Web Server Farm Design Using Personal Computer (PC) Desktop

Web server is a service system that has been used for various purposes. Not just popular websites like Google, Facebook, Twitter, and Amazon only. Even Computer Assisted Test (CAT), Computer Based Test (CBT) and Learning Management Systems (LMS) are now web-based. But not all are able to provide server computers to run web server services for one reason or another. The web server service provider utilizes the Desktop Personal Computer (PC) to replace the server computer's task. Desktop PC is not designed to run server functions. A lot of requests will cause the server on Desktop PC to overload and cause server down. It takes two or more servers for the server to be shared. Scalable web server is a set of multiple servers that are connected and used to handle requests from Hypertext Transfer Protocol (HTTP) protocol users on a large scale. Implementing the Web Server Farm or Clustering Web Server and Load Balancer, as well as High Availability architecture, are expected to overload the server overload problem. From Load Balancer test result concluded that Least Connection algorithm better than Round Robin algorithm. The average time of Downtime in High Availability or failover testing is 6.587 seconds.
