Windows Azure Websites

Service Bus & Access Control Service (ACS)

We need an API

Q&A

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

Let’s do it!

The process

Get your kettle clean Add & boil ingredients Pour in kettle Add yeast Rinse

Brewing = cleaning!

The process

Wait for fermentation to complete

The process

Pour into another kettle 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?

BrewBuddy.netSocial brewing!

BrewBuddy View public recipes

Manage your own recipes

Manage your own brews

Service Bus &Access Control ServiceConnecting sensors

Windows Azure Service Bus 2 features Relay Queues, Topics, Subscriptions

Client Service

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

We need an API

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)

Twitter & FacebookBy show of hands

Make everyone API(as the French say)

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)

Expose services to 3rd parties

Valuable

Flexible

Managed

Supported

Have a plan

Reach 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!

Be detailed! Think about RFC 2324 (HTCPCP)

ASP.NET Web APILet’s craft a quick API

A lot of public API’s…

“your API consumer isn’t really your user,but an application acting on behalf of a user”

(or: API consumer != user)

So they do this!

In our own API, authN / authZ API access using OAuth2

Access Control Service to the rescue!

Client authorized in BrewBuddy.net

Access/refresh tokens through ACS

What about authN / authZ?

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
