) known for providing audio and video services to RealPlayer, The world's largest open source website (sourceforge.net). Using LVS to set up a server cluster system has three parts, the most front-end load balancer layer, with load balancer, the middle of the server group layer, with server array, the bottom of the dat

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load

"I am a novice in load balancing, the documentation is too complex and needs getting started. ”"I want to initialize a load balancer for the first time in life and need guidance. ”If you are a novice, if you first touch the load balancer, if its name is Citrix NetScaler, the

-demand services, and so on, there are many more famous sites and organizations are using LVS set up the cluster system, For example: The Linux portal (www.linux.com), real Company (www.real.com), the world's largest open source website (sourceforge.net), which provides audio and video services to RealPlayer. The LVS architecture uses the LVS to set up the server cluster system has three parts: the most front-end load balancing layer, with

node, however, the disadvantage is that URL detection is not supported;6. nginx only supports HTTP and email, which is much smaller in the scope of application, which is weak;7. nginx is not only an excellent Load balancer/reverse proxy software, but also a powerful Web application server. Lnmp is also a very popular Web architecture. It has a lot to fight against the most popular lamp architecture in the
