数据中心的重点特点(数据中心需要了解什么)

The average, median, and mode reflect the location of the data center.

1. Average value. The average is an important indicator to measure the location of the data center. It reflects the inevitability of the data to a certain extent, including arithmetic mean, weighted arithmetic mean, harmonic mean, geometric mean, etc.

2. Median. The calculation method is to arrange all the data in order from small to large, and the data value in the center is the median (or the average of the two numbers in the center).

3. Mode. The mode refers to the data value that occurs most frequently in the data.

If the difference between each data is small, the average value will be better representative; if the difference between the data is large, especially if there are individual extreme values, use the average The median or mode is better representative.

What reflects the degree of data dispersion?

Reflecting the degree of data dispersion are variance, standard deviation and range. The variance is the average of the squared deviations of each value in the data group from its mean; the standard deviation is the square root of the sum of the squares of the differences between each data and the mean. The larger the number, the greater the degree of dispersion, and vice versa; the extreme Difference is the difference between the maximum and minimum numbers in a set of data. The greater the range, the greater the degree of dispersion.

The degree of data dispersion is another important feature of data distribution. It reflects the degree to which the value of each variable is far away from its central value, so it is also called the dispersion trend. Each measure of central tendency is a summary measure of the general level of the data. The degree to which it represents a set of data depends on the dispersion level of the set of data.

The new generation data center is nothing but garbage. This is the biggest feature

What are the main functions of Internet data centers? Let’s take a look at the editor’s sharing.
Internet data center functions: Enterprises can engage in activities such as machine space rental, rack rental, server hosting, host hosting, cabinet rack rental, network hard drive, storage space, cloud computing, cloud host, cloud platform, virtual host, server Leasing and other IDC businesses.

Expand your knowledge:
1. Relevant laws and regulations:
1. "Telecommunications Business Classification Catalog"
2. "Telecommunications Business License Management Measures"
3. "Telecommunications Business License Management Measures" Regulations
In addition, Internet data center IDC refers to providing placement, agent maintenance, system configuration and management services for users' servers and other Internet or other network-related equipment in the form of outsourcing leasing, as well as providing server equipment leasing and storage space leasing, proxy leasing of communication lines and egress bandwidth and other application proxy services. It is a B11 value-added telecommunications business classified by the "Telecommunications Business Classification Catalog". In addition, according to the "Telecommunications Regulations", a licensing system is implemented for telecommunications business classification, so enterprises engaged in Internet data center business are required to apply for an IDC license, which is called Internet Data Center Business License.

2. Characteristics of Internet Data Center
An excellent IDC should have the following characteristics.
1. Have the infrastructure to meet the needs of website system hosting outsourcing services. This facility includes stable and reliable broadband Internet access and a safe and reliable carrier-grade computer room environment.
2. Be able to provide high-quality value-added services, including system maintenance (such as system configuration, software installation, data backup, troubleshooting, etc.); managed services (such as bandwidth management, traffic analysis, intrusion detection, system vulnerability diagnosis, etc.) , data backup, load balancing, Cache service, etc.); support services (such as technical support hotline, etc.); integrated services (such as providing comprehensive integrated services of data center, integrated communications and IT professional services, etc.), etc.
3. It has the ability to provide high-speed network interconnection, allowing users from any network to access other operating networks at high speed. At the same time, through the provision of high-quality services, the regional restrictions on IDC users are basically reduced (for example, websites located in Shanghai can also host cross-regional hosting services at IDC in Beijing).
4. Allow users to greatly reduce their own operating costs through IDC's services.
5. Sign a complete service level agreement (SLA) with users.
