.NET Usergroup Oldenburg 26. März 2015 - von Winfried Klinker und Andre Hühn Microsoft Azure gehört zu den Cloud-Diensten, die Microsoft anbietet. Es umfasst neben dem Hosting von virtuellen Maschinen insbesondere eine große Sammlung an Diensten (wie SQL Azure, Mobile Services, Machine Learning). Wir geben einen ersten Überblick über die Features von Azure insbesondere für Entwickler. Dabei werden wir sowohl auf die Platform as a Service (PaaS) Angebote wie auch auf die Infrastructe as a Service (IaaS) eingehen. Außerdem geben wir einen Einblick in moderne Cloud Architektur und zeigen Best Practices bei der Cloud Entwicklung auf. Dabei werden Beispiele aus der Praxis zeigen, wie man eine Fehlertolerante und robuste Cloud Lösung erstellen kann. Über die Sprecher: Winfried Klinker ist als Software Architekt bei der Firma Sitrion in Oldenburg tätig. Er beschäftigt sich größtenteils mit Cloud Architekturen mit Microsoft Azure vor allem in Bezug auf Backends für mobile Anwendungen. Andre Hühn ist Team Lead für Entwicklung mobiler Apps bei der Firma Sitrion in Oldenburg und beeinflusst damit die Richtung der Architektur für das Sitrion ONE Produkt.

25. Cloud
Development-
Patterns

26. General Things to consider
• Design everything to be Stateless (if possible)
• use PaaS over IaaS
• use Async
• Automate everything
• Right tool for the job
• SQL
• TableStorage
• BlobStorage
• NoSQL (DocumentDB, MongoDB, Cassandra)

27. Data Storage Options

28. Data partion strategies
Vertical Partitioning

29. Data partion strategies
Horizontal Partitioning
Azure TableStorage does this automatically based on the PartionKey

30. Data partion strategies
Hybrid Partitioning

31. Dev Ops
• Continous Integration & Deployment
• Works on my machine!
• Monitoring
• Telemetry (User behavior and usage)
• VisualStudio Online is free for up to 5 users, automatic
deployment from SourceControl to Azure

32. Design for failure
• Everything can fail at any time
• Transient Faults (self healing)
• Network issues
• Timeouts
• Use Traffic Manager route traffic to differnt data centers
• Use AutoScale to handle peak times

33. Transient Fault Handling
•Entity Framework supports Retry Policy since 6.0
•Azure SDKs include Retry Policies
•Create custom HttpHandler for calling external
services
public class MyConfiguration : DbConfiguration
{
public MyConfiguration()
{
SetExecutionStrategy(
"System.Data.SqlClient",
() => new SqlAzureExecutionStrategy(1, TimeSpan.FromSeconds(30)));
}
}
IRetryPolicy linearRetryPolicy = new LinearRetry(TimeSpan.FromSeconds(2), 10);
blobClient.RetryPolicy = linearRetryPolicy;

34. HttpClient Handler
protected override async Task<HttpResponseMessage> SendAsync( HttpRequestMessage request, CancellationToken
cancellationToken) {
HttpResponseMessage response = null;
for (int i = 0; i < _maxRetries; i++)
{
response = await base.SendAsync(request, cancellationToken);
if (response.IsSuccessStatusCode)
{
return response;
}
if (response.StatusCode == HttpStatusCode.Unauthorized)
{
var token = await _connector.GetRefreshToken();
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token.accessToken);
}
if (response.StatusCode == HttpStatusCode.NotFound)
{
return response; //No neet to retry 404
}
if (response.StatusCode == (HttpStatusCode) 429)
{
//Too many requests, back off
Thread.Sleep(2000);
}
}
return response;
}
34
VAR CLIENT = NEW HTTPCLIENT(NEW RETRYWITHAUTHHANDLER<EXACTCONNECTOR>(NEW HTTPCLIENTHANDLER(), 3, THIS));

35. Queue centric work pattern
• Decouple tiers
• Allows to scale efficiently
• Handle unexpected peak loads
• Works great with AutoScale
• Use for all non interactive scenarios
• Examples:
• Send Emails
• Create Thumbnails of uploaded pictures
• Write results to storage

36. Microservices
• Each MicroService is part of an application (no SOA)
• Autonom
• Fast development and integration
• Allows for experiments
• Best language for the job

37. SingleSignOn (SSO)
• Azure Active Directory
• Support SAML, WS-Fed and
Oauth
• Link to On Premise
Directory
• Connect with ADFS On
Premise

38. Azure @ Sitrion
• Websites
• Cloud Services
• SQL Database
• DocumentDB
• Storage
• Traffic Manager
• Redis Cache
• ServiceBus
