What is IaaS (Infrastructure as a Service)?

A cloud service model providing virtualized computing resources like servers, storage, and networking over the internet.

IaaS is the most fundamental cloud service model where the provider manages physical hardware, networking, and virtualization while the customer manages operating systems, middleware, and applications. Examples include AWS EC2, Azure Virtual Machines, and Google Compute Engine. IaaS eliminates the need for physical data center management, offers pay-as-you-go pricing, and provides instant scalability. It gives maximum control compared to PaaS and SaaS but requires more operational expertise.
