Training Workshop Windows Azure Platform

Presentation Outline (hidden slide): Technical Level: 200 Intended Audience: Developers Objectives (what do you want the audience to take away): Understand the basic concepts of building SQL Azure apps Presentation Outline (including demos): SQL Azure Overview Setting Up a SQL Azure Account Connecting to SQL Azure Managing Logins and Security Creating Objects Migrating Database Schemas Moving Data Special Considerations Building a Simple App

3 Building Applications using SQL Azure Name Title Organization

Business Analytics Reporting 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 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” MS Datacenter MS Datacenter Windows Azure Compute Windows Azure Compute Browser SOAP/REST HTTP/S T-SQL (TDS) App Code (ASP.NET) SQL Server Report Server (on-premises) ADO.NET/REST - EDM HTTP/S - AD Federation (LiveId /AppFabric AC) SQL Azure Database SQL Azure Database T-SQL (TDS) Relational database service SQL Server technology foundation Highly symmetrical Highly scaled Highly secure Database “as a Service” – beyond hosting Highly scaled out relational database as a service

6 SQL Azure Network Topology Application Load Balancer TDS (tcp:1433) Applications use standard SQL client libraries: ODBC, ADO.Net, … Load balancer forwards ‘sticky’ sessions to TDS protocol tier Data Node Gateway Scalability and Availability: Fabric, Failover, Replication and Load balancing

7 Performance Considerations The distance your application travels to perform data access will affect performance

8 V1 Application Topologies MS Datacenter SOAP/REST HTTP/S SQL Azure access from within MS Datacenter (Azure compute – ADO.NET) Windows Azure T-SQL (TDS) MS Datacenter T-SQL (TDS) App Code / Tools SQL Azure access from outside MS Datacenter (On-premises – ADO.NET) App Code (ASP.NET) ADO.NET Data Svcs/REST - EF HTTP/S Code Far SQL Data Services Application/ Browser Code Near

10 Service Provisioning Model Each account has zero or more servers Azure wide, provisioned in a common portal Billing instrument Each server has one or more databases Contains metadata about the databases and usage Unit of authentication Unit of Geo-location Generated DNS based name Each database has standard SQL objects Unit of consistency Unit of multi-tenancy Contains Users, Tables, Views, Indices, etc. Most granular unit of billing Account Account Server Server Database Database

11 Setting Up SQL Azure Account Request token for SQL Azure at Tokens will generally be provisioned within a couple days Redeeming tokens Setup administrative user Specify geo-location

12 Preparing your SQL Azure Account (click-through & portal)

13 SQL Azure Deployment SQL Azure TDS Gateway SQL Azure TDS Gateway DB Script

14 SQL Azure Accessing databases Your App Change Connection String SQL Azure TDS Gateway SQL Azure TDS Gateway

15 Connecting to SQL Azure Connect via ADO.NET, ODBC, etc. OLE DB is NOT supported May need to 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

16 Connecting to SQL Azure

17 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

18 Managing Logins & Security in SQL Azure

19 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 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

20 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 SQL Server configuration options SQL Server Service Broker System tables Trace Flags

21 Creating Objects in SQL Azure

22 Migrating Databases “Just change the connection string” * o nce 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

23 Migrating Database Schemas to SQL Azure

24 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

25 Moving Data into SQL Azure with SSIS

26 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

27 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

28 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
