simple load balancer

nginx/haproxy+keepalived as the load balancer, and the backend uses the MySQL database as a master and read-write separation, using the lvs+keepalived architecture. Of course, according to the specific needs of the project plan.The following is the respective characteristics and applicable occasions.NginxThe advantages of Nginx are: Work on the 7 layer of the network, can be targeted at the HTTP applic

Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often prohibitive, So

In network applications, "Server Load balancer" is no longer a new topic. From hardware to software, there are also many ways to achieve Server Load balancer. The server Load balancer discussed here does not refer to Server

As a Linux/Unix system engineer, I have been involved in external projects over the past few years. I have worked on the architectures of many small and medium-sized websites. F5, LVS, and nginx have many contacts, I want to explain to you what Server Load balancer is and what is a Linux cluster in a simple and easy-to-understand tone, to help you get out of this

large, which I have deep experience; 3, Nginx installation and configuration is relatively simple, easy to test, It basically can print out the error in the log. LVS configuration, testing will take a relatively long time, LVS on the network dependence is relatively large. 3, can bear high load pressure and stability, in the case of hardware is not bad generally can support tens of thousands of times the

Windows Azure Platform Family of articles CatalogNote: If Azure is facing a customer that is only an enterprise customer, an enterprise customer accessing the Internet with a NAT device, because multiple clients use the same source IP address, can cause a single server to be under a lot of stress.This feature has been out for some time, the author here to do a little note.　　Readers familiar with the Azure platform know that the rules for Azure load

Centos + nginx configure server load balancer from scratch, centosng.pdf. Centos + nginx configure server load balancer from scratch. centosnginxnginx server load balancer understands that nginx is a lightweight and high-performan

implementation and configuration and maintenance process is more complex, relatively speaking, nginx/haproxy+ Keepalived is a lot easier. HAProxyfeatures of Haproxy: Haproxy is also supported for virtual hosts. The advantages of haproxy can be supplemented with some of Nginx's shortcomings, such as supporting session retention, cookie guidance, and the ability to detect the status of the backend server by obtaining the specified URL. Haproxy similar to LVS, itself is just

Generally, server load balancer distributes client requests to various real backend servers to achieve server load balancer. Another method is to use two servers, one as the Master and the other as the hot backup ), Generally, server load

, support the URL detection backend server problem detection will be very good to help.4, it is just like the LVS, itself is only a load balancer software, simply from the efficiency of the haproxy more than Nginx has a better load balancing speed, in concurrent processing is better than nginx.5, Haproxy can load balan
