brewing beer with windows azure - aspconf
DESCRIPTION
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.TRANSCRIPT

How it started…
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
The process
Wait for fermentation to complete
The process
• Pour into another keg• Rinse• Wait another week• Bottling time!
Difficult part…
Wait at least 6 weeks for it to age

What does this haveto do with Windows Azure?
www.BrewBuddy.netAzurifying the home brewer
BrewBuddy
• View public recipes• Manage your own recipes• Manage your own brews• Monitor brew fermentation

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

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

Service Bus& Access Control Service
Connecting sensors
Windows Azure Service Bus
• 2 features–Relay–Queues, Topics, Subscriptions

Client Service

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

How do you link a sensor?
• Every sensor has its sensor ID• Add it as an identity to ACS• Grant a “Send” claim
demoRegistering a sensor with Access Control Service

We need an API<french>Make everyone API!</french>
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 developers (public or private)
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
Build Richer AppsReach More Clients
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!
demoLet’s craft a quick API
ASP.NET Web API
What about authN / authZ?
• API access through OAuth2• Access Control Service to the rescue!• Client authorized in BrewBuddy.net• Access/refresh tokens through ACS

Takeaways
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
