citrix netscaler

The main advantages of the cluster system are:High scalability:High availability: One node in a cluster fails, and its tasks can be passed to other nodes. Can effectively prevent single point of failure.High performance: Load Balancing clusters allow the system to access more users at the same time.Cost-Effective: high-performance systems can be constructed with inexpensive, industry-standard hardwareCluster Type:The three most common types of clusters:Load Balancer cluster: LB (Load Balancing)H

Lvs:linux Virtual ServerA free software project initiated by Dr. Zhangwensong, whose official site is www.linuxvirtualserver.org.Now LVS is already part of the Linux standard kernel, Prior to the Linux2.4 kernel, the LVS had to be recompiled to support the LVS function module, but since the Linux2.4 kernel, the various functions of LVS have been built-in, without any patching of the kernel, and the functions provided by LVS can be used directly.LVS is a software implementation scheme for LB clus

using software to load balance, the disadvantage is that the scheme is more complex, not strong enough, it is difficult to reuse (because the logic of the coordination request is mixed in the business system). In this respect, Larson in the article in a continuous way to raise questions, in order to strengthen their non-recognition of this program attitude: Is it attractive because it is the simplest solution? Usually, No. Is it seductive because it's the most robust? Sadly, No. Is it

Install and configure Nginx in LinuxApplication scenarios For a large website, Server Load balancer is an eternal topic. As its name suggests, Server Load balancer distributes loads to different service units, ensuring service availability and fast response, provide a good user experience.

After a few days of my groping and testingThe steps to quickly build a virtual desktop are as follows:1, make windows2008r2 template (install Xentools, dotNet4.0, dotNet4.5, SQLSERVER2008R2 installation preparation, turn off IE security, turn off the firewall, and then use the Sysprep package, go to the template)2, using the template to produce 3 virtual machines named AD50,DB49,XD55,PVS56 (install domain control, the XD55 and PVS56 are joined to the domain, there is a database installed)3, inst

The most commonly used is F5 and Citrix NetScaler Load balancing is divided into global load balancing and local load balancing. Load balancing is the load balancing of the local server group, and the global load balancing refers to the load balancing of the server groups placed in different geographical locations and different network structures. Circular DNS Is the next IP in the IP loop list each time t
