Infrastructure as a Service (IaaS) - Statistics & Facts

Alongside Software as a Service (SaaS) and Platform as a Service (PaaS), Infrastructure as a Service (IaaS) is one of the core service models of cloud computing. Under the Infrastructure as a Service model, customers (often enterprises rather than individuals) are permitted to provision and access virtualized hardware and resources - such as servers, networks, storage, or virtual machines.
The customer does not hold the responsibility for maintaining or developing those resources, but instead is free to focus on managing the higher level resources, such as the platform or operating system and the necessary software. In this way, customers can pay only for what they consume, while providers are also free to sell unused resources, leading to substantial opportunity for cost-savings and efficiency gains for both sides.

IaaS market size and share

Infrastructure as a Service represented about a quarter of the overall cloud computing market in 2019 and public cloud IaaS revenues are expected to rise significantly over the coming years, from around 44.5 billion U.S. dollars in 2019 to more than 80 billion U.S. dollars by 2022. Cloud infrastructure's overall market share, however, is expected to fall, as it loses some ground to the maturing Platform as a Service (PaaS) market. The largest segment in the overall cloud computing market is, and will continue to be, Software as a Service with more than 100 billion U.S. dollars in annual revenue.

Major IaaS vendors and providers

In the Infrastructure as a Service market, the largest companies by revenue are Amazon (Web Services), Microsoft (Azure), and Google (Compute Engine). The Chinese multinational technology company Alibaba has emerged as the fourth major player in the market in recent years. However, while Amazon is currently the largest vendor of cloud infrastructure by some margin, its hold over the market may lessen as Google and Microsoft make headway, and surveys suggest there are plenty of other companies fighting for a piece of the cloud IaaS market.
The major hardware IT infrastructure providers for the IaaS cloud market are Dell, HPE, Inspur, Cisco, and Lenovo, which represent around 45 percent of the market combined. Original design manufacturers play a major role in the market as well, taking up around one third of the total market.
