Following a discussion on the OzAzure mailing list I went off hunting for what others had put together on calculating the ROI for building or migrating to Windows Azure. I’m not sure how I didn’t come across the Azure ROI Calculator earlier in my hunt for information on Windows Azure as it is the top 10 or so links when you search for Azure ROI. Anyhow, it provides a neat little Silverlight application for doing a basic ROI for cloud applications.
Of course where this gets interesting is when you compare it to the other offerings/alternatives in cloud space. I’m hoping that others out there will share their thoughts around costing the cloud.
