Public Cloud

Definition:

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.

Structure:

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.
