The purpose of building load balancing and service discovery ServicesAs the business of the website continues to improve, the performance of individual servers becomes increasingly difficult to meet the customer's business needs, so in many cases, multiple server instances and load balancers are needed to meet business needs.Nginx What is NginxNginx is a high-per
absrtact : For a large web site, load Balancing is the eternal topic. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 Big-ip, Citrix netscaler, Radware, etc., although it can solve the problem, but its high price is often prohibitive, So
three types of LVS load Balancing modesIn the Scheduler implementation technology, IP load Balancing technology is the most efficient, IP virtual Server Software (IPVS) is implemented in the Linux kernel?LVS Load Balancing Mode---
forwarding or the like, which is not a good user experience.If IIS is used for configuration, it is easy, but the JSP series do not fully comply with their own practices. You can also configure a single IP address with multiple domain names in Apache or Tomcat clusters in your own mode.
Requirements:
1. Static pages are responded by Apache, and dynamic JSP pages are processed by Tomcat.
2. There is only one server, but several JSP applications are re

The design of the balancing algorithm directly determines the performance of the cluster in load balancing. Poor design of the algorithm will lead to load imbalance in the cluster. The main task of the general
To improve server performance and workload, enterprises usually use DNS servers, network address translation, and other technologies to achieve multi-server load balancing, many of them use several servers to achieve Load Balancing for server access.
Currently, the so-called "Server

Applications can deliver messages over network shared memory for distributed computers.is a group of connected computers, from the outside it is a system, each node can be a different operating system or computer composed of different hardware. A cluster that provides Web services is a large Web server to the outside world. Howev

A brief introduction of LVSLVS is the short name of Linux virtual server, the Linux VM, a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now that LVS is already part of the Linux standard kernel, Before the Linux2.4 kernel, the use of LVS must be recompiled to support the LVS function module

Server cluster with a balanced policy Nowadays, servers must be able to provide a large number of concurrent access services, and their processing and I/O capabilities have become bottlenecks in service provision. If the customer's increase causes the communication volume to exceed the capacity of the server, the result will inevitably be: downtime. Obviously, the limited performance of a single server cannot solve this problem. The processing capacity of a common server can only reach tens of
