system expansion capability. More than two servers to work together must involve load balancing problem, the current commonly used load balancing technology are: NAT load balancing, reverse proxy

The advantages of Network Load Balancing 1. Network Load Balancing allows you to propagate incoming requests to up to 32 servers, where you can use up to 32 servers to share external network request services. Network Load

machine. It can allocate HTTP processes to several IP hosts. Such systems use simple PING commands to ensure that process requests are not sent to an unsatisfactory server, and a variable is introduced for multiple servers to display the Failover rate. The second generation of Server Load balancer not only undertakes the task of checking whether the server is running, but also checks the server's performance status. That is to say, if a server is ove

With F5, A10, deep conviction and other traditional debt-balanced products, NetScaler is generally done based on the application of load balancing, and for the load balance of the link is relatively less than the actual scenario, their own side of the current use of the company developed Web server to do

backbone network from conventional third layer to comprehensive third-layer, fourth-layer switching function, its unique WAN integration capability and the access control based on layer fourth exchange have played a key role in secure and orderly network data transmission. In addition, Cabletron SmartSwitch router provides different levels of prioritization for specific business application data exchange based on the QoS features of layer fourth switching. 　　3 Implementing server

Preface:At present, many Web applications, or Web interfaces, will be at the entrance of the server, using a server container to listen to the port, and then make request forwarding, such as Nginx Apache. Server containers are critical to the entire Web service, including the ability to manage service processes, perform proxies, pre-process requests, and

(Network File System) sharing services. The typical topology of the Server Load balancer cluster is as follows: 3. Load Balancing Mode The Cluster load scheduling technology can be distributed based on IP addresses, ports, and content. The IP-based Server

Load balancing is composed of multiple servers in a symmetrical way of a server set, each server has the equivalent status, can be provided to the external service alone without the assistance of other servers. Through some load-sharing technology, the externally sent requests are evenly distributed to one of the servers in the symmetric structure, and the server

Overview Load Balancing is built on the existing network structure, it provides a cheap, effective, and transparent method to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability.Prerequisites You have installed Apache and can run it. The system used in this article is: centos6.2, Apache: Apac
