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 interruption may occur. In the past, when so
The static and dynamic separation in this paper is mainly realized by Nginx+tomcat, in which the nginx handles the images, HTML, JS, CSS and so on, and Tomcat handles the dynamic requests such as JSP and servlet.

Analysis of 6 kinds of load balancing algorithms, Ngnix 5 kinds of algorithms.?Floating SnatchHundred 03-21 10:06ConcernContent GuideIts actual effect is getting closer to the average allocation of calls to each server on the backend, which is the result of polling. The idea of the source address hash is to obtain the client's IP address, through the hash function to calculate a value, with this value to th
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
Reprint http://hi.baidu.com/aking_roc/item/3f62cb0f57b49736a3332a9eLoad balancer devices are also often referred to as "four to seven layer switches", so what is the difference between the four and seven tiers?First, the technical principle of the difference.The so-called four-layer load balancing , that is, mainly through the message of the destination address and port, coupled with the
As developers of back-end applications, we often develop, debug, test and publish our applications to the production environment, and users have direct access to our applications. But for Internet applications, there is a low profile or thick or thin layer of load balancing software between your application and users, and they do not show the dew silently playing an important role, so much so that we often
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 scheduling algorithm, The request is sent to the back
. Apache can have a good static page processing capabilities, if paired with Tomcat can support both static and dynamic pages
2. Tomcat can assume low performance requirements for Web applications. Load Balancing
In order to improve the usability and performance of the whole system, load balancing is often used, while
It is best to divide the routing load balancing network segments. This will not disrupt the routing behavior at the network layer, because the host or router forwards each packet through the "Route" found in the route table, unless the load balancing of the route table is achieved, otherwise, only a unique route is sel
1. Overview
The interaction between the DHCP Client and the DHCP Server involves both broadcast packets and unicast packets (used during renewal, we know that the general Server Load balancer equipment implements Load Balancing for unicast packet data, so the pure DHCP Client-> DHCP Server architecture basically cannot achieve
The Spring Cloud Gateway integrates Zuul and fuses, so gateways are inherently load-balanced and fused. Therefore, the load balancing algorithm of Spring cloud is the load balancing algorithm of ribbon. In the Ribbon, load
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

Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source
are many things to do. The Nat mode is simple, that is, to change the IP address and port information to the IP address and port of the real balancing machines, so that the real service machines are hidden behind the Load balancer, the idea is the same as that of normal Nat.[Tunnel mode]: The tunnel mode is to repackage data into a new IP data packet, and then send the data to the virtual Nic by modifying
