Infrastructure as a service (IaaS) is a method of delivering computing, storage, networking and other capabilities over the Internet. IaaS allows companies to use web-based operating systems, applications and storage without having to purchase, manage and support the underlying cloud infrastructure. 

The most popular platforms are explained below: Amazon Web Services (AWS) and Microsoft Azure.
