Web cluster selection and implementation of load Balancing scheme for service The Web application server cluster system is a cluster system composed of a group of servers running the same Web application at the same time, which looks like a server to the outside world. In order to balance the

LVS Load Balancing clusterTypes of clusters1, load Balancing cluster: To improve the corresponding ability of the application system, as far as possible to deal with more corresponding requests, less latency as the target, get the overall performance of high load concurrency

/weight of each back end, and select the backend with the lowest value. If there are multiple back-end conns/weight values with the same minimum, then the weighted polling algorithm is used for them.What is load balancingWe know that the performance of a single server is capped, when the traffic is very large, you need to use multiple servers to provide services together, this is called the cluster.A

Article title: Dual-Nic binding technology in Linux for load balancing. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Maintaining the high availability of servers is an important factor in the enterprise IT environment. The most important thing is the high availability

Source: Network Collection In general, load balancing is the client's request to the backend of the various real servers to achieve load balancing purposes. There is another way is to use two servers, one as the primary server (master), the other as a hot Standby, the requ

number of users that can be supported by the cluster system and the time required to process a request. 　　 Among the many existing methods of balancing server load, the following two methods are widely studied and used: 　　 DNS Load Balancing Method Rr-dns (round-robin D

, the fastest response algorithm does not work very well, because the ICMP packets in the LAN are basically in the 10ms response, not the difference between the nodes; assuming a balance on the WAN, The response time is still of practical significance for the user to select the server at the nearest, and the more dispersed the cluster topology, the more effective the method will be.Such a method is the primary method of advanced

Nginx reverse proxy for load Balancing configuration diagram[Introduction] Load Balancing configuration is a very large machine needs to consider some of the problems, but also a data security approach, let me introduce the reverse proxy load Balancer configuration diagram i

Load Balancing cluster (LB)How load Balancing clusters workWhen a user sends a request, the request is not immediately sent to the backend's real server (realservers), but is sent first to the Scheduler or Distributor (Director), and then the director, based on some scheduli

1. Load Sharing-solutions for large service nodesA large amount of access traffic and users are the goal of information service providers. However, a large amount of access will impose a heavy burden on servers. As the number of users of excellent Internet application services increases, the server becomes overloaded. If a large number of user service requests cannot be processed in a timely manner, service
