Seven major forms of cloud computing services

Some say cloud computing is best for small and medium-sized enterprises, which makes the cost of small and medium-sized enterprises greatly reduced. If "cloud" brings a piece of cake to the IT department of a large enterprise, it can be regarded as a whole cake for small and medium-sized enterprises. It's a small company that has an old problem, a shortage of human resources, tight it budgets, and a nightmare of the millions of-dollar it device. Now, "cloud" for them to send a large enterprise-class technology, and upfront cost is very low, a relaxed.

The importance of this emerging trend is unquestionable, but it is only the beginning of a series of changes. Cloud computing not only the size of the enterprise caused by the gap between the pros and cons, and very likely to make the pros and cons of the potential of the main. Simply put, the most powerful and innovative technology in the world today is no longer unique to large enterprises. The cloud allows every ordinary person to reach the top it technology at a very low cost.

"Cloud" era

At the moment, PCs are still the core tool in our day-to-day life-we use PCs to process documents, store data, and share information with others via email or u disk. If the PC hard drive is broken, we will be stranded because of data loss.

In the "Cloud computing" era, the cloud will do the work of storing and computing for us. "Cloud" is the computer group, each group includes hundreds of thousands of units, and even millions of computers. The benefit of the cloud is that the computer can be updated at any time to ensure that the cloud is immortal. Google has several such "clouds", and other IT giants, such as Microsoft, Yahoo and Amazon, have or are building such "clouds".

At that time, we only need a computer to be able to access the Internet, do not need to care about the storage or calculation of which "cloud", but once necessary, we can use any equipment, such as computers, mobile phones, to quickly calculate and find this information. We don't have to worry about losing data any more.

Several major forms of cloud computing

1.SAAS (software as a service)

This type of cloud computing passes the program to thousands of users through the browser. This, in the eyes of the user, eliminates the expense of server and software authorization, and from a vendor standpoint, it is sufficient to maintain a single program, which can reduce costs. Salesforce.com is by far the most famous company for such services. SaaS is more commonly used in human resource management procedures and ERP. Google apps and Zoho office are similar services

2. Utility calculation (Utility Computing)

The idea was very early, but it was only recently that the Amazon.com, Sun, IBM, and other companies that provided storage services and virtual servers were reborn. 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 Service

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 (Administrative 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 Services Platform

SAAS a hybrid application of and MSP, which 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.
