Inspired by one of the Windows Azure gods (Wade Wegner), Maarten and Panos decided to order a homebrewing starter kit. Being total cloud fanboys, they decided to hook their delicious creations to the cloud. Join us and discover how you can connect a variety of devices (like *duino) and USB temperature sensors to Windows Azure to monitor brewing and fermentation temperatures. We'll show you how to do distributed brewing in this fun yet practical session on an interesting use case for the cloud: beer.
