3 Core Cloud Service Models: IaaS, PaaS & SaaS. I’ve explained them in simple steps below. 𝗜𝗔𝗔𝗦 (𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗮𝘀 𝗮 𝗦𝗲𝗿𝘃𝗶𝗰𝗲) (𝘚𝘵𝘦𝘱-𝘣𝘺-𝘚𝘵𝘦𝘱) Gives you raw cloud infrastructure (servers, networks, and storage) to build and control your own environment. 1. Select a cloud provider (AWS, Azure, GCP, etc.). 2. Create and configure virtual servers. 3. Set up network and storage systems. 4. Install the operating system. 5. Add middleware like databases or web servers. 6. Manage system security and apply updates. 7. Monitor performance to optimize usage. 8. Handle load balancing for high traffic. 9. Deploy and manage your own applications. 10. Set up the runtime environment for execution. ✅ 𝗕𝗲𝘀𝘁 𝗳𝗼𝗿: Developers who want full control over infrastructure. ___________________________________ 𝗣𝗔𝗔𝗦 (𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝗮𝘀 𝗮 𝗦𝗲𝗿𝘃𝗶𝗰𝗲) (𝘚𝘵𝘦𝘱-𝘣𝘺-𝘚𝘵𝘦𝘱) Provides a ready-to-use platform where you can focus on writing and deploying code, not managing servers. 1. Choose a PaaS provider (like Heroku or Google App Engine). 2. Write your application code. 3. Push and deploy the code to the platform. 4. The platform automatically provisions runtime resources. 5. Define app configuration using environment variables. 6. Receive automatic platform updates and maintenance. 7. Track app performance via dashboards. 8. Use built-in middleware services (databases, caching, etc.). 9. Auto-scale automatically when traffic grows. 10. Manage dependencies through built-in tools. ✅ 𝗕𝗲𝘀𝘁 𝗳𝗼𝗿: Developers who want to build apps quickly without managing infrastructure. ___________________________________ 𝗦𝗔𝗔𝗦 (𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝗮𝘀 𝗮 𝗦𝗲𝗿𝘃𝗶𝗰𝗲) (𝘚𝘵𝘦𝘱-𝘣𝘺-𝘚𝘵𝘦𝘱) Delivers ready-made software over the internet, you just log in and start using it. 1. Register for a SaaS product or tool. 2. Sign in via web or mobile app. 3. Access and use the core features instantly. 4. Customize or adjust settings as needed. 5. Upload files or manage user data. 6. The provider handles all security and maintenance. 7. Receive automatic feature and version updates. 8. Access built-in analytics and reports. 9. Integrate with other tools if required. 10. Collaborate with teammates in real time. ✅ 𝗕𝗲𝘀𝘁 𝗳𝗼𝗿: End users who want convenience with zero maintenance. In simple: • 𝗜𝗔𝗔𝗦 = You manage everything. • 𝗣𝗔𝗔𝗦 = You manage code only. • 𝗦𝗔𝗔𝗦 = You just use the software. Choose based on your control, speed, and scalability needs. ✅ Repost for others in your network who can benefit from this.
