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.
