cloud Introduction to Cloud Computing

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.

Syntax Breakdown

On-premise: you own hardware. Cloud: provider owns hardware; you rent capacity. Benefits: scale, speed, global reach.

Step-by-Step Code Explanation

1. List apps you use that are “in the cloud”. 2. Contrast with software installed only on one PC. 3. Note monthly vs capital expense model.

Expected Output

Explain cloud to a non-technical friend in 3 sentences.
