MSDN - Converting an existing ASP.NET application to Windows Azure

Blob,[object Object], Container,[object Object],Entities,[object Object],Account,[object Object],Table,[object Object],http://<account>.blob.core.windows.net/<container>,[object Object],http://<account>.table.core.windows.net/<table>,[object Object],Messages,[object Object],Queue,[object Object],Windows Azure Storage Concepts,[object Object],http://<account>.queue.core.windows.net/<queue>,[object Object]

Blob Storage,[object Object],Store sets of binary data,[object Object],Text files, images, …,[object Object],Highly Available,[object Object],Automatically scales to multiple servers and locations,[object Object],Durable,[object Object],Data is replicated at least 3 times,[object Object]

Table Storage,[object Object],Store sets of structured data,[object Object],Not bound to schema!,[object Object],Billions of entities (rows) and TBs of data,[object Object],Automatically scales to thousands of servers as traffic grows,[object Object],Highly Available,[object Object],Can always access your data,[object Object],Durable,[object Object],Data is replicated at least 3 times,[object Object]

Table Storage Capabilities,[object Object],What tables don’t do,[object Object],What tables can do,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],,[object Object],Not relational,[object Object],No Referential Integrity,[object Object],No Joins,[object Object],Limited Queries,[object Object],No Group by,[object Object],No Aggregations,[object Object],Transactions (limited),[object Object],Very Scalable,[object Object],Flexible,[object Object],Durable,[object Object],Store LOTS of stuff ,[object Object],Cheap,[object Object],If these are important to you, use SQL Azure,[object Object]

Queue Service,[object Object],Store a queue of messages,[object Object],FIFO,[object Object],Can be used by multiple worker roles,[object Object]

Windows Azure Summary,[object Object],Many is better than one,[object Object],Let Microsoft worry about this,[object Object],Loose coupling,[object Object],Web Role and Worker Role,[object Object],Storage choice,[object Object],Azure Storage: Simple stores scale,[object Object],Table, Blob, Queue,[object Object],SQL Azure: Full RDBMS,[object Object],Stored Procedures, Schema, Transactions, Views etc,[object Object]

Let’s have a look at…,[object Object],an existing application…,[object Object]

Existing ASP.NET application,[object Object],ASP.NET Webforms,[object Object],“Repository pattern”,[object Object],Entity framework,[object Object],Database,[object Object],File storage on server,[object Object],Built with no need for scale,[object Object]

An existing application,[object Object],DEMO,[object Object]

The shortest way to the cloud,[object Object],Migration paths,[object Object]

First things first…,[object Object],Tools:,[object Object],Windows Azure SDK,[object Object],Windows Azure Visual Studio Tools,[object Object],www.microsoft.com/web,[object Object],New solution:,[object Object],Blank “cloud service”,[object Object],Add existing projects,[object Object],Promote to “web role”,[object Object]

Migration paths: hosting & file storage,[object Object],Windows Azure Web Role,[object Object],Hosting the web application,[object Object],Windows Azure Blob Storage,[object Object],Hosting “user uploaded content”,[object Object],Option 1: HttpHandler,[object Object],+ Abstraction and migration freedom,[object Object],- Traffic & related costs,[object Object],Option 2: public blob container + Azure CDN,[object Object],+ Traffic & related costs+ Pretty download URL,[object Object],+ Fast! Nearby!,[object Object],- Abstraction and migration freedom,[object Object]

Migration paths: data,[object Object],Option 1: SQL Azure,[object Object],Easiest migration path for data,[object Object],More powerful RDBMS,[object Object],Sync Framework Power Pack: http://bit.ly/5hTtSY,[object Object],SQL Azure Migration Wizard: http://sqlazuremw.codeplex.com/,[object Object],Option 2: Table storage,[object Object],Will be cheaper in operating costs for small applications,[object Object],Will probably require some rework,[object Object]

Migrating the application,[object Object],DEMO,[object Object]

Think before you go cloudy…,[object Object],Considerations,[object Object]

Hosting,[object Object],Migration,[object Object],Will be an easy migration,[object Object],Remember to use the providers from the SDK,[object Object],Keep the “multiple roles” idea in mind!,[object Object],Considerations to make,[object Object],Store all content in the application?,[object Object],Requires a re-deployment quite often…,[object Object],Better: store more dynamic content on blob storage,[object Object],Background processing,[object Object],Try moving heavy CPU tasks to worker role where appropriate,[object Object],One web role?,[object Object],Will be cheaper…,[object Object],But will have your application down during upgrade…,[object Object],Better: always > 1 web role (at least 2),[object Object]

Database,[object Object],Working with EF / NHibernate / (insert ORM here)?,[object Object],SQL Azure wil be easiest path, but is more expensive,[object Object],Table storage…,[object Object],Will get you frustrated if your application design is bad!(like mine in the demo),[object Object],Use simple data structures for table storage,[object Object],Map these to whatever you want in your application,[object Object]

Architecture,[object Object],Quote: “Some architectures will require rework” All of them will require rework to do it right…,[object Object],Current application architecture not suited for large scale!,[object Object],I can go for multiple web roles,[object Object],But not for unlimited web roles…,[object Object],Think in “multiple roles”,[object Object],Web roles,[object Object],Backedbyworkerroleswhereneeded,[object Object],Architecture will be one of the challenges,[object Object]

Typical Architecture,[object Object],Service Unavailable,[object Object],VIP,[object Object],Worker Role,[object Object],Web Role,[object Object],Windows Azure Storage ,[object Object],(Blob, Table, Queue),[object Object]

Web + Worker Role Service Model,[object Object],Worker Role,[object Object],Service Still Available,[object Object],Worker Role,[object Object],Web Role,[object Object],VIP,[object Object],Worker Role,[object Object],Web Role,[object Object],Worker Role,[object Object],Worker Role,[object Object],Windows Azure Storage ,[object Object],(Blob, Table, Queue),[object Object]

Windows Azure - Coming soon…,[object Object],Programming model,[object Object],Administrator privileges in the VM,[object Object],Deployment of pre-configured VM images,[object Object],Still obtain the benefits of the WA service model,[object Object],Storage,[object Object],User-selectable geo-locations for replicas,[object Object],Secondary indices on tables,[object Object],Service management,[object Object],Remote terminal server access to VMs,[object Object]
