sticky load balancing

Load Balancing cluster is currently the most used cluster type, through the primary node load scheduler (Director), using a specific shunt algorithm, the access requests from the client to a number of server nodes to work together to alleviate the overall system load pressure, response to more requests; cluster

There are several ways to load balance:one, based on the client way:Each client program has a certain knowledge of the server cluster, which in turn sends requests to different servers in a load-balanced manner. This approach is primitive, and now some older systems are still using this approach, and the client simply uses polling to achieve load

Azure Load Balancing Load Balancing Overview: Microsoft Azure provides load balancing services for virtual machines (IAAS) and cloud services (PAAs) hosted in it. Server Load balancer s

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 load balance. The focus of today's discussion is to make more meaningful

In Linux, dual-Nic binding technology achieves load balancing and failure protection (in Centos5 and Centos6). maintaining high server availability is an important factor in the enterprise IT environment. The most important thing is the high availability of server network connections. NIC binding helps ensure high availability and provide other advantages to improve network performance. We will introduce th

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load

The load master can provide many kinds of load balancing methods, that is, we often call the scheduling method or algorithm:Round robin (Round Robin)This method loops the received requests to each machine in the server cluster, which is the active server. If this is the case, all the servers that are tagged into the virtual service should have similar resource ca

LVS Load BalancingRecently in the study server load Balancing, read some information on the Internet, found that the main software load Balancing scheme has nginx (load balancing for HT

Load BalancingLet's start with a quick look at what is load balancing, which is interpreted literally to explain the average load sharing of n servers, not because a server is under-loaded and idle on a single server. Then the premise of load

Jkmount/*.do Controller If you want to triage all requests just write Jkmount/controller 4. Create a new workers.properties file in the same directory as http.conf (you may want to remove the note with # Not at the beginning of the line) Worker.list = controller,tomcat1,tomcat2 #server list #====== ==tomcat1======== worker.tomcat1.port=8009 #ajp13 port number, server.xml configuration under Tomcat, default 8009 worker.tomcat1.host=localhost # Tomcat host address, if not native, please fil

Document directory IGMP multicast (IGMP Multicast) Refer: http://blog.csdn.net/ghj1976/archive/2009/03/17/3997840.aspx Recently, we are studying how to achieve Load Balancing (NLB) for csdn Forum Web servers ). Below is my documents: How NLB works Features of the NLB algorithm: In the NLB cluster, each server has its own static IP address, and all servers in the NLB Cluster also have a common IP a

The pros and cons of load balancing strategies and their ease of implementation have two key factors:(1) Load Balancing algorithm(2) The detection mode and ability of network system condition1. round robin (Round Robin): Every request from the network is assigned to an internal server in turn, starting from 1 to N an

Server load balancer (SLB) has a high score. four web servers use server load balancer. four db servers also use server load balancer. I want to write something to check whether the eight servers connected to the two server load balancer can be connected, sometimes one or two servers are down but I don't know, so I wan

Understanding of Nginx Load BalancingNginx is a lightweight, high-performance webserver, he can mainly do the following two things:As an HTTP server (as with Apache)Load balancing as a reverse proxy serverNow Nginx everywhere can be seen, often see the page after the outage will show Nginx words, which also shows that nginx because of high performance, use config

First, download NginxHttp://nginx.org/download/nginx-1.2.5.zip Extract to C:\nginx directory Second, on the two servers to build a website: s1:192.168.16.35:8054 s2:192.168.16.16:8089 Second, find the directory C:\nginx\conf\nginx.conf Open nginx.conf The configuration is as follows: Copy Code code as follows: #使用的用户和组, not specified under window #user nobody; #指定工作衍生进程数 (generally equal to twice times the total number of CPUs or sums, such as two quad-core CPUs, the sum of whi

In the past, running a large Web application meant running a large Web server. Because your application attracts a large number of users, you will have to add more memory and processor to your server. today, the ' big server ' model is over, replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible way to minimize the cost of hardware. ' More small

Nginx can serve as an efficient HTTP Load balancer to
