Great Explanation of Azure Storage Costs
Brad Calder, from the Microsoft Azure Storage Team, posted a blog entry on the Azure Storage Team Blog describing the cost structure for the Azure Storage in great detail. This is a great reference that shows just how the storage space is calculated, explains what a transaction is and when you will and will not be charged for bandwidth.
If you are looking to use Azure Storage you should definitely check this post out: “Understanding Windows Azure Storage Billing – Bandwidth, Transactions, and Capacity ”.
This is great detail. I hope the guys over at the AppFabric Team see this and put up something similar to explain Connections, Bandwidth and Transactions for their services as well.
