I just had a chance to look at the newly release Windows Azure pricing Calculator … It rocks and is now live here: http://www.microsoft.com/windowsazure/pricing-calculator/.
This pricing calculator lets you pick compute, database, storage, bandwidth, CDN and Service Bus capacity based on your needs. Along with predicting your expected monthly costs, the pricing calculator then recommends the most cost effective offer for you to purchase Windows Azure platform services.
Nice functionality, so along with already some time ago released and more sophisticated TCO calculator, now you can easily assess the monetary benefits of moving to the Microsoft Public Cloud!
