Windows Azure: technology cocktail

“ !Поехали ”

Azure

• Windows Azure Platform is thus classified as platform as a service and forms part of Microsoft's cloud computing strategy, along with their software as a service offering, Microsoft Online Services

What is Windows Azure

• Cloud computing service from Microsoft• Combination of PaaS and IaaS• New development platform


• 1 2

Architecture differences

What is the same: - ASP.NET application runs on IIS and Windows Server- Application uses SQL server Development is still done with VSMain 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

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

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

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


If you don’t know SQL – write in your CV «NoSQL» (Joke)


Azure Storage Problems


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");

Alternative for Azure Queue

• RabbitMQ (erlang)• Service Bus Queues (app fabric)


Building a Task Scheduler in Windows Azure


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() {}

}


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(); } }}


Alternative Schedule

• Quartz• BrokeredMessage.ScheduledEnqueueTime


Node.js Applications

1. native Windows Node.js binaries 2. iisnode module
