IaaS – Infrastructure as a Service
PaaS – Platform as a Service
SaaS- Software as a Service
Lets analyse the difference between each of them with real life analogy.
| Model | What You Get | What You Manage | Example | Simple Analogy |
|---|---|---|---|---|
| IaaS | Servers, Storage, Networking | OS, apps, data | AWS , Microsoft Azure, Google Cloud | You buy wheat flour and cook chapati + vegetables yourself (full control, full effort). |
| PaaS | Infrastructure + Platform (OS, tools, DB) | Only your apps & data | Power Apps, Zoho Creator | You get frozen paratha and frozen cooked vegetables, you just heat them up (some control, less effort). |
| SaaS | Complete application (ready-to-use software) | Just use the app | Gmail, Drop Box, NetFlix,Office 365 and Salesforce | You order chapati and vegetables from a restaurant and simply eat (no control, least effort). |
