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 existing application
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

Migrating data to SQL AzureSynchronizing SQL and SQL Azure
ASP.NET Membership & Roles• Will not work out of the box!
• Some incompatible SQL
• Updated scripts and aspnet_regqslazure.exe• http://support.microsoft.com/default.aspx/kb/2006191

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
http://www.cloudberrylab.com• Azure Storage Explorer
http://azurestorageexplorer.codeplex.com/• Online
http://myazurestorage.com • Visual Studio 2010 tools

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
