4. Why the Cloud?“The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.” “By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets”

11. .NET API differencesPermanent storageDo not store data to local disk (ie C:\), but you can use it as a Scratch diskUse the Azure API’s for working with Azure Storage (Blobs/Queues/Tables) or use SQL AzureYou can mount a VHD inside a Blob and mount it as an NTFS drive using Azure Drive to quickly move your application to Azure without rewriting your storage logic.

Sending mail from AzureMail service is not integrated in AzureImplement a SMPT sender queueConnect to a SMPT server to send mail using System.Net.Mail.SmtpClientConnect to a POP3 server to receive mail. Find a working code sample at CodePlexIf you send a lot of mail do not use a free provider, use a commercial provider like SendGrid

16. What is SQL AzureSimilar to an ordinary SQL Server, exposes a tabular data stream (TDS)Familiar SQL Server relational modelUses existing API and tools (SQL2008R2)Friction free provisioning and reduced managementAt the moment, max database size is 50GBComing : SQL Azure Federation Support (spring 2010 )

19. Features and TypesSQL Azure does not support all of the features and data types found in SQL ServerAnalysis Services, Replication, Reporting Services, and Service Broker are not currently provided as services on the SQL Azure.Reporting Services was announced 28. October at the PDC, soon available as a CTP

21. SQL Azure Migration WizardUpgrade your database to SQL2008 firstDownload the Wizard sqlazuremw.codeplex.comRun the Migration WizardAnalyse and fix the reported issues before migratingYou can also script directly from inside SQL Management Studio to SQL AzureTransfer data using BCP – generate CMD script in SQL

22. Top identified problemsAll tables need a clustered indexUNIQUEIDENTIFIER, NEWSEQUENTIALID, DATETIME, ROW GUID COLUMN not supportedUsed for Merge replication, use Sync Framework instead.SELECT INTO is not supportedBoth on physical tables and temp tablesGlobal temp variables not supported##GlobalTmpTableSQL Server Agent not includedThere is no Backup functionalitySync or stream to disk

23. How to optimize for AzureSQL Azure Database Pricing (if app is not CPU bound)$9.99/month for 1 GB increases linearly to $499.95/month for 50 GBThis is the main cost driver for hosted solutions on AzureAzure Storage Pricing (Blobs/Queues/Tables)$0.15/GB stored/monthSuggested actions:Aggregate transactional data that you need to report laterMove data to Azure Table Storage or export to Azure BlobsThe Table service is designed for massive scalability and availability, supporting billions of entities and terabytes of data. It’s designed to support high volume, but smaller structured objects.

24. Reflections on SecurityProtecting yourself

25. Securing the Network, Host and Application – On-premise

26. Securing the Network, Host and Application – In the Cloud

27. Threat Modeling Web ApplicationsStep 1: Identify security objectives. Clear objectives help you to focus the threat modeling activity and determine how much effort to spend on subsequent steps.Step 2: Create an application overview. Itemizing your application's important characteristics and actors helps you to identify relevant threats during step 4.Step 3: Decompose your application. A detailed understanding of the mechanics of your application makes it easier for you to uncover more relevant and more detailed threats.Step 4: Identify threats. Use details from steps 2 and 3 to identify threats relevant to your application scenario and context.Step 5: Identify vulnerabilities. Review the layers of your application to identify weaknesses related to your threats. Use vulnerability categories to help you focus on those areas where mistakes are most often made.

28. Windows Azure Security Notes Tackling cloud security can be overwhelming without an approach. These notes summarize how we took a look at securing Web applications, web services, and data in the cloud. We basically started by mapping out common application scenarios. We then figured out a way to group threats and attacks into a set of common categories. These categories make it easy for us to analyze and inspect the various parts of an application and engineering decisions. Then we focused on finding common principles, patterns, and practices, while working with customers, field, product teams, and industry experts.121 pages

29. Security Best Practices For Developing Windows Azure ApplicationsThis paper focuses on the security challenges and recommended approaches to design and develop more secure applications for Microsoft’s Windows Azure platform. Microsoft Security Engineering Center (MSEC) and Microsoft’s Online Services Security & Compliance (OSSC) team have partnered with the Windows Azure team to build on the same security principles and processes that Microsoft has developed through years of experience managing security risks in traditional development and operating environments.26 pages

30. Patterns & practices Improving Web Services SecurityThis guide shows you how to make the most of WCF (Windows Communication Foundation). With end-to-end application scenarios, it shows you how to design and implement authentication and authorization in WCF. Learn how to improve the security of your WCF services through prescriptive guidance including guidelines, Q&A, practices at a glance, and step-by-step how tos.689 pages

31. Observed Performance

32. Cloud Benefits - Real-world Performance AnalysisFor very limited service requests, Azure-based solution takes slightly longer time to response than self-hosted solution.When more service requests come in, response time of self-hosted solution’s longest transaction will be longer. Meanwhile, response time of Azure-based solution’s longest transaction looks comparatively steady.When service requests increase rapidly, transaction rates of self-hosted solution drops down very fast, meanwhile transaction rates of Azure-based solution looks comparatively better.

33. Performance BenchmarkHardware configuration: Legacy: CPU: 2.4G+2.4G; Memory: 1GB; Hard Drive: 60GBAzure Small Instance: CPU: 1.6GHz; Memory:1.75G; Hard Drive:225G
