Migrating an ASP.NET MVC application called Nerd Dinner to Windows Azure involves converting it to a web role, preparing the SQL database for SQL Azure, and configuring authentication. The presentation covers converting the project to a web role, deploying the SQL database to SQL Azure, and options for authentication including SQL Membership, Windows Azure Storage, and Claims-Based Authentication using Access Control Service.

5. A Quick word on Tools

6. Alright, Let’s do this…

7. Windows Azure!!!

8. Windows Azure Compute

9. A Hosted Service is a container for an Application.
An Application must consist of at least one Role.
A Role is Scalable to meet the demand of traffic.

20. public class WebRole : RoleEntryPoint
{ WebRole.cs
// Included in Both Web and Worker Role Template
public override bool OnStart()
{
RoleEnvironment.Changing += RoleEnvironmentChanging;
return base.OnStart();
}
// Included in Worker Role Template - Still available in Web Role but needs to be overridden
public override void Run() { base.Run(); }
// Not Included but available in Web and Worker Roles
public override void OnStop() { base.OnStop(); }
// Is not generated ANYWHERE but SHOULD be Implemented
private static void RoleEnvironmentChanging(object sender, RoleEnvironmentChangingEventArgs e)
{
// If a configuration setting is changing
if (e.Changes.Any(change =>
change is RoleEnvironmentConfigurationSettingChange))
e.Cancel = true; // Set e.Cancel to true to restart this role instance
}
}

21. Prepare your Database
For SQL Azure

Feature Set  XML, Sparse Columns, Filestream
 Partitions
 Full-text indexes
 SQL-CLR

23. Attach NerdDinner Database
1. Open SQL Server Management Studio (SSMS)

4. Click Attach…
5. Find NerdDinner.mdf in App_Data
6. Click OK

24. Generate Scripts for SQL Azure
1. Right-Click Attached NerdDinner Database
2. Click Tasks
3. Click Generate Scripts…
4. Change Database Engine Type to
SQL Azure
5. Click OK
6. Click Finish

25. Connect to SQL Azure
https://<servername>.database.windows.net [SSMS]

26. Create SQL Azure Database
New-SqlAzureServer
-SubscriptionId 1. Sign in to Windows Azure Portal
-Certificate 2. Open SQL Azure Section
-AdministratorLogin 3. Create Server
-AdministratorLoginPassword a) Select Region
-Location b) Create Administration Credentials
c) Add Firewall Rules
4. Create Database

Windows Azure Storage
Membership Approach
<membership defaultProvider="TableStorageMembershipProvider">
<providers>
<clear />
<add name="TableStorageMembershipProvider“

Home Realm Discovery is the act of retrieving a list of the Identity
Providers that are available to your application.
