Building Applications with SQL Azure and Windows Azure Session Agenda Introduction to SQL Azure SQL Azure Architecture SQL Azure Application Architectures Scaling out with SQL Azure

(Re) Introducing: SQL Azure Database What SQL Azure is… A massively scaled, multi-tenant relational database service built on commodity hardware A symmetric extension to a uniquely powerful data platform What it isn’t… Database hosting Done What a long, strange trip it’s been…

Extending SQL Data Platform to Cloud Relational Database service (Windows Azure Platform) Key differentiator for SQL Server platform High-Level Features Self-provisioning and capacity on demand Automatic high-availability Automated management (infrastructure) Symmetry with on-premises platform Simple, flexible pricing model – pay for what you use New, differentiated capabilities… Web & Departmental Applications SaaS ISVs (SMB) Enterprise SIs & Internal MS Properties SQL Azure Browser MS Datacenter SOAP/REST HTTP/S SQL Azure (Windows Azure Compute) Windows Azure Compute T-SQL (TDS) App Code (ASP.NET) SQL Server Report Server (on-premises) Astoria/REST - EDM HTTP/S SQL Azure T-SQL (TDS)

SQL Azure Recap SQL Azure provides capacity on demand Create new server Create new database within existing server Server lifecycle controlled via Portal Portal login using LiveID Database lifecycle via TSQL Auth using ‘SQL login’ over TDS+SSL

Compatibility Goals Support common application patterns Logical/policy based administration Patterns work for SQL Azure and SQL Server Multi-tenancy considerations Throttling and load balancing Limits on DB size, duration of transaction, etc V1: Address the needs of 95% or more web and departmental application

Sample of SQL Compatibility Included in v1 Tables, indexes and views Stored Procedures Triggers Constraints Table variables, session temp tables (#t) … Out of Scope for v1 Distributed Transactions Distributed Query CLR Service Broker Spatial Physical server or catalog DDL and views

A lap around SQL Azure

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

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

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

Code Far Applications Data is typically located outside the firewall from where your application runs Design your application to handle latency Pre-fetch as much data as possible to provide a rich experience to your users Cache data locally

Code Near Architecture Application Code runs within the same network that your data resides on Windows Azure provides a scalable hosting and compute platform for hosting your applications SQL Azure and Windows Azure provide a “better together” experience

Code Near vs Code Far

Why scale your application Increase an application’s ability to process and store data Usually because of heavy resource consumption Increased workloads Increased CPU / IO requirements Increased storage requirements

Scale Out Patterns Multiple ‘standard’ scale out patterns Range – break range into chunks Ranges can be variable in size Good for range based queries Can suffer from hotspots depending on workload Hashing – apply hash to application workload Good for distributing values Poor for range queries (needs full fan-out)
