Inspired by one of the Windows Azure gods (Wade Wegner), Maarten decided to order a homebrewing starter kit. Being a total cloud fanboy, he decided to hook those delicious creations to the cloud. Join Maarten 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. He'll show you how to do distributed brewing in this fun yet practical session on an interesting use case for the cloud: beer.

30. Characteristics
 Workers can scale independently
 Workers can fail independently
 Sensors connect to service bus directly
 No layer in between
 Cheaper
AUGUST 30, 2012 | SLIDE 31

31. What about authN / authZ?
 Access Control Service to the rescue!
 SB authenticates clients over ACS
 ACS provides “Send” claim to sensor
 Claims can be granted/revoked easily
