What are the three levels of services provided by cloud computing?

Three levels: 1. Infrastructure as a Service (IaaS), which provides virtualized computing resources to individuals or organizations of cloud computing providers; 2. Platform as a Service (PaaS), which provides developers with global The Internet is a platform for building applications and services; 3. Software as a Service (SaaS), which provides on-demand software paid applications through the Internet.

The services provided by cloud computing can be divided into three types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service ((SaaS)) level.

Cloud computing is a type of distributed computing, which refers to decomposing huge data computing processing programs into countless small programs through the network "cloud", and then, These small programs are processed and analyzed through a system composed of multiple servers to obtain results and return them to the user. In the early days of cloud computing, simply put, it was simple distributed computing that solved task distribution and merged calculation results. Therefore, cloud computing Computing is also called grid computing. Through this technology, tens of thousands of data can be processed in a short time (a few seconds), thereby achieving powerful network services.

Types of cloud computing services

Generally, its service types are divided into three categories, namely Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). These 3 cloud computing services are sometimes called cloud computing stacks because they build stacks that sit on top of each other. Here is an overview of these three services:

1. Infrastructure as a Service (IaaS)

Infrastructure as a Service is one of the major service categories that provides virtualized computing resources, such as virtual machines, storage, networks, and operating systems, to individuals or organizations at cloud computing providers.

2 ,Platform as a Service (PaaS)

Platform as a Service is a service category that provides developers with a platform to build applications and services over the global Internet. PaaS provides on-demand services for developing, testing, and managing software applications Development environment.

3. Software as a Service (SaaS)

Software as a service is also a type of service, which provides on-demand software paid applications through the Internet, and is hosted and managed by a cloud computing provider software application and allows its users to connect to the application and access it through the global Internet.
