Today, I will talk to you about how to choose the server configuration according to the industry. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can gain something according to this article.

Generally speaking, large websites are developed from small websites, the initial stage of the site architecture is relatively simple, with the complexity of business and the surge in the number of users, began to do a lot of architectural improvements. When it was a small site, there were not many visitors, generally speaking, only one server was needed, when all the resources such as applications, databases, files, and so on were on one server.

However, with the development of website business and the increase of the number of users, a server can no longer meet the demand. A large number of user access leads to slower and slower access speed, and the increasing data will also lead to insufficient storage space. At this time, it is necessary to separate the application from the data. after the separation of the application and data, the whole website uses three servers, namely, the application server, the file server and the database server. These three servers are increasingly demanding hardware resources, and they need more powerful CPU, faster disks, and more memory to support these servers.

As the number of users continues to increase, the website will once again face challenges: too much pressure on the database leads to a decline in the efficiency of the whole site, and the user experience will be affected. For a website, most of its business visits are focused on 20% of the data. In the case of Weibo, for example, the Weibo with the most requests from Weibo is definitely those with big V fans, while few people pay attention to those small home pages. We can make use of this feature to cache this small part of the data in memory in advance instead of going to the database to read it every time, so as to reduce the access pressure on the database and improve the access speed of the whole website. The cache used by the website is generally divided into caching to the application server or caching to a special distributed cache server. Cached access to the application server is much faster, but it is often not applicable due to its own memory limitations. Remote distributed caching uses a cluster dedicated to caching services, which can be easily dynamically expanded when there is not enough memory.

After using the application server cluster to improve the concurrent processing ability of the website and using the cache, the pressure of data access has been alleviated, but the request connection that a single application server can handle is limited, during the peak period of website access, the application server has become the efficiency bottleneck of the whole website. When a server's processing capacity and storage space are insufficient, do not try to replace a more powerful server. For large websites, no matter how powerful the server is, it cannot meet the growing business needs of the site. In this case, it is more appropriate to add a server to share the access and storage pressure of the original server. As for the website architecture, as long as we can improve the load pressure by adding a server, we can continuously increase the server to improve the system performance in the same way, so as to achieve the scalability of the system. Application server cluster is a relatively simple and mature one in the design of website scalable architecture.

After reading the above, do you have any further understanding of how to choose the server configuration according to the industry? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
