METHOD FOR AUTO-SCALING OF WEB SERVER AND WEB APPLICATION SERVER AND WAS ADMINISTRATING SERVER USING THE SAME

摘要

A method for auto-scaling at least one web server and at least one WAS (Web Application Server) is provided. The method includes a WAS administrating server grouping, as a first service group, both at least one first web server and at least one first WAS, which are connected with each other to provide a first application service, and grouping, as a second service group, both at least one second web server and at least one second WAS, which are connected with each other to provide a second application service, to thereby create at least two groups each of which includes at least its corresponding pair of web server and WAS, and the WAS administrating server allowing each of the grouped pairs of the web servers and the WAS's to be scaled out or scaled in, independently, by a process of scaling-out or scaling-in.
