When the number of users reaches a certain level for an Internet system with a large user access volume, the system will always have bottlenecks or processing limits, which means it is difficult to respond quickly and the processing efficiency is gradually low. A more intuitive solution to cope with the increasing number of users is to adopt a distributed system

Many times we need to see whether the current Linux system is a 32-bit or 64-bit system architecture type, and I will recommend 5 common commands in this article. Whether you're using a desktop version or a Linux environment with a text-only interface, the following commands can be used for almost all Linux distributions, such as RHEL, CentOS, Fedora,
utilization multi-CPUThis architecture, which divides multiple processes, typically has two strategies: one that is broken down by function, such as a process that is responsible for network processing, a process that is responsible for database processing, and a process that calculates a business logic. Another strategy is that each process is the same function, and it only shares different computational tasks. Using the first strategy of the
The architecture of web system is divided into three modes: b/S, c/s, peer.b/S: browser/server, browser/server mode.b/S Architecture features: standard protocol, flexible deployment, core operations on the server side, publishing applications only need to publish the server, with the increase of server computing power and the application of cloud computing, b/s
