What is Infrastructure-as-a-Service (IaaS)?


Infrastructure-as-a-service (IaaS) is a cloud-based service that provides end-users with on-demand virtual IT resources (compute, networking, storage, etc.). In the IaaS model, the cloud provider manages the infrastructure and delivers resources to clients via virtual machines accessible through the Internet.

IaaS is a cost-effective alternative to hosting physical infrastructure in an on-prem data center. The model enables users to scale resources on an as-needed basis, allowing companies to control expenses and ensure optimal performance.
