Cloud service providers and Service Models of Cloud Computing

A cloud service provider is a third-party company that offers a platform, infrastructure, application, or storage services via the cloud (often abbreviated as CSP). Businesses are typically only required to pay for the number of cloud services that they use, which is determined by the needs of the company, in the same way, that a household would pay for a utility like electricity or gas. There are advantages and disadvantages to using cloud service providers (Cloud Computing Benefits: Perfect Cloud Service Provider Choosing Tips, 2022). The three main service models used in cloud computing are as follows:

  1. Software as a service (SaaS): It enables the user to use an entire application that is active on another person's computer. SaaS encourages clients to work in multi-inhabitant settings, which benefits clients by coordinating the results from various applications on cloud computing, according to the state of information technology today. Examples include Google Docs and Office 365. (Ahmad et al., 2022, p.1902).
  2. Platform as a service (PaaS): It is a middleware as a service platform for building and deploying unique applications by developers. Applications are created by developers using web-based tools, which means that the hardware and operating system are provided by a different company. The system is maintained and provided with tools like Java and.NET by the PaaS cloud computing service provider. However, clients are responsible for choosing the applications that run on the platform based on their preferences and using the available tools (Ahmad et al., 2022, p.p. 1902-1903).
  3. Infrastructure as a Service (Iaas): With this model, businesses can lease or rent servers for cloud computing and storage. This allows users to use any operating system or application on the rented servers without having to pay for the servers' upkeep and running costs. IaaS users will be responsible for all computer system security requirements, except for physical security, which is managed by cloud computing providers. Xerox, Rackspace, IBM, and Amazon use IaaS providers (Ahmad et al., 2022, p.p. 1903–1904).
