Brewing BeerTurn water into beer

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

Windows Azure Service Bus Relay

Client Service

relay

Topics and subscriptions

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

Linking a sensor to a brew

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
