Maarten Balliauw gave a presentation on cloud computing and the Windows Azure Services Platform. He began with an overview of cloud computing and defined infrastructure as a service (IAAS), platform as a service (PAAS), and software as a service (SASS). He then discussed Windows Azure and its core services - Blob storage, Table storage, Queue storage, and SQL Azure. Balliauw also covered the Windows Azure AppFabric and its Service Bus and Access Control capabilities. He concluded with information on getting started with Azure and resources for learning more.

- 15. SQL AzureRelational database as a serviceHighly available, automatically maintainedExtension of the SQL Server Data PlatformBusiness AnalyticsReportingData SyncDatabase
- 16. SQL AzureRelational database, provided as a serviceHighly symmetrical development and tooling experience (use TDS protocol and T-SQL)Highly scaled out, on commodity hardwareBuilt on the SQL Server technology foundationBeyond “hosted database”High availability, DB provisioning, and DB management are provided by the servicePay for what you use
- 17. Windows Azure AppFabricSecure connections between servicesAcross organizational boundariesClaims-based access control!= Windows Server AppFabric (yet?)ServiceBusAccessControl
- 18. Windows Azure AppFabric - Service BusSecurely connect applicationsOver the internetAcross any network topologyAcross organizational boundariesPrimary application patternsEventing: Notify applications and/or devicesService Remoting: Securely project on-premises services out to the cloudTunneling: App-to-app communication with NAT/Firewall traversal
- 20. Windows Azure AppFabric - Access ControlProvides outsourcing of claims-based access control for REST web servicesKey capabilities:Usable from any platformLow friction way to onboard new clientsIntegrates with AD FS v2Supports WRAP / SWTEnables simple delegationUsed today by Service Bus and “Dallas”

- 29. Blob StorageStore sets of binary dataText files, images, …Highly AvailableAutomatically scales to multiple servers and locationsDurableData is replicated at least 3 times
- 30. Table StorageStore sets of structured dataNot bound to schema!Billions of entities (rows) and TBs of dataAutomatically scales to thousands of servers as traffic growsHighly AvailableCan always access your dataDurableData is replicated at least 3 times
- 31. Table Storage CapabilitiesWhat tables don’t doWhat tables can doNot relationalNo Referential IntegrityNo JoinsLimited QueriesNo Group byNo AggregationsTransactions (limited)Very ScalableFlexibleDurableStore LOTS of stuff CheapIf these are important to you, use SQL Azure
- 32. Queue ServiceStore a queue of messagesFIFOCan be used by multiple worker roles
- 33. Windows Azure SummaryMany is better than oneLet Microsoft worry about thisLoose couplingWeb Role and Worker RoleStorage choiceAzure Storage: Simple stores scaleTable, Blob, QueueSQL Azure: Full RDBMSStored Procedures, Schema, Transactions, Views etc

- 35. What’s in the cloud?Application Architecture
- 36. ArchitectureQuote: “Some architectures will require rework” All of them will require rework to do it right…Many application architectures not suited for large scale!I can go for multiple web rolesBut not for unlimited web roles…(think performance vs. overhead)Think in “multiple roles”Web rolesBackedbyworkerroleswhereneededArchitecture will be one of the challenges

Editor's Notes
- #29: http://eric.blob.core.windows.net/music/rock/rush/xanadu.mp3Blobs – Provide a simple interface for storing named files along with metadata for the fileTables – Provide structured storage. A Table is a set of entities, which contain a set of propertiesQueues – Provide reliable storage and delivery of messages for an applicationTab
