A public cloud is defined as the digital infrastructure and computing resources that are managed by a service provider. Examples of public cloud computing resources include virtual machines, storage, and services, all of which are available for purchase with flexible (e.g., pay as you go and subscription) business models. Such payment options make it possible for customers to access, scale, and utilize resources as needed. Public cloud solutions make it possible for users to save on IT costs, increase their efficiency, and take advantage of advanced technologies without having to invest in long-term IT solutions. Public cloud service providers own and maintain the physical infrastructure, hardware, and software. Users only need to pay for the computing resources that they require. The Public Cloud market refers to the companies that provide these cloud computing resources and services to individuals, businesses, and organizations.
The Public Cloud market is structured into five markets based on the type of service models provided by the companies.
The Infrastructure as a Service (IaaS) market covers the resources and services related to the data center infrastructure.
The Platform as a Service (PaaS) market covers the resources and services related to the virtual environments used for software development.
The Software as a Service market (SaaS) market covers the resources and services related to software applications that can be accessed via a web browser.
The Business Process as a Service (BPaaS) market covers the resources and services related to the various business processes such as finance and accounting, human resources, customer service, and supply chain management, all delivered through the cloud.
The Desktop as a Service (DaaS) market covers the resources and services related to virtual desktop environments, which are accessible from any device with an internet connection.
The public cloud market comprises revenue, revenue change, average spend per employee, and key player market shares as key performance indicators. Only revenues that are generated by primary vendors at the manufacturer price level either directly or through distribution channels (excluding value-added tax) are included, and revenues generated by resellers are excluded. Revenues are generated through both online and offline sales channels and include spending by consumers (B2C), enterprises (B2B) as well as governments (B2G). Detailed definitions of each market can be found on the respective page where the market data is displayed.
Key players of the public cloud market include companies such as Amazon (Amazon web services), Microsoft (Azure), Google (Cloud), and IBM (Cloud).

Cloud computing is one of the hot topics when talking about IT development and groundbreaking industry changes. Cloud computing affects all kinds of business processes and can tackle dynamic and complex needs. Infrastructure as a Service (IaaS) makes it easy to scale up or down physical servers and data center infrastructure. Platform as a Service (PaaS) offers tools in a virtual environment that provide the possibility of developing and running applications. Software as a Service (SaaS) is a third cloud service model for licensing and delivering business applications that are typically accessed via a web browser. Besides purely private and purely public cloud solutions, hybrid cloud and multi-cloud models will play an important role in enterprises’ future cloud strategies.
The data encompasses B2B, B2G, and B2C enterprises. Figures are based on the money spent at manufacturer price level (excluding VAT).
Modeling approach / Market size:
Market sizes are determined through a top-down approach with a bottom-up validation, building on a specific rationale for each market segment. As a basis for evaluating markets, we use annual financial reports of the market-leading companies and reports from our primary research. In addition, we use relevant key market indicators and data from country-specific associations, such as GDP and level of telecommunications infrastructure. This data helps us estimate the market size for each country individually.
In our forecasts, we apply diverse forecasting techniques. The selection of forecasting techniques is based on the behavior of the relevant market. The main drivers are the GDP and the level of digitization.
The data is modeled using current exchange rates. The market is updated twice a year in case market dynamics change. The impact of the COVID-19 pandemic is considered at a country-specific level.
