Tasting the three major forms of the actual operation of the data center

In recent years, data center technology has been developed rapidly, the form of data center has gradually diversified, the traditional closed data center http://www.aliyun.com/zixun/aggregation/9942.html "> Technology architecture behind, Low resource allocation capacity, uncoordinated management and development, and the average utilization of resources are only 20%~30%, these data centers are difficult to keep pace with technological progress. Currently, there are more than 640,000 data centers in China, but the utilization rate is low. As people attach importance to the construction of Green data center, data center will become more and more form, in order to save energy and provide data center operation efficiency.

At present, the data center has three kinds of existence way: First, the enterprise builds the data center, the second is rents the operator data center, three is rents the data center to provide the service. Since the data center is a traditional form of data center, leasing operators data center is becoming popular with the development of Internet enterprises, with the advent of Aliyun, Century interconnected data center, telecommunication cloud and so on, the form of directly renting data center service is beginning to appear.

Enterprise self-built data center

Many large enterprises have their own data centers and then interconnect multiple internal data centers by leasing operators ' WAN lines. For example: Military network, public security Network, Ping An project, banking industry, oil industry, etc., these private network use are proprietary data centers, by the major government departments, enterprises led by themselves. This kind of data center invests big, the construction cost is high, has the closeness, specially provides the service for the individual enterprise or the department. As the construction of data centers to apply for industrial building land, to be the power supply departments, construction departments agree, procedures are very cumbersome. And after completion to put into use, often takes several years, the construction cycle is long, this kind of data center is especially suitable for the "high handsome" no shortage of money industry, in the era of fierce competition, its increasingly lack of advantages. In the United States, has begun to force some data center shutdown, strict control of the approval of new data centers, a large number of data centers consumes a lot of electricity in the United States, a heavy burden on the country. China is now in the rapid construction of data center development stage, the problem of energy consumption has begun to appear, with people's attention to energy conservation, environmental protection, the way to build data center will be more difficult. But this kind of self-built data center, because is completely self-built, the use is very flexible, may change according to own demand arbitrarily, the flexibility is high, especially this kind of self-built data center security is highest, the information leaks, the likelihood of being attacked is greatly reduced.

Rental operator Data Center

The internet has been developing rapidly these years, now people's life has been completely inseparable from the Internet, the expansion of Internet enterprises is also fast, since the periodicity of the data center is too long, obviously difficult to meet. Therefore, the direct leasing operator's data center room is the main form of its data center. Whether it is Baidu, Qihoo 360, or Sohu, Sina and so on most of the data centers are leased operators. Operators provide venues, cabinet, network bandwidth and power supply, the Internet enterprise directly put the equipment into the operator network, so generally, only one week can build a data center and put into use, very fast, this way in the Internet enterprise is very common, so the Internet enterprises only need to pay attention to their own application equipment ( Network equipment and server is mainly the operation of the state can be, do not care about the computer room environment, air-conditioning, power supply and a series of problems. Although the operators to pay a large amount of rent, but still can save the Internet enterprises a lot of manpower and material resources. Internet enterprises and can according to their own business reality, at all levels of operators in the provinces and cities to rent data center room, rapid deployment of business. Of course, in the operator's family of three acres of mixed, there are still some restrictions, such as the maintenance of computer room environment, equipment access management are limited by operators. The lease period, the new room area must communicate with the operator, need the operator's consent to implement. These internet companies want to develop a good first and these operators to do well relations.

Tencent, Taobao, these big manufacturers have begun to build some of their own data centers, the construction of these data centers not only need a lot of money to support, but also need the support of government departments, not want to build it can be built.

Renting services provided by the data center

This is a new type of data center that has emerged in the last two years, provided by large data centers and is the Gospel of small and medium-sized enterprises. Small and medium-sized enterprises are limited in funding and background, it is difficult to build and hire operators to maintain their own. By leasing the services of a large data center directly, you can deploy your business. For example, according to their business needs, to the Aliyun leased 100GT hard disk and 200G of memory, 10G of bandwidth, for small and medium-sized enterprises, to meet these performance physical hardware is completely invisible. So enterprise users can focus entirely on their own application business, do not care about the bottom of the data center implementation, but also for the enterprise to save manpower. Of course, such a form makes the enterprise's core business stability and rental data center operating stability, sometimes failure, because the enterprise itself can not see the data center to achieve the bottom, only Gan and other business recovery. Sometimes there will be shifting, and because the hirer is in a weak technical position, it is often difficult to compensate for the loss caused by the failure. This way there is a fatal flea power, that is, security. In addition to the upper application, the data center is not under the control of the underlying implementation, there is no means of attack, so security depends entirely on the tenant's data center. Therefore, when you choose to rent a data center service, you need to fully consider the security of its data center. There are still relatively few data center application services, only a few, the competition is not sufficient, this gives small and medium-sized enterprises to choose less. With the intensification of competition, the entry of international giants, such as Amazon, Microsoft are ready to build data centers in China, the external provision of data center services, then this kind of unequal status will be eased.

Whether it is built or rented, there are pros and cons, not to say which way is better. The leasing of data center services represents the future direction of the data center and the potential for development, while the traditional self-built data centers, though controversial, will remain in place for a long time, with large corporations and government departments still willing to build fully self-contained data centers. In the future for quite a long time, these three ways must be long-term.
