## What Is IaaS? | Infrastructure as a Service
What Is IaaS? IaaS (Infrastructure as a Service) a cloud computing model that provides virtualized computing resources over the internet. Instead of buying hardware, you rent IT infrastructure—servers, virtual machines, storage, and networks—on a pay-as-you-go basis.

## Why This Matters for Your Business
IaaS lets your business deploy servers in minutes instead of weeks, scale capacity during busy periods, and eliminate the cost of maintaining physical hardware. It's particularly valuable for businesses with fluctuating workloads or those expanding to new locations.
