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 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.

7. How we got started…

8. How we got started…
• MVP Summit 2011
– Wade Wegner tells us about his hobby
• MVP Summit 2012
– Wade Wegner tells us about his hobby
• We nodded at each other

9. The process
• Get your kegs clean
• Add & cook ingredients
• Pour in keg
• Add yeast
• Rinse

10. Difficult part # 1…
Wait for fermentation to complete

11. The process
• Pour into another keg
• Rinse
• Wait another week
• Bottling time!

12. Difficult part # 2…
Wait 6 weeks
for it to age

13. Panos, Maarten…
What the f* does this have
to do with Windows Azure?

14. Azurifying the home brewer

15. BrewBuddy
• View public recipes
• Manage your own recipes
• Manage your own brews
• Monitor brew fermentation

18. Scale-fast has just become more interesting
Windows Azure Web Sites

19. Windows Azure Web Sites
 Build with ASP.NET, Node.js or PHP
 Deploy in seconds with FTP, Git or TFS
 Start for free, scale up as your traffic
grows

26. Connecting sensors
Service Bus
& Access Control Service

27. Windows Azure Service Bus
• 2 features
– Relay
– Queues, Topics, Subscriptions

28. Topic populated by sensors
Sensor

29. Characteristics
• Workers can scale independently
– Loosely coupled architecture
• Sensors connect to service bus
directly
– No layer in between

30. 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

31. Access Control Service

33. How do you link a sensor?
• Every sensor has its sensor ID
• Add it as an identity to ACS
• Grant a “Send” claim

35. A step further!
• Custom application
• Consume the data from devices
• Exchange information with the app
• In other words, an API

36. ASP.NET MVC Web API
• <frenglish>Being h-appy about the
API </frenglish>
• Use it to build your public API
• Secure it using claims from ACS

37. ASP.NET MVC Web API
• Easy to add, it’s just a another project
• Supports all cool stuff, like JSON,
XML etc.
• It’s MVC, that means awesome!

38. Coding took an arrow to the knee

40. Takeaways

41. Keep in mind…
• Web Sites start cheap / scale fast
• Combine at will (IaaS, PaaS, SaaS)
• Service bus for asynchrony and scale
• Access Control for devices
• Web API
