Windows Azure Platform
Compute:Virtualized compute environment based on Windows Server
Storage: Durable, scalable, & available storage
Management: Automated, model-driven management of the service
Database:Relational processing for structured/unstructured data
Service Bus: General purpose application bus
Access Control: Rules-driven, claims-based access control

Extending SQL Data Platform to Cloud
Reference Data
Business Intelligence
Data Sync
Reporting
SQL Azure Database
Symmetric Programming Model
Data Hub Aggregation
Initial Services
Database – Core SQL Server database capabilities
Future Services
Data Sync – Enables the sync framework (soon after PDC)
Additional SQL Server capabilities available as a service: Business Intelligence and Reporting
New services: Reference Data and Secure Data Hub

Microsoft SQL Azure
Clear Feedback: “I want a database in the Cloud”
Familiar SQL Server relational model
Uses existing APIs & tools
Friction free provisioning and reduced management
Built for the Cloud with availability and scale
Accessible to all from PHP, Ruby, and Java
Focus on combining the best features of SQL Server running at scale with low friction

SQL Azure V1 targets scenarios that live in the lower left quadrant

Scenarios for V1
Departmental Applications
Simple application built by individual or department
Need simple deployment, self-management, IT: “Empowerment and Governance”
Web Applications
Small business or startup that uses the cloud as their IT
Simple deployment, self-management, scale on demand
ISV
ISV hosting software on behalf of customer
Multi-tenant support for billing and isolation
Data Hub (Shortly After V1)
Sharing and aggregating of data across tiers and across enterprises
Centralized place for data, high scale, sync with existing data sources

V1 Application Topologies

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

Architecture
Shared infrastructure at SQL database and below
Request routing, security and isolation
Scalable HA technology provides the glue
Automatic replication and failover
Provisioning, metering and billing infrastructure

Programming Model
Small Data Sets
Use a single database
Same model as on premise SQL Server
Large Data Sets and/or Massive Throughput
Partition data across many databases
Use parallel fan-out queries to fetch the data
Application code must be partition aware in v1
For v1 will publish best practices for scale out
Post-v1 we are looking at building an abstraction to hide some of the complexities of partitioning

Sharding Databases
1 x 10GB database
1 Instances
10 x 1GB databases
10 Instances

SQL Tooling & Development
Demo

Managing your account

Viewing database information

Sample screen – requires VS2010

Compatibility Goals
Support common application patterns
Logical/policy based administration
Patterns work from SQL Server to SQL Azure
Multi-tenancy considerations
Throttling and load balancing
Limits on DB size, transaction duration, …
V1: Address the needs of the majority of web and departmental application

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

Connection Model
Use existing client libraries
ADO.NET, ODBC, PHP
Client libraries pre-installed in Azure roles
Support for ASP.NET controls
Clients connect directly to a database
Cannot hop across DBs (no USE)

Logical vs. Physical Administration
SQL Azure focus on logical administration
Schema creation and management
Query optimization
Security management (Logins, Users, Roles)
Service handles physical management
Automatically replicated with HA “out of box”
Transparent failover in case of failure
Load balancing of data to ensure SLA
DBA role places more focus on logical management

Deployment
Support for basic deployment options
SQL scripts work (but not attach database)
Geo-location of Windows Azure compute and SQL Azure Databases
Support for Application and multi-server management model
Support for application packages
Cloud or on-premise is a deployment time choice
Visibility of data across on-premise and the cloud
Support existing and new forms of deployment

Security Model
Uses regular SQL security model
Authenticate logins, map to users and roles
Authorize users and roles to SQL objects
Limited to standard SQL Auth logins
Username + password
Future AD Federation, WLID, etc as alternate authentication protocols
Security model is 100% compatible with on-premise SQL

Platform Readiness (EHA)
Exchange Hosted Archive (EHA) is high scale archival service
Runs on SQL Azure infrastructure
In production prior to SQL Azure v1
Rebuilt to address cost and scale issueshttp://www.microsoft.com/casestudies/Case_Study_Detail.aspx?CaseStudyID=4000003098
Reduced COGS with increased customerand business benefit:
Larger scale (e.g. larger customers ~20TB+ each)
More self-managing (e.g. fault-tolerance)
Better query performance for fan-out
Faster provisioning of new customers

SQL AzureOpportunities and Futures
Partitioned databases
Geo-location and geo-redundancy
Distributed query
Security w/AD, WLID, etc
Support for multiple levels of hardware and software isolation
