Infrastructure as a Service (IaaS) is a cloud computing service that provides the necessary computing, storage, and network resources on a pay-as-you-go basis. IaaS is one of the four types of cloud services, the other three being software as a service (SaaS), platform as a service (PaaS), and serverless.

Migrating your organization's infrastructure to IaaS can reduce maintenance work in local data centers, save hardware costs, and gain real-time business insights. IaaS allows you to flexibly scale up or down IT resources based on demand. They can also quickly provision new applications and improve the reliability of the underlying infrastructure.
