Detailed explanation of high concurrency solution of Java System

For a small website, such as a personal website, the simplest HTML static page can be used to achieve the beautification effect with some pictures. All pages are stored in one directory. The requirements for system architecture and performance of such a website are very simple. With the continuous enrichment of Internet business, the technology related to the website has developed over the years, It has been subdivided into very detailed aspects, especially for large websites, the technology used covers a wide range, from hardware to software, programming language and MySQL "target ="_ Blank "title =" MySQL knowledge base "> database, webserver, firewall and other fields have high requirements, which can no longer be compared with the original simple HTML static website.

Large websites, such as portals. In the face of a large number of user access and high concurrent requests, the basic solutions focus on the following links: using high-performance server, high-performance database, efficient programming language and high-performance web container. However, in addition to these aspects, it can not fundamentally solve the high load and high concurrency problems faced by large websites.

To some extent, the solutions provided above also mean greater investment, and such solutions have bottlenecks and do not have good scalability. Let me tell you some of my experience from the perspective of low cost, high performance and high scalability.
