Corporate Concerns

> Minimize the cost/effort to move to Azure

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

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
