The problems caused by large websites

are mainly from three aspects

  1. Large concurrency

    1. The concept of concurrency: For a website, at a certain point in time (usually within 1 second), access The sum of users, the average is meaningless at all. Usually the highest point value. Generally, servers are configured at this highest point and then add 30% redundancy.

  2. Large traffic

    1. is mainly used for user visits, and each page has a lot of data that needs to be transferred.

  3. Storage itself is not a problem, but retrieval is a problem

  4. Adding of user attachments

  5. Insertion of data records

The above introduces the problems caused by large websites. It includes content on large websites, and I hope it will be helpful to friends who are interested in PHP tutorials.
