Introduction
Cloud computing delivers IT resources (servers, storage, databases, apps) over the internet with pay-as-you-go pricing instead of owning physical data centers.
Why This Topic Matters
IT Vizag uses Firebase, Vercel, and similar cloud services. Interviews ask “what is cloud?” even for junior roles.
Real-Life Example
Your LMS runs on hosted platform — no server in Vizag office, scales when more students enroll.
How it fits together
On-premise: you own hardware. Cloud: provider owns hardware; you rent capacity. Benefits: scale, speed, global reach.
Your action
- List apps you use that are “in the cloud”.
- Contrast with software installed only on one PC.
- Note monthly vs capital expense model.
Expected Output
Explain cloud to a non-technical friend in 3 sentences.
Practice Problems

Explain how "What Is Cloud Computing?" helps a B.Tech fresher in Vizag or remote IT roles.
Mini Assignment
Apply one concrete idea from "What Is Cloud Computing?" this week — notes, a mock task, or with a study partner. Then open the resume builder (/career/resume) and add one bullet under Experience or Projects describing what you did.
Lesson Summary
Cloud = someone else’s data center, billed as you use it.
