This is a great tool for anyone playing with Windows Azure who would like to avoid surprises on their credit card :-) It has only had 85 downloads – I suspect we see that many folks caught out by a demo/poc being “left on” per week :)

Project Description

The GreyBox application is designed to alert a user if their Windows Azure compute services are currently running, or are even simply deployed. Great for Azure speakers and POCs you don't want left running.

With the popularity of Windows Azure growing more Microsoft and third party speakers are talking about Azure to your communities, classes and clients. These speakers are often utilizing their own MSDN or partner benefits for Microsoft Azure services. Unexpected costs can arise if Azure compute services are accidentally left running in the cloud after a presentation or class.

The GreyBox application is designed to alert a user if their Windows Azure compute services are currently running, or are even simply deployed. The names GreyBox comes from the concept of wanting to have the compute service slots empty, which the Azure Portal represents as a graphical grey box.
