ADADFS Server
What did we find?> Authentication – ADFS server against corporate AD in
our DC> Authorization – ADFS custom claim to make the
authorization decision> Data Sync – SSIS to push subset of rows and columns
to SQL Azure> Security/Audit – specific to each organization and
industry for data and operations> Application Integration – use of ADFS Passive Fed
allowed Web SSO model between apps in different locations
> Operations/Management – cannot use Windows Event Log and SCOM
> Cost – very little code change to existing application; quick time to deliver
Why is this cool?> You already have the skills you need
(Visual Studio, SSIS)> No infrastructure required! (assuming
you already have ADFS)> Don’t worry about the plumbing, just
build the application> Microsoft is providing the tooling and
guidance to reduce the barrier to leveraging Azure

Application Overview> Sales Tax Office
> Real-time sales tax calculation> Multiple business entities, multiple ERP
modules or even different ERP systems> Sales Tax Office works behind the
scenes with minimal user interaction

Challenges> Plex (3rd party libraries)> State management> Performance> Security> Database migration> Database partitioning
Lessons Learned> Be prepared to sacrifice hardware and software control
in exchange for lower maintenance costs.> Log, log and log. Verbose logging will make application
troubleshooting easier.> Design your systems for scaling out, not up. If dealing
w/ an existing system some code refactoring may be necessary.
> Use database partitioning techniques (the database also has to scale out due to the 10 GB limitation on the db size).
> Plan your data migration.> Store sensitive customer data on premises.> Use proper State management techniques - think
“Stateless”.

Overview> Application Overview
> Build a video and audio transcoding solution based on the Windows Azure cloud computing platform
> Key Business Goals> Decrease transcoding costs> Provide greater scalability> Greater Geographic distribution
> Platform Adoption Driver> The key factor driving Azure adoption is to be
able to cost effectively respond to changing customer demands and volumes

Challenges> Finding and implementing a
inexpensive and reliable software based encoding, and implementing it in the cloud
> Determining an algorithm for auto scaling
> Working with pre-release SDKs, as they tend to change
> Deployment and release process
Benefits> Significant cost savings versus existing
transcoding hardware and software> Ability to quickly and cheaply respond to
varying demand levels> Ability to easily provide geographically
relevant solutions to our customers
