This article mainly introduces the main service forms of cloud computing, which can be used for reference. I hope you can learn a lot after reading this article. Let's take a look at it.

The main service forms of cloud computing are: 1, software as a service; 2, platform as a service; 3, information as a service. Among them, information as a service refers to the manufacturer's cloud infrastructure composed of multiple servers as a measurement service to customers.

The main service forms of cloud computing are SaaS (Software as a Service), PaaS (platform as a Service) and IaaS (Information as a Service).

The SaaS service provider uniformly deploys the application software on its own server, and the user orders the application software service from the manufacturer through the Internet according to the demand. The service provider charges according to factors such as the quantity and time of the software ordered by the customer, and provides the software model to the customer through the browser. The advantage of this service model is that the service provider maintains and manages the software and provides hardware facilities for the software to run. Users can use the software anytime and anywhere as long as they have terminals that can access the Internet.

In this mode, customers no longer spend as much money on hardware, software and maintenance personnel as in the traditional mode, but only need to pay a certain amount of rental service fees, and can enjoy the corresponding hardware, software and maintenance services through the Internet. this is the most cost-effective operation mode of network application. Both Salesforce.com and Google Apps fall into this category.

PaaS is a kind of distributed platform service. Manufacturers provide development environment, server platform, hardware resources and other services to customers. Users customize and develop their own applications on the basis of their platform and deliver them to other customers through their servers and Internet. PaaS can provide enterprises or individuals with a middleware platform for research and development, and provide application development, database, application server, trial, hosting and application services. Google App Engine platform, 800-passenger 800APP is the representative product of PaaS.

IaaS provides customers with the manufacturer's "cloud" infrastructure of multiple servers as a metering service. It integrates memory, Ihammer O devices, storage and computing power into a virtual resource pool to provide services such as storage resources and virtualized servers for the entire industry. This is a managed hardware approach, where users pay to use the manufacturer's hardware facilities. The advantage of IaaS is that users only need low-cost hardware and rent corresponding computing power and storage capacity on demand, which greatly reduces the cost of hardware. Amazon Web services (AWS), BlueCloud of IBM, etc., all rent infrastructure as services.

Thank you for reading this article carefully. I hope the article "what are the main service forms of cloud computing" 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!
