  3. 3. What is SQL Azure?In simple terms, moving SQL Server into the cloud. SQL Azure is acloud based relational database & services based on SQL Server technology.SQL Azure offers:• SQL Azure Database (Relational database service)• SQL Azure Reporting (Visualizing data)• SQL Azure Data Sync (bi-directional data synchronizations) © 2012 inZeek All Rights Reserved 3
  4. 4. What is SQL Azure?SQL Azure provides a relational database service called Microsoft SQLAzure Database, a report generation service called Microsoft SQL AzureReporting, a data synchronization service called SQL Azure Data Sync,and a web based database administration and design interface tomanage all above mentioned services in 8 data centers around theworld.

  6. 6. Why SQL Azure Database?This is where SQL Azure comes as database-as-a-service. It is an elasticdatabase platform which provides you the facility to instantly increase ordecrease your database server capacity and most importantly you only pay forwhat you use (pay as you go). And also it does provide you manageability, highavailability, scalability, a familiar development model, and a relational datamodel. Manageability - SQL Azure database offers the scale and functionality of an enterprise data center without the administrative overheads (self-managing capability). High Availability - SQL Azure Database is runs on Windows Server and SQL Server technologies. The SQL Azure service replicates multiple redundant copies of data to multiple physical servers and across world wide data centers to maintain data availability with automatic failover. Scalability - SQL Azure Database natively support scale-out and scale-in data after doing the data partitioning. Simply it performs scale as your data grows. But pay-as- you-grow pricing model allows you only pay for the storage that you use. Familiar SQL Server relational model Using existing APIs & Tools Accessible from Java, PHP, Ruby, etc. Etc. © 2012 inZeek All Rights Reserved 6
  7. 7. SQL Azure Database Editions Web Edition :  Best suited for small Web applications.  Maximum size of 1 or 5 GB of data. Business Edition :  Best suited for independent software vendors (ISVs) or EEnterprise applications.  Database is up to 150 GB of data, in 10GB increments up to 50GB, and then 50 GB increments. Web Edition Select Database Less than Location of data 10GB? center Business Edition © 2012 inZeek All Rights Reserved 7
  8. 8. Variations from SQL Server SQL Azure source database must be based on SQL Server 2008 or higher. Only supports SQL Server Authentication, not the Windows Authentication. SQL Azure does not support heaps. Clustered Index required. Unable to write cross-database reference code. There is no SQL Server Agent in SQL Azure. Unable to access linked servers in SQL Azure. Certain Transact-SQL commands are fully supported; some are partially supported while others are unsupported. Transactional Replication, Log Shipping, Database Mirroring not supported. Accessing SQL Azure over wire is same as SQL server using TDS but SSL is required. Must specific the IP range. SQL Azure has built-in firewall which blocks all external IP’s. © 2012 inZeek All Rights Reserved 8

  10. 10. SQL Azure Reporting Service Microsoft SQL Azure Reporting is a cloud-based reporting service built on SQL Azure and SQL Server Reporting Services technologies and core feature of Windows Azure business intelligence (BI). By using SQL Azure Reporting, you can easily provision and deploy reporting solutions to the cloud. We can use SQL Azure Reporting to add a rich reporting experience to applications running on-premise or in the cloud and most importantly we can author reports using familiar Reporting Services SQL Server tools. And also SQL Azure Reporting Service works the same as SQL Server Reporting Service.*Image courtesy of David Pallmann © 2012 inZeek All Rights Reserved 10

  12. 12. Variations from SQL Server Reporting (SSRS) Creating subscriptions or schedule report snapshots or histories is not supported. Creating SMDL report models is not supported. Creating reports from Report Builder 1.0, Report Builder 2.0, and Report Builder 3.0 is not supported. Report Manager is not available. But SQL Azure Reporting portal provides same features. Use only the SQL Azure data source type. Use only SQL Server Authentication. Report external image is not supported. No extensions are supported in this release. Permissions to reports and report-related items are controlled by role assignment. © 2012 inZeek All Rights Reserved 12
  13. 13. SQL Azure Data SyncSQL Azure Data Sync is a web service (hosted on Microsoft SQL Azure) that youuse to keep your data scheduled bi-directional synchronized (cloud to cloud, onpremises to cloud) across multiple servers in different locations without writinga single line of code. Microsoft SQL Azure Data Sync is built upon the MicrosoftSync Framework.A SQL Azure Data Sync service is ideal for implementing hybrid cloud scenarioand it does allow you to get data where you need it: Sync SQL Azure instances Sync SQL Server to SQL Azure Sync offline apps to SQL Azure Enable geo-replication of data © 2012 inZeek All Rights Reserved 13

  15. 15. SQL Azure Data SyncKey Features : Scale - Service scales as resources requirements grow. No-Code Sync Configuration - Easily define data to be synchronized and locations. Schedule Sync - Choose how often data is synchronized. Conflict Handling - Detect and resolve conflicts caused by the same data being changed in multiple locations. Logging and Monitoring - Administration capabilities for tracking usage. Cleanup Capabilities - Users can clean up their databases if the deprovisioning tasks fail, Deprovisioning tool supports to remove data sync objects, etc.What do I need in order to use SQL Azure Data Sync? Windows Live ID Active Windows Azure Account Active SQL Azure subscription If you are synchronizing with on premises SQL Server database, then must be SQL Server 2005 SP3 or later. © 2012 inZeek All Rights Reserved 15
