Understanding Cloud Service Models: IaaS, PaaS, SaaS

Cloud computing offers services in three main models: IaaS, PaaS, and SaaS, each serving different business and technical needs.

🧱 1. IaaS – Infrastructure as a Service

IaaS provides virtualized computing resources over the internet. You rent servers, storage, and networking infrastructure but manage your own applications and data.

Examples: AWS EC2, Microsoft Azure VM, Google Compute Engine

Use Case: Hosting websites, custom software, data storage

You Manage: OS, apps, runtime

Provider Manages: Hardware, virtualization, networking

🧰 2. PaaS – Platform as a Service

PaaS offers a ready-to-use platform to develop, test, and deploy applications. It abstracts infrastructure, letting developers focus on coding.

Examples: Google App Engine, Heroku, Azure App Services

Use Case: Web or mobile app development

You Manage: Applications and data

Provider Manages: OS, runtime, servers, scalability

📦 3. SaaS – Software as a Service

SaaS delivers fully functional software over the web. Users don’t worry about installation, updates, or maintenance.
