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.

8. How it started…

9. How it started…
• MVP Summit 2011
– Wade Wegner talks about his
homebrewing hobby
• MVP Summit 2012
– Wade Wegner talks about his
homebrewing hobby
• Convinced!

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

11. The process
Wait for fermentation to complete

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

13. Difficult part…
Wait at least 6 weeks
for it to age

14. Maarten…
What does this have
to do with Windows Azure?

15. Azurifying the home brewer
www.BrewBuddy.net

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

17. BrewBuddy

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

20. 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

21. Windows Azure Web Sites

26. A perfect ramp-up!
• Start small
– Web Sites are cheap
– Scale to 3 reserved instances
• Grow big!
– Hosted Service – PaaS
– Scale at will

28. Connecting sensors
Service Bus
& Access Control Service

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

30. Windows Azure Service Bus Relay

Client

31. Topics and subscriptions
Sensor

32. Characteristics
• Workers can scale independently
• Workers can fail independently
• Sensors connect to service bus
directly
– No layer in between
– Cheaper

33. 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

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

38. <french>Make everyone API!</french>
We need an API

39. What is an API?
• Software-to-Software interface
• Contract between software and
developers
– Functionalities, constraints (technical /
legal) Programming instructions and
standards
• Open services to other software

40. Do we need one?
• Reach to scale
• Smartphone generation
• BYOD with 3 screens: phone, tablet and
computer
• Flexibility in providing content
• You have data to share
• Integration

41. Build Richer Apps
Reach More Clients

42. ASP.NET Web API
• Part of ASP.NET MVC 4
• Framework to build HTTP Services (REST)
• Solid features
– Modern HTTP programming model
– Content negotiation (e.g. Xml, json, ...)
– Query composition (OData query support)
– Model binding and validation (conversion to .NET objects)
– Routes
– Filters (e.g. Validation, exception handling, ...)
– And more!

43. ASP.NET Web API
Let’s craft a quick API
demo

44. What about authN / authZ?
• API access through OAuth2
• Access Control Service to the rescue!
• Client authorized in BrewBuddy.net
• Access/refresh tokens through ACS

45. What about authN / authZ?
API Consumer BrewBuddy.net
client_id and client_secret access API
authorize Initial authorization (yes/no)

access/refresh token register delegation
Access Control Service

47. Takeaways

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