What is Cloud Computing?

The delivery of computing services over the internet, including servers, storage, databases, and software on demand.

Cloud computing provides on-demand access to shared computing resources without owning physical hardware. The three main service models are IaaS (Infrastructure — virtual machines), PaaS (Platform — managed runtime), and SaaS (Software — applications).

Major providers include AWS (Amazon), Azure (Microsoft), and GCP (Google). Benefits include scalability, pay-per-use pricing, global reach, and reduced operational overhead. Deployment models include public, private, hybrid, and multi-cloud.
