What Are the Different Types of Dedicated Servers?

Server types are divided into four types: entry-level servers, workgroup-level servers, department-level servers, and enterprise-level servers according to the application level; they are divided into general-purpose servers and dedicated servers according to their purposes. It can also be divided by chassis structure, processor architecture, and so on.

Server type

Server type, divided by application level

Divided by application level:

By server processor architecture (ie

Divided by server by usage

According to the chassis structure of the server, the server can be divided into "desktop servers", "

The server is the most basic facility for website operation. If the server fails, it will not only affect the user's access to the website, reduce the user loyalty of the website, but also reduce the trust of the search engine to the website.

Therefore, before the website goes online, you should prepare a stable server for it. From the standpoint of search engine optimization, when choosing a server, we need to pay attention to the following points:

1.Country (region) where the server is located

When selecting a web server, at least both ordinary users and search engines should be considered.

(1) From the perspective of the user, when the user visits the website, their main requirement is that they can quickly open the web page or resource they want to browse;

(2) From the perspective of search engines, it hopes to provide users with the information that is closest to their region. (Many people have asked why the search keywords in the two places are not the same. ) To improve the user experience of search results. Therefore, search engines preferentially return websites that are in the same country as the user.

Based on the above two conditions, when choosing a server, we should choose the server closest to the location of the customer base. This will not only reduce the time required for users to download web pages or resources, but also When it comes to content-related information, the website can also get priority ranking.

2. Server stability

Unlike traditional stores, the website operates 24 hours a day. If the server system fails, users will not be able to access the relevant websites, and some potential customers will be missed. In addition, the stability of the server will also affect the performance of the website in search engines. If a website is unavailable for a long time or frequently makes mistakes, it will cause the search engine to clear pages that it cannot access during its multiple visits or updates, or even degrade the website as a whole. This is one reason why websites suddenly drop in ranking or even disappear in search results for certain keywords.

Therefore, when choosing a server, you should give priority to those who have a good reputation or purchase independent servers. Never choose a low-quality server for the price difference of several hundred yuan a year. This is not worth the money.

(1) Broadband

For server hosting, renting a standalone server or a shared server, the first thing we must consider when choosing a server is the available bandwidth of the server.

There are many independent servers. Hosters generally only provide 100M shared bandwidth, but it will not clearly indicate how many servers share this 100M bandwidth. So be sure to figure out what the minimum bandwidth for each server is before buying. For ordinary information websites, the minimum bandwidth can be around 5M to meet basic needs.

(2) Server resources

For shared-type servers, in addition to the bandwidth limitations of the server increaser, the server resources used by each user in the shared server are also limited, including software and hardware resources, such as CPU, memory, hard disk space, and bandwidth. Therefore, we must choose the appropriate server based on the number of website visits.

Similarly, when the resources on the server cannot meet the needs of the website, server access timeouts will also occur, which will affect the search engine friendliness of the website.

(3) Number of connections

If you purchase a virtual space, the space provider will generally limit the number of connections that can be accessed. This is the IIS limitation that everyone is familiar with.

In practical applications, we should choose the corresponding level of space according to the actual situation of the website. For example, if the peak number of concurrent online users of a website is more than 150, then when selecting a virtual space, the number of connections should be greater than 150, otherwise there will also be access timeouts, which affects the search engine friendliness of the website.

(4) Monthly traffic

Some virtual spaces do not limit the number of website connections, but will limit the monthly traffic of the website. For this type of space, we also need to choose according to the actual situation of the website, otherwise there will also be access timeouts and other phenomena, which will affect the search engine friendliness of the website.

Server functions

When optimizing the website, we may also have some special needs. Such as: URL rewriting, 404 pages, etc.

(1) Whether to support URL rewriting

In order to facilitate maintenance, many websites will use a database for management, which involves the problem of static web pages. There are two methods for static web page statics: the first is to generate a static page using a program; the second is to implement pseudo-static through URL rewriting.

If URL rewriting is to be performed, the web server must have the corresponding components or modules installed. Such as: the ISAPI_Rewrite component of the IIS server; Mod_rewrite of the Apache server.

(2) Data backup

Due to various reasons, data may be lost during the operation of the website. Therefore, whether the domestic server space we purchased supports regular data backup is also very important. If the web server has a backup function, then we can resume the operation of the website in the shortest time.

First, the price issue: is the most concerned by buyers. Of course, it is best to be able to buy cheap and good products, but you should not be too attached to the price, otherwise it will be easy to enter the trap of some businesses. After all, the value of the product is mostly proportional to the price. You must choose excellent quality to ensure the stability of the website. At the beginning of the construction of the station, when there is not much popularity, you can choose some low-end products with strong and reputable service providers. The products of large companies have incomparable advantages over small companies.

2. Whether it can be accessed normally: If the users of the corporate website will be directed to China, the question to be considered is whether the IP address on the company's virtual host can be accessed smoothly in China. If you ca nt buy the access, it s more troublesome to refund it. For example, some foreign host servers are very good host companies in foreign countries, but their IP access is not complete in China. Do not buy such hosts.

Third, the stability of the virtual server: including the stability of both the server and the company. Pay more attention to the license number of the website, ISP or IDC license number: ISP and IDC licenses can not be applied by ordinary companies, only those strong and reputable service providers can be obtained after strict review. In addition, these factors, such as bandwidth resources, power systems, air conditioning systems, security systems, and whether they are self-built computer rooms, must be carefully considered.

Fourth, the host traffic parameters and after-sales service problems: Generally speaking, they provide sufficient traffic. Many businesses carry promotions with unlimited traffic, unlimited CPU, and IIS banner. However, basic operators such as telecommunications and China Netcom still restrict traffic. How can service providers guarantee this commitment? So a lot of complaints about traffic can be found online. Due to the lack of professional technical staff during the construction of the station, they are expected to be repaired in time after a failure. 7 * 24-hour technical support services have become very important. If a virtual server without such a server is provided, it can be ignored. ^[2]
