This means that it can be shared across multiple operating units, such as Web servers, FTP servers, enterprise critic
F5 is one of our most popular Server Load balancer products, so here we will introduce its configuration on the actual business platform. Through this case, I hope you will have a clear understanding of the specific use and configuration of this product. For more information, please refer to the following section.I.

Today, the 'large Server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs.
The 'more servers' mode has more advantages than the 'large Server' mode in the past. It is reflected in two aspects:
1. If the server goes down, the Server Load balan

Use layer-4 switching technology to achieve server load balancingThe following design comes from the practical application of the network center of a Network Education College in a university. The layer-4 switch of Alteon provides Server

Where Master is responsible for the load of the write operation, which means that everything written is done on master, while the read operation is distributed on slave. This can greatly improve the efficiency of reading.

2.Server Load balancer application scenarios:
After receiving a large number of HTTP requests, the Nginx front-end tries its best to evenly distribute requests to the game servers on each server through certain policies to avoid the pr
collected by Listener. During database operation, the pmon Process collects system load information and regularly updates it to Listener. If you have configured the Remote_listener parameter, the pmon process not only registers the load information to the local Listener, but also registers the Listener of other instances. With the pmon automatic registration mechanism, the Listener of each node in the clus

executes NAT on the server side, so filtering the Client IP address does not apply to traces on the server side.
This problem can be solved by entering Layer 3. You can filter according to the serial number in the TCP header. However, be careful. Wireshark displays the relative serial number by default. In the end, you will encounter hundreds of packets with a serial number of 1. The key is to disable the relative serial number in the TCP Parameter option. As long as you deselect this option, t

Use Apache as the httpserver and connect multiple Tomcat application instances, and load balancing. 2. Set the Session Timeout time for the system, including Apache and tomcat 3.

In addition, DNS, as a request scheduler, cannot take the load capacity of each server, the current Load Status of the server, and other factors into account when the request is balanced, real Load Balancing may not be implem
