How to determine cost of cloud migration

How do you get a meaningful estimate for the cost of migrating applications to the cloud? Previously, I've used the scratch head and guess method based on past usage and storage needs, but it hasn't always been very accurate.

Here's an article that might help get you started.

Understanding Enterprise-to-Cloud Migration Costs and Risks

"Migrating to Infrastructure as a Service (IaaS) is an attractive option for corporations that want to shift from a capital expense to a pay-as-you go model. Regardless of the business driver for cloud computing, of which there are many including reducing costs and adding nimbleness, large enterprises are now faced with re-evaluating their core IT assets with an eye towards enterprise-to-cloud migration for improving business efficiencies. However, beyond qualitatively appreciating the benefits of cloud computing, IT executives lack the ability to quantitatively assess the risk-reward structure of which application should be migrated from the enterprise to a cloud. Without having a quantifiable impact assessment of migrating enterprise resources to a cloud, enterprises are faced with ad-hoc decisions during their cloud migration process."

Hello friends,

Cloud computing has business executives salivating at the savings potential and demanding that their CTOs jump on the bandwagon and get to the cloud.
But, managers should make sure they understand the hidden cost involved, according to a study by the Information Systems Audit and Control Association (ISACA), called "Calculating Cloud ROI: From the Customer Perspective."
"Cloud computing makes it easy to offer the same self-service that people love when they turn on their lights or air-conditioning -- it’s on-demand and pay as you go. In reality, cloud computing is like every other innovation," says Marc Vael, CISA, CISM, CGEIT, CRISC, international vice president of ISACA. "Security, cost and complexity don’t disappear -- they just need to be managed and accounted for."

Thanks and Regards,

I would think you can at least get in the ball park with your head scratch method.  Tom's had an ok piece on this a few months ago.  It could give you some tips.  http://www.tomsitpro.com/articles/cloud_migration.-iaas-public_cloud-pri...
