## FAQ

**What are PaaS advantages over IaaS?**
