Why are Alibaba Cloud servers always so unstable and often crash and offline?

Occasionally, I will see webmasters complaining that Alibaba Cloud servers are unstable, often crashing and disconnecting, and then saying that Alibaba Cloud's various services are not reliable. Objectively speaking, Alibaba Cloud's market share in mainland China is still very high. It is recommended that everyone buy a regular Alibaba Cloud server. After a successful purchase, it is recommended that professional people do professional things and ask experts to help optimize the server and site, so that it can Stay away from server instability and crashes (except when attacked).

It’s just like computers with the same configuration, and the nature of work is similar, but some employees crash and freeze while using the computer, but some employees still use it smoothly and without problems for several years. In the same way, some webmasters always complain that the Alibaba Cloud server is unstable and will crash, but some webmasters have been using it for several years without necessarily crashing or restarting the server.

To be honest, I have been using Alibaba Cloud servers for so many years. Other servers or virtual hosts are purely for practice, so I still trust Alibaba Cloud servers. After all, after so many years of use, Alibaba Cloud servers have always been quite stable, except for occasional lags when attacked. Therefore, if the server often crashes and becomes unstable, it is recommended to check it yourself or ask a friend to help you check to see if the server configuration is not up to date, or it is a configuration problem or a program problem, and then solve the problem.

There are no solutions to the problems raised by some webmasters such as "Why are Alibaba Cloud servers always so unstable and often crash and offline?" However, based on years of experience, I will give you 4 suggestions that can reduce the risk of server crashes. Probability, as follows:

1. Purchase Alibaba Cloud servers on the Alibaba Cloud official website. Do not go to Alibaba or other third-party platforms to buy so-called "Alibaba Cloud servers", and do not buy burst performance servers in order to save so-called costs, unless you are very Know how to optimize servers and sites, otherwise it is recommended to buy a server with 100% CPU performance.

2. Purchase a server that matches the site traffic. For example, you have several sites on one server, and the traffic of each site is thousands or tens of thousands. In this case, if you still use a low-configuration server, unless the server is optimized to the extreme, it will probably not be able to handle it. living. If the site reaches this situation, you might as well invest a little more to upgrade the server to make it run more smoothly and the site to be more stable, so that the site will get better and better.

3. Many webmasters purchase Alibaba Cloud servers and then do their own work. For example, after installing the Pagoda panel, they build various blog websites. It is recommended that after successfully purchasing an Alibaba Cloud server, you can pay an expert to help optimize the server

4. After building a site, you must also perform certain optimizations. For example, if you build a WordPress site, but you have installed many foreign plug-ins and directly use foreign WordPress themes, then this site will be better than those in mainland China. Sites with themes and a few plugins will be much slower. Therefore, it is recommended not to install too many plug-ins on the WordPress site, and it is not recommended to directly use foreign themes (Mainland China servers) or pirated themes. DUX themes are good, have been stably updated for many years, and have many users
