Comparison of IDC exclusive virtual host and shared virtual host for micro subnet data storage? Virtual hosts can be divided into exclusive virtual hosts and shared virtual hosts. Under what circumstances should users choose exclusive and share? Now let's follow our company to see their respective advantages.
Introduction to exclusive virtual host: Compared with shared virtual host, the biggest difference is the exclusive use of resources. It has a full server and independent resources, including central processing unit, memory, bandwidth, hard disk and IP, with unlimited traffic. Exclusive virtual host pre installs website application environment and database environment. It has the advantages of virtual host and server, and also provides a visual control panel environment, which is easy to operate. The exclusive virtual host runs fast and has strong security performance, which can avoid being implicated by other websites. It supports general parsing and can directly access the website via IP;
Introduction to shared virtual host: shared virtual host refers to that multiple users share the same server resources, including central processor, memory, bandwidth, hard disk and IP. At present, most virtual hosts in the market are shared virtual hosts. The advantages of shared hosts are also obvious: lower price, higher bandwidth, and more affordable; The disadvantages are also obvious. Because resources are shared (running memory, CPU, bandwidth, etc.), When other users of the server occupy more resources, their own host resources will be reduced. However, in general, operators will ask for suspension or upgrade when they find customers who consume resources. If other websites under the same IP address are attacked, all websites under the entire server [advanced defense, server] will be involved and cannot be opened. When the same IP website is penalized by the search engine for over optimizing or spreading spam information, it may be jointly penalized with all websites under the IP, and there will be penalties such as column reduction or right reduction, which will affect the optimization.
To sum up, we summarized the characteristics of shared virtual host and exclusive virtual host: exclusive version of virtual host: exclusive server resources, huge space, unlimited traffic and higher configuration of [video speed phone], which is the first choice for enterprises to build websites. Shared version virtual host: resource sharing, large space, fixed flow, economical and practical, meet the requirements of base station construction. I believe that after reading this comparison, you already know whether to share or enjoy it alone.
Comparison of IDC exclusive virtual host and shared virtual host for micro subnet data storage? The Hong Kong server was attacked by CC. How to deal with it? When we use Hong Kong hosts to build websites, we often encounter some malicious harassment or various attacks. Among these attacks, traffic CC attacks are common. CC attack is a legitimate request made to the host by simulating normal users to visit our website. So if the server is using a Hong Kong server? What should I do if I am attacked by CC
1. Install firewall in Hong Kong server for defense. In case of attack, we can defend by installing the server security dog and website security dog on the server. After installation, we can defend by opening the network firewall module of the server security dog and setting the website CC attack module. In case of low attack power, it can directly default to the lowest level of CC firewall. If the amount of attacks is large and the website opens slowly or cannot be opened directly, you can set it to Advanced, so that you can defend against CC.
2. Accelerate defense nodes by adding CDNs. We can use the popular CDN in recent years to accelerate external interception CC attacks. Whether it is normal users or abnormal attack traffic, when accessing the host, the normal host IP is invisible, and visitors usually visit the node rather than the host directly. Similarly, when attacking traffic, the traffic will directly hit the node rather than the host. In this way, [Chess Server] can play a role in protecting the host.
