Understanding Infrastructure as a Service (IaaS): A Case Study of Amazon Web Services (AWS)

Infrastructure as a Service (IaaS) is a cloud computing model where third party providers host and manage core IT infrastructure, delivered via the internet. Using Amazon EC2, businesses access computing resources through management consoles and API for self service provisioning. This approach allows IT teams direct control over virtual infrastructure without owning physical hardware. Consequently, organizations avoid purchasing and maintaining physical servers, networking equipment, and storage devices, which significantly reduces capital expenditure and operational requirements.
