not receive large traffic impact.5, the application of a wide range, because LVS work in the 4 layer, so it can almost all applications to do load balancing, including HTTP, database, online chat room and so on.The disadvantages of LVS are:1, the software itself does not support regular expression processing, can not do static and dynamic separation , and now many sites in this area have a strong demand, this is the advantage of nginx/haproxy+keepali

(source IP, Destination IP, Protocol). This is the same client-initiated request that points to the same Azure destination server. In this way, you can keep the session. As shown in the following:　　　　Preparation: Please refer to [New portal]windows Azure Virtual Machine (9) Virtual machine high availability and automatic load balancing (below), create the follow

Three major software load balancer comparisons (LVS, Nginx, HAproxy)(Information from the network, made part of the supplementary instructions)LVS:1. Strong anti-load capability, high performance, can reach F5 60%, low memory and CPU resource consumption2. Work in the Network 4 layer, through the VRRP protocol (for Proxy only), the specific traffic is handled by

, the communication volume is moved to another host. Network Load Balancing Configuration OverviewNetwork load balancing is a network driver for Windows 2000. Its operations are transparent to TCP/IP network stacks. To ensure optimal network performance, network load balancing usually uses a network adapter to handle customer-to-cluster traffic, while other netwo

is a virtual IP address of keepalived. It is an external public IP address and also an IP address pointed to by DNS. Therefore, when designing the website architecture, you must apply for an external IP address from your IDC. 11. during actual project implementation, we found that LVS and nginx have excellent support for HTTPS, especially LVS, which is easier to process. 12. During LVS + keepalived and nginx + keepalived troubleshooting, both of them

, packet disinfection, and other functions ｡ The following are the main features of F5 BIG-IP as an HTTP Load balancer: ① F5 BIG-IP provides 12 flexible algorithms to distribute all traffic evenly to each server, but to the user, just a virtual server ｡ (2) F5 BIG-IP can confirm whether the application can return the corresponding data to the request. If a server

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
