Virtual Servers Load Balance

How Virtual Servers help in Load Balancing?

With the rise in HTTP request being sent to the web server, the single server may not be able to serve all the request band with the same priority. As the response time increases there is an overall effect towards the end-user visitor. So in order not to miss the potential visitors, often virtual servers are being added and configured into the system to distribute the load balance among them.

Proxy Server Intruders Monitoring

Now under these circumstances we need a proxy server through which all the request are being bypassed. The role of proxy server in the virtual servers system is to monitor all the HTTP request and distribute it equally amongst the different servers and thus reduce the response time.

Methods employed by Proxy Servers

• When working with the virtual servers, whenever we make any changes to any file the we need to upload it on all the servers,i.e., we keep the same version of files on all the different system. This is the simplest method being employed by lots of organization.
• Aliter way is to design an appropriate algorithm and the break all the server request files into different categories and upload them on different servers. Now proxy server will do the request forward as per the algorithm. Here when we employ the web server caching option, it gives a better output.
• All the servers can be categorized on basis of the country, then alphanumeric characters being request in the URL.
• We can employ third level virtual servers also and so on as per the traffic and this can be implemented on the required category only. Such is the importance of the categorization.
• Even the proxy servers themselves can be categorized in this fashion. So as to increase the effectiveness of the complete infrastructure.

All these are special part of parallel processing algorithms.
