- Mysql large website technical architecture core case analysis
- 7. On-demand: Extensible architecture of the website Extensibility: refers to the ability to continuously expand or improve system functions with minimal impact on the existing system. It is the opening and closing principle at the system architecture design level. The architecture design takes into account future functional expansion. When new functions are added to the system, there is no need to modify the structure and code of the existing system. Scalability: refers to the system's ability to enhance (reduce) its own computing and processing capabilities by increasing (decreasing) the scale of its own resources. A. Building a scalable website architecture 1. The greatest value of a software architect does not lie in how many advanced technologies he has mastered, but in the ability to divide a large system into N low-coupling sub-modules.

- There are several types of load balancing in linux
- Linux has 4 types of load balancing: 1. Layer 2 load balancing (mac), which uses a virtual mac address. External requests for virtual MAC addresses are received by the load balancer and the actual MAC address response is allocated to the backend; 2. Layer 3 load balancing (ip), using the virtual IP address method, external requests for virtual IP addresses, load balancing allocates the actual IP address response of the backend after receiving it; 3. Four-layer load balancing (tcp), starting from the fourth layer "transport layer" , use "ip+port" to receive requests; 4. Seven-layer load balancing (http).

- what is mysql router
- MySQL Router is a lightweight middleware officially provided by MySQL and is part of the InnoDB Cluster. It can provide transparent routing between applications and back-end MySQL servers; it is mainly used to solve the high availability and load of the MySQL master-slave database cluster. Issues such as balance and easy expansion. MySQL Router provides a virtual IP for the database cluster as a single connection point for the application. Through this single connection point, it can realize load balancing, read-write separation, failover and other database high-availability solutions.
