netscaler load balancing methods

Citrix NetScaler Load Balancing algorithmhttp://blog.51cto.com/caojin/1926308As we all know, Citrix NetScaler, which delivers products as a new generation of applications, has the industry's leading data control, application delivery capabilities, but as one of the fundamental content of ADC capabilities, it is not pos

NetScaler is the industry-leading service delivery platform. NetScaler supports a wide range of platforms with comprehensive application security settings, acceleration, and load balancing (including GSLB) capabilities. The main advantages of NetScaler are as follows:1) Powe

As more and more application architectures are decoupled and distributed, the requirements and dependencies of load balancer devices are increasing while the component scale-out capability increases, and the load-balancing devices are required to have strong scale-out capability. Load

, so that more people have the opportunity to build their own clusters. LVS provides three forwarding mechanisms (Traffic forward mechanism) and four load-balancing methods. Traffic forward Mechanism) 　　Three different forwarding mechanisms create an LVS host Nat virtual host virtual server via Network Address TranslationIP tunneling virtual host virtual server v

There are many ways to load balance the web, and here are a few common load-balancing methods. 1. User manual Selection method This is an older way. Load balancing is achieved by providing different lines and different server conn

and block occupy about 150 bytes of space. Therefore, if there are million files and each occupies one block, at least MB of memory is required; At present, millions of files are still feasible. When it is extended to billions, it is difficult to achieve the previous hardware level; 2) The number of map tasks is determined by the split. When mapreduce processes a large number of small files, too many map tasks will be generated, and the thread management overhead will be the job time; For

cannot detect it and will not forward the request. The common advantage of R-proxy and mod_jk is that only Apache can be deployed on the public network, saving public IP Address resources. Apache can handle static web pages through settings, so Tomcat can handle dynamic requests such as JSP and servlet. The common disadvantage is that if the front-end Apache proxy server stops running, all cluster services cannot be provided externally. R-proxy and mod_jk can be used to select an optimal effect

forwarded to the backend server in the four-layer mode, whereas in the seven-tier mode these SYN attacks are naturally cut off on the load-balanced device without affecting the normal operation of the backend servers. In addition, the load Balancer device can set up various strategies at seven layers, filter specific messages, such as SQL injection and other application-level attack

In addition, the load Balancer device can set up various strategies at seven layers, filter specific messages, such as SQL injection and other application-level attack methods, and further improve the overall security of the system from the application level.
