Infrastructure as a Service (IaaS) adoption is spreading at a rapid pace. According to Gartner’s findings, the IaaS market has been growing by more than 40 percent per annum since 2011, with revenues expected to reach $34.6 billion in 2017. Looking ahead, the market is again poised to more than double in size and reach $71.6 billion in revenues by 2020. Gartner estimates that by then, IaaS providers will deploy the overwhelming majority of all virtual machines (VMs) as more organisations apply a “cloud-first” strategy.
IaaS offers a shared and highly scalable resource pool that can be adjusted on demand. With full control of the allocated computing power and storage, the operating system, middleware and applications, users can commission and decommission IT resources at a blink of an eye, following a pay-per-use model.
