I placed a lot of effort on Cloud Computing engagement and had tours around the country. Piling my mileage

First off of everthing, I demo my compiz 3D desktop enabled Ubuntu 9.04 to show off how we live in a pure open source environment without having to touch any of Microsoft.

Get back to our topic. Last week, I visited one of largest mobile device / equipment manufacturer to discuss how a Cloud Computing could transform customer’s IT. We spent an hour to talk about Return of Investment (ROI). To list what are supposed in consideration of an ROI

• Hardware
• Image Instance – build, migration, administration
• Software – non-free operating system and hypervisor. If Xen, or KVM being used on LAMP, the cost is close to zero. And all software to build a Cloud environment with licensing and maintenance.
• Labor – build and operate a Cloud environment
• Provisioning Process – time taken to complete provision

Input the above consideration comes out in 3 charts as the following (the data is under a certain assumption and might vary in different environment) :

• Comparison of without- cloud and with- cloud

• Categorized

• Cost in Transformation

The information reflects a scope of ROI to be analyzed and doesn’t have to mean this is a mandatory.
