The world of cloud computing can feel like a buzzword jungle — full of acronyms and tech-speak that’s easy to get lost in. Among the most common (and confusing) are SaaS, PaaS, and IaaS. But don’t worry — we’re here to break it all down in plain language. Let’s get started. 1. SaaS – Software as a Service Think: Ready-to-use apps in your browser.

IaaS – Infrastructure as a Service Think: Virtual hardware — servers, storage, and networks. IaaS provides the basic building blocks for cloud IT. You get access to virtual machines, storage, and networks — and you’re responsible for managing everything from the OS up. It’s powerful and flexible, but you need to know what you’re doing. 📌 Real-life Examples: ✅ You use IaaS when: 📊 Quick Comparison Feature SaaS PaaS IaaS Users End users Developers IT administrators You manage Nothing Apps & data Everything but hardware Flexibility Low Medium High Examples Gmail, Zoom, Trello Heroku, Google App Engine AWS EC2, Azure VM 🧠 In Summary Each “as-a-service” model gives a different level of control, flexibility, and responsibility. Whether you’re just streaming a show or deploying a complex enterprise system — you’re probably already using one of these cloud models every day.
