Infrastructure as a Service (IaaS) is a cloud computing model in which a provider delivers computing resources, including servers, storage, and networking, as a service over the internet. In an IaaS model, users can rent virtualized computing resources on demand, paying only for what they use.

With IaaS, users have complete control over the underlying infrastructure, including the operating system, applications, and other software components. They can configure the infrastructure as they see fit, scaling resources up or down as needed, and pay only for the resources they use.

IaaS is commonly used for a variety of purposes, including hosting websites and web applications, running databases, and providing backup and disaster recovery services. IaaS can also be used to build and run complex applications that require a high degree of control over the underlying infrastructure.

One of the key advantages of IaaS is its flexibility and scalability. Users can quickly provision new resources as needed, without having to worry about purchasing, configuring, and managing physical hardware. This allows organizations to respond more quickly to changing business requirements and to scale their infrastructure up or down as needed to meet demand.

Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and IBM Cloud.
