Windows Azure Platform Training Workshop Building Applications using SQL Azure Name Title Organization Email 3 Reporting Business Analytics Data Sync The Power of the SQL Data Platform in the cloud Leverages existing skills and rich tooling ecosystem Enables database applications with new, “cloud” capabilities SQL Azure Database Highly scaled out relational database as a service Relational database service Browser • SQL Server technology foundation SOAP/REST HTTP/S • Highly symmetrical ADO.NET/REST - EDM HTTP/S • Highly scaled • Highly secure App Code (ASP.NET) Windows Azure Compute T-SQL (TDS) SQL Azure Database SQL Server Report Server (on-premises) T-SQL (TDS) MS Datacenter - AD Federation (LiveId /AppFabric AC) Database “as a Service” – beyond hosting Customer Value Props Self-provisioning and capacity on demand Symmetry w/ on-premises database platform Automatic high-availability and fault-tolerance Automated DB maintenance (infrastructure) Simple, flexible pricing – “pay as you grow” SQL Azure Network Topology Application Applications use standard SQL client libraries: ODBC, ADO.Net, … TDS (tcp:1433) Load Balancer Load balancer forwards ‘sticky’ sessions to TDS protocol tier TDS (tcp: 1433) Gateway Gateway Gateway Gateway Gateway Gateway TDS (tcp: 1433) Data Node Data Node Data Node Data Node Data Node Data Node Scalability and Availability: Fabric, Failover, Replication and Load balancing 6 Performance Considerations The distance your application travels to perform data access will affect performance 7 V1 Application Topologies SQL Azure access from within MS Datacenter SQL Azure access from outside MS Datacenter (Azure compute – ADO.NET) (On-premises – ADO.NET) Application/ Browser SOAP/REST HTTP/S App Code / Tools ADO.NET Data Svcs/REST - EF HTTP/S App Code (ASP.NET) Windows Azure T-SQL (TDS) T-SQL (TDS) SQL Data Services MS Datacenter Code Near 8 SQL Data Services MS Datacenter Code Far Data Hub “An aggregation of Enterprise, Partner, Desktop, and Device data within SQL Azure” Windows Azure Enterprise On-premises App Azure App SQL Azure Enterprise User Management Device Management Business Logic / Rules 9 Device Desktop Sync Gateway Client App Client App Sync Client Sync Client Service Provisioning Model Each account has zero or more servers Account Azure wide, provisioned in a common portal Billing instrument Each server has one or more databases Server Contains metadata about the databases and usage Unit of authentication Unit of Geo-location Generated DNS based name Each database has standard SQL objects Database 10 Unit of consistency Unit of multi-tenancy Contains Users, Tables, Views, Indices, etc. Most granular unit of billing Setting Up SQL Azure Account Request token for SQL Azure at http://www.azure.com/ Tokens will generally be provisioned within a couple days Redeeming tokens Setup administrative user Specify geo-location 11 Preparing your SQL Azure Account (click-through & portal) 12 SQL Azure Deployment DB Script 13 SQL Azure TDS Gateway SQL Azure Accessing databases Change Connection String Your App 14 SQL Azure TDS Gateway Connecting to SQL Azure Connect via ADO.NET, ODBC, etc. OLE DB is NOT supported May need to include <login>@<server> USE statement is NOT currently supported Use familiar tools (sqlcmd, osql, SSMS, etc) Current version of SSMS is not fully supported but it works (demo to come) Tools will evolve before PDC for increased support 15 Connecting to SQL Azure 16 SQL Azure Security Supports SQL Server Security On-premise SQL Server security concepts still apply Server-level: sds_dbcreator, sds_securityadmin roles Database-level: same as on-premise SQL Server SSMS Object Explorer is NOT currently supported Administrative user is equivalent to sa 17 Managing Logins & Security in SQL Azure 18 T-SQL Support (full or partial) Constants Constraints Cursors Index management and rebuilding indexes Local temporary tables Reserved keywords Stored procedures Statistics management Transactions Triggers 19 Tables, joins, and table variables Transact-SQL language elements such as Create/drop databases Create/alter/drop tables Create/alter/drop users and logins … User-defined functions Views T-SQL Not Supported (v1) Common Language Runtime (CLR) Database file placement Database mirroring Distributed queries Distributed transactions Filegroup management Full Text Search Global temporary tables Spatial data and indexes 20 SQL Server configuration options SQL Server Service Broker System tables Trace Flags Creating Objects in SQL Azure 21 Migrating Databases “Just change the connection string” * once database is migrated Generate script wizard from SSMS currently creates unsupported DDL SQL Server Management Studio 2008 R2 has increased support for SQL Azure Migrating Databases to SQL Azure HOL in the Windows Azure Platform Training Kit 22 Migrating Database Schemas to SQL Azure 23 Moving data Scripted INSERT statements SQL Server Integration Services Available in Developer and Trial editions Use ADO.NET endpoint BCP (bulk copy) is supported DataSync will enable Microsoft Sync Framework 24 Moving Data into SQL Azure with SSIS 25 Special Considerations: Database Size Maximum single database size is currently 10GB Database size calculation Includes: primary replica data, objects and indexes Does NOT include: logs, master database, system tables, server catalogs or additional replicas V1 does not support auto-partitioning or fan-out queries Must handle partitioning logic within the application See scale out SQL Azure content within the Windows Azure Platform Training Kit for additional guidance 26 Special Considerations: Throttling MSDN • Use traditional SQL Server best practices • CTP cluster has throttling limits turned up to allow for building logic into apps for handling this case • Build in retry logic especially if you expect very high throughput demands • Consider scaling out for high throughput scenarios 27 Special Considerations: PHP SQL Azure does NOT support Multiple Active Result Sets (MARS) Must use the SQL Server for PHP v1.1 or newer with MARS connection option set to FALSE 28 Building a Windows Azure App Connected to SQL Azure 29 Learning SQL Azure www.azure.com Hands on Labs in Windows Azure Platform Training Kit Follow the team bloggers 30 Want to Know More?
