The process
 Get your kegs clean
 Add & boil ingredients
 Pour in keg
 Add yeast
 Rinse
AUGUST 30, 2012 | SLIDE 9

The process
Wait for fermentation to complete
AUGUST 30, 2012 | SLIDE 10

The process
 Pour into another keg
 Rinse
 Wait another week
 Bottling time!
AUGUST 30, 2012 | SLIDE 11

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

What does this have
to do with Windows Azure?
AUGUST 30, 2012 | SLIDE 13

Azurifying the home brewer

AUGUST 30, 2012 | SLIDE 14

BrewBuddy
 View public recipes
 Manage your own recipes
 Manage your own brews
 Monitor brew fermentation

Scale-fast has just become more interesting
WINDOWS AZURE WEB SITES
AUGUST 30, 2012 | SLIDE 18

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
AUGUST 30, 2012 | SLIDE 19

A perfect ramp-up!
 Start small
 Web Sites are cheap
 Scale to 3 reserved instances
 Grow big!
 Hosted Service – PaaS
 Scale at will
AUGUST 30, 2012 | SLIDE 25

Windows Azure Web Sites

AUGUST 30, 2012 | SLIDE 26

Connecting sensors
SERVICE BUS &
ACCESS CONTROL SERVICE
AUGUST 30, 2012 | SLIDE 27

Windows Azure Service Bus
 2 features
 Relay
 Queues, Topics, Subscriptions
AUGUST 30, 2012 | SLIDE 28

Windows Azure Service Bus Relay

AUGUST 30, 2012 | SLIDE 29

AUGUST 30, 2012 | SLIDE 30

Characteristics
 Workers can scale independently
 Workers can fail independently
 Sensors connect to service bus directly
 No layer in between
 Cheaper
AUGUST 30, 2012 | SLIDE 31

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

<french>Make everyone API!</french>
WE NEED AN API
AUGUST 30, 2012 | SLIDE 37

Consuming the web
 2000-2008: Desktop browser
 2008-2012: Mobile browser
 2008-2012: iPhone and Android apps
 2010-2014: Tablets, tablets, tablets
 2014-2016: Your fridge (Internet of Things)

AUGUST 30, 2012 | SLIDE 40

Make everyone API
(as the French say)
AUGUST 30, 2012 | SLIDE 41

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)
AUGUST 30, 2012 | SLIDE 42

Expose services to 3rd parties
 Valuable
 Flexible
 Managed
 Supported
 Have a plan
AUGUST 30, 2012 | SLIDE 43

Reach More Clients
AUGUST 30, 2012 | SLIDE 44

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!
AUGUST 30, 2012 | SLIDE 45

Be detailed!
Think about RFC 2324 (HTCPCP)
AUGUST 30, 2012 | SLIDE 46

ASP.NET Web API
Let’s craft a quick API
demo
AUGUST 30, 2012 | SLIDE 47

What about authN / authZ?
 API access through OAuth2
 Access Control Service to the rescue!
 Client authorized in BrewBuddy.net
 Access/refresh tokens through ACS
AUGUST 30, 2012 | SLIDE 48

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
AUGUST 30, 2012 | SLIDE 49

TAKEAWAYS
AUGUST 30, 2012 | SLIDE 51

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
