A brief analysis of several common forms of cloud computing

Perhaps a lot of people are not clear about some of the big forms of cloud computing, as the following article describes in detail, the InfoWorld Web site and dozens of of companies, analysts and it users discussed several major forms of cloud computing:

1.SAAS (software as service)

This kind of cloud computing service delivers programs to thousands of users through browsers. In the eyes of the user, such a form can save a portion of the cost of server and software authorization, and from a vendor's point of view, it only takes a single program to maintain, and it can drastically reduce costs. Salesforce.com is by far the most famous company of this kind of service. SaaS is used more in human resource management procedures and ERP. Google apps and Zoho Office are similar services.

2. Practical calculation (Utility Computing)

The idea was very early, but it was only recently that it was new in Amazon.com, Sun, IBM and other companies offering storage services and virtual servers. This cloud computing is the creation of a virtual datacenter for the IT industry that enables it to centralize memory, I/O devices, storage, and computing power as a virtual resource pool services for the entire network.

3. Network Services

Closely related to SaaS, network service providers are able to provide APIs that allow developers to develop more internet-based applications rather than providing stand-alone programs.

4. Platform as Service

Another kind of SaaS, this form of cloud computing provides the development environment as a service. You can use the middleman's device to develop your own program and upload it to users via the Internet and its servers.

5.MSP (Management service provider)

One of the oldest applications of cloud computing. This application is more for the IT industry rather than end users, often used for mail virus scanning, program monitoring and so on.

6. Business Service Platform

A mixed application of SaaS and MSP, a cloud that provides a platform for interaction between users and providers. For example, the user's personal expense management system can manage their expenses according to the user's setup and coordinate the various services they order.

7. Internet Integration

Integrate companies that provide similar services on the Internet so that users can compare and choose their own service providers more easily. The above describes several major forms of cloud computing.
