f5 load balancer features

First, the problems encounteredWhen we deploy a Web application with an IIS server, when many users have high concurrent access, the client responds very slowly and the customer experience is poor, because when IIS accepts a client request, it creates a thread that consumes large memory when the thread reaches thousands of. At the same time, because these threads are switching, the CPU usage is also high, which makes IIS more difficult to perform. So how do we solve this problem? Second, how t

QoS function, the router provides different levels of priority processing capabilities for data exchange for specific business applications.　　3. Use layer-4 switching technology to achieve server load balancingThe following design comes from the practical application of the network center of a Network Education College in a university. The layer-4 switch of Alteon provides Server Load

cheap and effective method to expand server bandwidth and increase server throughput. It enhances network data processing capabilities and improves network flexibility and availability. "Server Load balancer" can be seen everywhere in daily life. At the peak of a supermarket, only 10 customers can be served. If 20 customers need services during the activity, they may be queued up, in this way, the shopping

Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind has the reverse proxy function software. Fortunately its settings are not very troublesome

HAProxy is a proxy software that provides high availability, server load balancer, and TCP and HTTP applications, HAProxy is a completely free proxy solution that provides TCP and HTTP applications quickly and reliably with HAProxy. HAProxy is applicable to websites with large loads. these sites usually need session persistence or layer-7 processing. HAProxy supports tens of thousands of concurrent connecti

I used nginx to implement the website load balancing test. In windows, IIS performs load measurement. If your website traffic (pv) is getting higher and higher, and one server is no longer able to withstand the traffic pressure, increase the number of WEB servers for load. Website load can be achieved by buying hardw

Lvs-nat model: Similar to Dnat, but supports multi-target forwarding, which is multi-objective DnatIt is forwarded by modifying the destination address of the request message to a certain RS rip selected by the scheduling algorithm.Architectural Features:(1) RS should use a private address, that is, RIP should be a private address, each RS gateway must point to the dip(2) The request message and the response message are forwarded through the Director;

Why do I need to load balance the tomcat server?The Tomcat server acts as a Web server with a number of concurrent numbers between 300-500, and if more than 500 concurrency occurs, Tomcat does not respond to new requests and severely affects the operation of the site. At the same time, if the traffic is very large, the number of threads in Tomcat is increasing. As a result, it takes up a lot of memory and when there is a memory overflow, you need to r
