Cloud hosting
🏠The everyday picture
A serviced business park (Choosing Your Tools, Lesson 7): rooms, storage, security and extra space on demand, billed by use.
📘What it really is
-
Cloud platforms (AWS, Google Cloud, Microsoft Azure) rent computing in small, flexible pieces: virtual servers, managed databases, file storage, serverless functions and more.
-
You can add or remove capacity in minutes, and often pay by the hour or by use.
-
App platforms (Vercel, Netlify, Render, Railway) sit on top of the cloud and handle servers for you: you connect a Git repository and they build and deploy. Your test site uses a similar idea through Hostinger's Git deployment.
-
Serverless doesn't mean no servers. It means you don't manage them: your code runs only when called.
- Watch out for costs: set budget alerts from day one.
🖱️Try it
Think about the auto-deploy you set up for test.prolearners.in: a push to GitHub, and the site updates itself. Write down which parts of that process you manage, and which the host manages.
