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

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

11.
The processWait 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

Maarten… What does this haveto do with Windows Azure?

Azurifying the home brewerwww.BrewBuddy.net

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

Scale-fast has just become more interestingWindows 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

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

Connecting sensorsService Bus& Access Control Service

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

30.
Windows Azure Service Bus Relay 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 AppsReach 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 APIdemo

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) API implementation access/refresh token register delegation Access Control Service Access/Refresh Token

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
