Starting with the Basics

Start With the BasicsSQL Azure Database isSQL Server database technology delivered as a service on the Windows Azure PlatformIdeal for both simple and complex applicationsEnterprise-ready with automatic support for HADesigned to scale out elastically with demand

Get started quicklyChoose a planChoose a billing optionProvision servers

Ready to get started?Let’s jump into development

Provision Your ServerServer definedService head that contains databasesConnect via automatically generated FQDN (xxx.database.windows.net)Initially contains only a master database

Provision servers interactivelyLog on to Windows Azure Management PortalCreate a SQL Azure serverSpecify admin login credentialsAdd firewall rules and enable service access

Build and Deploy your Database

Build Your DatabaseUse familiar technologiesSupports Transact-SQLSupports popular languages

.NET Framework (C#, Visual Basic, F#) via ADO.NETC / C++ via ODBCJava via Microsoft JDBC providerPHP via Microsoft PHP provider

Supports popular frameworksOData, Entity Framework, WCF Data Services, NHibernate

Supports popular toolsSQL Server Management Studio (2008 R2 and later)SQL Server command-line utilities (SQLCMD, BCP)CA Erwin® Data ModelerEmbarcadero Technologies DBArtisan®

Differences in comparison to SQL Server Focus on logical vs. physical administrationDatabase and log files automatically placedThree high-availability replicas maintained for every databaseDatabases are fully containedTables require a clustered indexMaximum database size is 50 Gb

Unsupported SQL Server featuresBACKUP / RESTOREUSE command, linked servers, distributed transactions, distributed views, distributed queries, four-part namesService BrokerCommon Language Runtime (CLR)SQL Agent

Build Your DatabaseThin client database developmentIntroducing the SQL Azure management portalWeb designers for tables, views, stored procsInteractive query editing and execution

Rich client database developmentIntroducing SQL Server Data Tools (SSDT)Visual Studio IDE for database developmentIncludes modern designers and projects with declarative, model-driven developmentDevelop and test in both connected and disconnected statesPlatform targeting for both SQL Server (2005 and above) and SQL AzureGet it free with Web PI, with SQL Server 2012 and with Visual Studio 11

Deploy Your DatabaseData-tier Application Framework (DAC Fx)Alternative to traditional script based approachDramatically simplifies deployment, migration and versioning of databasesProvides a single unit of deployment for schema (dacpac) or for schema + data (bacpac)Supports automatic versioning of database schemasSupports platform targeting for both SQL Server (2005 and above)

and SQL AzureBuild from scratch or extract from existing db

Secure your Database

There are two ways to secure a database:

Within the Database

On the Server

BenefitsServer identity and access controlSQL authentication supported Integrated authentication not supportedConnect to master to administer logins and create / drop databasesThe admin login (configured during service provisioning) is like saThe admin login has full rights on the server (and all databases) and should only be used for administrationManage logins with CREATE / ALTER / DROP LOGIN commandsMembership in the loginmanager server role grants CREATE / ALTER / DROP LOGIN privilegesMembership in the dbmanager server role grants CREATE / DROP DATABASE privileges

BenefitsDatabase identity and access controlLogins must have an associated user account to connect to a databaseThe admin login is automatically associated with a special user known as dbo (database owner)The dbo has full rights in the database and should only be used for administrationManage users with CREATE / ALTER / DROP USER commandsAdd users to system or user-defined database roles to grant privileges via sp_add_rolememberOrganize database objects into schema containers based upon common access control requirementsGrant privileges to schema containers instead of individual objects for better productivity

Connect Your ApplicationConnecting to SQL Azure1. TDS (Tabular Data Stream) protocol over TCP/IP

supported2. SSL required3. Use firewall rules to connect from outside Microsoft

data centerASP.NET EXAMPLE:

Special considerations1. Legacy tools and providers may require special

format for login: [login]@[server]2. Idle connections terminated after 30 minutes3. Long running transactions terminated after 24 hours4. DoS guard terminates suspect connections with no

error message5. Failover events terminate connections6. Throttling may cause errors7. Use connection pooling and implement retry logic to

handle transient failures8. Latency introduced for updates due to HA replicas9. No cross-database dependencies, result sets from

different databases must be combined in application tier

<connectionStrings><addname="AdventureWorks"connectionString=

"Data Source=[server].database.windows.net;Integrated Security=False;Initial Catalog=ProductsDb;User Id=[login];Password=[password];Encrypt=true;"

SQL Azure Data Sync isMicrosoft Sync Framework technology delivered as a service on the Windows Azure PlatformIdeal for scheduling synchronization between data sets hosted in SQL Azure or SQL ServerUses a hub and spoke topology

Special considerationsConflict resolution policy configured centrally (hub or client wins)Sync direction configured between each client and the hub (to hub, from hub, bi-directional)Sync schedule must be between 5 minutes and 1 monthData sets include multiple tables and can be filtered, triggers are added to data set tables Tables added to hub and client schemasAgent must be installed for on-prem clients

Synchronize Your DataProvisioning synchronization groupsDeploy database to hub and clientsSet synchronization scheduleSet conflict resolution policyDefine data setAdd SQL Azure clients to topologyInstall agents on SQL Server clients and add them to topology using keysDeploy topology

Operational considerationsManual synchronization supportedHub updates require one synchronization to distribute to all clientsClient updates require two synchronizations to distribute to all clientsSync Framework triggers may affect application behavior

Scale Out Your DataSQL Azure Federations providesIntegrated database sharding that can scale to hundreds of nodesMulti-tenancy via flexible repartitioningOnline split operations to minimize downtimeAutomatic data discovery regardless of changes in how data is partitioned

Special considerationsA logical database can contain multiple federationsDistribution scheme supports int, bigint, guid, and varbinary typesFiltering routes connection to appropriate shard regardless of changes in partitionsMerge, fan-out queries and automatic distribution of schema changes not supported in initial release
