Are you the one to decide on implementing your next project based on public cloud platforms such as Windows Azure? Is it going to be HTML5, Flash or Silverlight for your rich end-user interface? Have you thought about the costs running on cloud services that seem cheaper than hosting on your own hardware? What other open questions and second thoughts do you have that keep you from making a decision?
