There are many good reasons for companies to virtualise environments, but make sure you do your homework, planning and don’t believe everything consultants tell you. A virtualisation case study of how to avoid cost blowouts follows.
The company in this case study may not be
typical, but what is typical is that there is no typical company. Does
that make sense?
Company X has a medium sized presence in the financial industry within
Australia, but is only the Asia Pacific arm of a much larger global
entity. X main offering is financial software services, the majority
of which run on IBM Z series mainframes, housed in secure IBM managed
data centres.
For some years however X has provided a browser based GUI (Graphical User Interface) front end to the mainframe application.
This system was traditionally not greatly resourced, and as such was
plonked on three (Production, Prod backup and Development) X series
servers. Running Windows Server 2000 and IIS and housing all client
web sites on a single box.
As time progressed, it became obvious that clients wanted to shift away
from the traditional 3270 (green screen) access to the GUI offering.
Added to this pressure was the arrival of new Java based applications,
adding to the X stable of software on offer to clients. These
applications ideally needed to be run in a Linux/Apache Tomcat
environment.
As such, resources were given to spruce up the mid-range environment. So what happened?
