This article mainly introduces how many levels the services provided by cloud computing can be divided into, which has a certain reference value. Interested friends can refer to it. I hope you will learn a lot after reading this article. Let's take a look at it.

There are three levels: 1, Infrastructure as a Service (IaaS), providing virtualized computing resources to individuals or organizations of cloud computing providers; 2, platform as a Service (PaaS), providing developers with a platform for building applications and services over the global Internet; and 3, Software as a Service (SaaS), providing on-demand software-paid applications over the Internet.

The services provided by cloud computing can be divided into three levels: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).

Cloud computing (cloud computing) is a kind of distributed computing, which refers to the decomposition of huge data processing programs into countless Mini Program through the network "cloud", and then through the system composed of multiple servers to process and analyze these Mini Program results and return them to users. In the early days of cloud computing, to put it simply, it was simple distributed computing, solving task distribution, and merging computing results. Therefore, cloud computing is also called grid computing. Through this technology, tens of thousands of data can be processed in a very short time (a few seconds), thus achieving a powerful network service.

Types of cloud computing services

In general, 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 three cloud computing services are sometimes called cloud computing stacks because they build stacks and they are 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 main service categories that provide virtualized computing resources, such as virtual machines, storage, networks, and operating systems, to individuals or organizations of cloud computing providers.

2. Platform as a Service (PaaS)

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

3. Software as a Service (SaaS)

Software as a service is also a category of services that provide on-demand software-paid applications over the Internet, and cloud computing providers host and manage software applications, and allow their users to connect to applications and access them over the global Internet.

Thank you for reading this article carefully. I hope the article "how many levels of cloud computing services can be divided into" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
