Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. With IaaS, businesses can rent virtualized hardware resources, such as storage, networking, and servers, on a pay-as-you-go basis. This allows businesses to scale their IT infrastructure up or down as needed, without the need for large upfront investments in physical hardware.
In this article, we will break down the basics of IaaS, including what it is, how it works, and the benefits it offers to businesses. We will also address some frequently asked questions about IaaS.
