9. Architecture differences
What is the same:
- ASP.NET application runs on IIS and Windows Server
- Application uses SQL server Development is still done with VS
Main differences:
- Application consists of parts called roles
- There is no persistent/durable virtual machine
- There is no persistent/durable NTFS file system
- Application runs in multi instance (server) environment
- New API, new configuration files, new type of project

11. Windows Azure Roles
• Web Role
– for web application programming in ASP.NET or PHP
– MVC 3
• Worker Role
– for performing work on behalf of the web role
– may be written in .NET, Ruby, Java
– to improve scalability by increasing parall. and async.
– used for background work

13. Developer Experience
• Leverage Existing Skills in .NET, SQL Server, WCF
• Use Familiar tools – Visual Studio
• RESTful HTTP cloud services, supports PHP, Python
• Cloud apps can be developed locally / offline
• SDK Cloud Simulator – Dev Fabric, Dev Storage

16. Storage
• Blobs – Large Data Store
• Queues – Background work processing
• Tables – Very Fast / Scalable Storage
• Drives – NTFS Formatted Page Blobs
• SQL Azure – Relational SQL in the Cloud

your CV «NoSQL» (Joke)

19. Mongo DB
Running MongoDb on Microsoft Windows Azure with CloudDrive
• http://www.captaincodeman.com/2010/05/24/mongodb-azure-
clouddrive/
Server :
_mongoProcess = new Process(@"mongod.exe");
_mongoProcess.Start();
Client:
var mongo = new Mongo(connectionString);
mongo.Connect();
var db = mongo.GetDatabase("notes");

20. Alternative for Azure Queue
• RabbitMQ (erlang)
• Service Bus Queues (app fabric)

21. Building a Task Scheduler in
Windows Azure
Windows Azure: technology cocktail 21

22. Scheduling
public class ScheduledItem : TableServiceEntity
{
public string Message { get; set; }
public DateTime Time { get; set; }
public ScheduledItem(string message, DateTime time)
: base(string.Empty, time.Ticks.ToString("d19") + "_" + Guid.NewGuid().ToString())
{
Message = message;
Time = time;
}
public ScheduledItem()
{
}
}

23. Managing Concurrency
using (var arl = new AutoRenewLease(leaseBlob))
{
if (arl.HasLease)
{
// inside here, this instance has exclusive access
var ctx = tables.GetDataServiceContext();
foreach (var item in ctx.CreateQuery<ScheduledItem>("ScheduledItems").Where(s =>
s.PartitionKey == string.Empty
&& s.RowKey.CompareTo(DateTime.UtcNow.Ticks.ToString("d19")) <= 0)
.AsTableServiceQuery())
{
q.AddMessage(new CloudQueueMessage(item.Message));
ctx.DeleteObject(item);
ctx.SaveChangesWithRetries();
}
}
}
