Roll-your-own HA/DR/scale
SQL Azure V1 targets scenarios that live in the lower left quadrant
9
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

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
19
Sharding Databases
• 1 x 10GB database ‒ 1 Instances
• 10 x 1GB databases ‒ 10 Instances
21
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
22
Sample of SQL Compatibility
In Scope for 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
23
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)
24
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
25
Deployment
Support existing and new forms of 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
26
Security Model
• Uses regular SQL security model ‒ Authenticate logins, map to users and roles
‒ Authorize users and roles to SQL objects
• Support for standard SQL Auth logins ‒ Username + password
• Future AD Federation, WLID, etc as alternate authentication protocols
Security model is 100% compatible with on-premise SQL
27
Pricing
Web Edition
• 1 GB Database
• $9.99 / month
• Bandwidth ‒$0.10 /GB inbound
‒$0.15 /GB outbound
Business Edition
• 10GB Database
• $99.99 / month
• Bandwidth ‒$0.10 /GB inbound
‒$0.15 /GB outbound
• Specified by MAXSIZE on CREATE DATABASE command or portal
• Billing granularity is the day
• Monthly billing period
28
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 issues http://www.microsoft.com/casestudies/Case_Study_Detail.aspx?CaseStudyID=4000003098
Reduced COGS with increased customer and 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
29
SQL Azure Opportunities 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
