The Windows Azure Platform• Windows Azure• SQL Azure• Windows Azure platform AppFabric• Microsoft Codename “Dallas”• Microsoft Codename “Sydney”
Windows Azure
• Flexible application hosting• Lights-out service management
• Provide code & service model, hit ENTER• Storage at massive scale
• Blobs, tables, queues
Compute StorageManagement
Windows Azure
Storage options• Blobs, tables, queues• Windows Azure Drive (a.k.a. XDrive)
• Virtual NTFS volume that can be mounted• .vhd format• Use existing NTFS API’s• Easier migration• Stored on blob storage provides quick mount/unmount in
other VM
SQL Azure
• Relational database as a service• Highly available, automatically maintained
• Extension of the SQL Server Data Platform
Database
Reporting Business Analytics Data Sync
SQL Azure• Relational database, provided as a service• Highly symmetrical development and tooling experience (use
TDS protocol and T-SQL)• Highly scaled out, on commodity hardware• Built on the SQL Server technology foundation• High availability, DB provisioning, and DB management are
provided by the service
Windows Azure AppFabric
• Secure connections between services• Across organizational boundaries
• Claims-based access control
ServiceBus
AccessControl
Service Bus Overview
Windows Azure AppFabric - Service Bus• Securely connect applications
• Over the internet• Across any network topology (= across firewalls!)• Across organizational boundaries
• Primary application patterns• Eventing:
• Notify applications and/or devices• Service Remoting:
• Securely project on-premises services out to the cloud• Tunneling:
• App-to-app communication with NAT/Firewall traversal
Microsoft Codename “Dallas”
• Content brokerage and discovery platform • Available as a CTP

An existingapplication
Time Tracker• Originated from the ASP.NET starter kit
http://www.asp.net/downloads/starter-kits/time-tracker
• Small modifications:• List of projects from internal billing system• Time registration can have an attachment
DEMO
TimeTracker – On-premise
Time Tracker• There are some problems with it...
• Running on 2 web servers that are > 2 years old, nearing EOL
• Looking to buy new hardware• Looking to deploy the application in a cloud
• Spikes near the end of each month, reducing performance• Looking to buy additional hardware• Looking to deploy the application in the cloud
• They do have this “seamless scaling” thing, right?

Challenges• Security?
• Forms based• Claims based (AppFabric
access control service)• Availability & scalability out-of-
the-box• Still keep session state in
mind• Specify “upgrade domains”
• Logging & tracing• System.Diagnostics.Trace• Performance counters• All stored on blob storage, not
real-time!
• Operating system• Windows Azure Cloud OS 1.0 –
1.1 – x.x• See MSDN for patches and
hotfixes in each OS version• New cost model
• Pay-per-use• Allow for scale-up and scale-
down

TimeTracker on steroids!• Our company decided to go for Windows Azure• New migration track started
• Learn about Windows Azure• Support deployment on Windows Azure• Store data in SQL Azure• Store attachments on blob storage• Somehow connect with the billing system to get a list of
project names• Deploy
Support deployment on Windows Azure• Convert the TimeTracker solution to a Cloud Service solution• Make sure it can be packaged for deployment• Make sure it runs on Development Fabric
• Requirements:• IIS7• Visual Studio• Windows Azure Tools for Microsoft Visual Studio• Windows Azure SDK (shipped with the above)

Store data in SQL Azure• There is a database on-premise in SQL Server
• Schema should be migrated• Data should be migrated
• Requirements:• Native SQL client• SQL Management Studio
Migrating schema and data• SQL Azure Migration Wizard

ASP.NET Membership & Roles• Will not work out of the box!
• Some incompatible SQL

Store attachments on blob storage• Attachments currently stored on the web server• Windows Azure server storage not guaranteed to survive
• There’s an option for that...• ...but it will still fail in some situations
• Ideal candidate: blob storage
• Requirements:• Windows Azure SDK• A tool to browse storage and see if it works
Tools to see if it works• CloudBerryLab Explorer

project names• Deploy
Connect with the billing system• List of projects comes from on-premise billing system• TimeTracker will be in the cloud
• Requirements:• Expose the billing system to the Internet• Connect to it
Service Bus Overview
Connect with the billing system• List of projects comes from on-premise billing system• TimeTracker will be in the cloud• Communication will happen over the AppFabric service bus
• Requirements:• Visual Studio• AppFabric SDK
DEMO
Using AppFabric service bus
Another option…• Billing system WCF configuration was changed• If that’s not possible: PortBridge to the rescue!

What to remember?• Windows Azure is
• Operating system (computing & storage)• SQL Azure• AppFabric• Your application and skills
• Hybrid applications are possible
• It’s not that hard to do
