the performance bottleneck of the firewall as a site, multiple firewalls are used to achieve load balancing, as shown in the following figure (for details, we will discuss it later ): Next, let's take a look at some Server Load balancer products. Load Balancing products can basically be divided into three

Haproxy configuration for Server Load balancer and haproxy configuration for Server Load balancerCommon Open-Source Software load balancers include Nginx, LVS, and Haproxy. Comparison of three major software

Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup; Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

Nginx Server Load balancer transmits the parameter method to the backend (the backend is also an nginx server), and nginx Server Load balancer A website uses nginx for load balancing and multiple nginx servers at the backend. Encountered a problem, when it is used as SSL sup

, and there are few server cluster software implemented using this method. In some cases, you can use CGI (including FastCGI or mod_perl extension to improve performance) to simulate this method to share the load, while the Web server still maintains a concise and efficient feature, in this case, the user's CGI program is responsible for tasks that avoid Location loops. 　 　　 2.

support functions related to server load balancer, such as the redirection capability in HTTP, but they depend on specific protocols, so the scope of use is limited. Based on the existing server load balancer technology, we chose the server load

, redundancy is also necessary. This involves the design of efficient dB, which will not be repeated here. 2.1.2 why data splitting What is data splitting? A brief description and explanation are provided. Readers may wonder why data splitting is required? A mature and stable database like Oracle is enough to support the storage and query of massive data? Why do we still need data slicing? Indeed, Oracle da

is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering , which I call group, that is, each node of the library we introduce multiple machines, each machine holds the same data, in general, many of these machines load, when there is a downtime situation, The load balancer allocates the

group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer distributes the load to the machine that is down when there is an outage. This solves the problem of fault tolerance.As shown, t

To use this class, make sure that the catalina-cluster.jar (located in the % tomcat_home %/Server/library directory) And the commons-logging-api.jar (located in the % tomcat_home %/bin directory) file is specified in classpath.

: Each request from the network is distributed to each internal server in turn, starting from 1 to n and then restarting. Example: This balancing algorithm is suitable for all servers in the server group with the same hardware and software configurations and Relatively Balanced average service requests; -Least connection algorithm (least connection ): Note: Each time the client requests the service to stay on the server, there may be a big diff

load balancing policy1. Server Load balancer based on specific server software many network protocols support the "redirection" function. For example, HTTP supports location commands, the browser that receives this command will automatically redirect to another URL specified by location. Since sending location command
