SDS V1 targets scenarios that live in the lower left quadrant

SDS Concepts
Provisioning model
Account, server, database
Traditional SQL security model
Authenticate logins, map to users and roles
Authorize users and roles to SQL objects
Familiar SQL programming model
Traditional SQL Server relational model
Support ADO.Net, ODBC
Applications must be partition aware for larger databases

Extending SQL Data Platform to Cloud
Reference Data
Business Intelligence
Data Sync
Reporting
SQL Data Services (SDS)
Database-as-a-Service
Symmetric Programming Model
Data Hub Aggregation
Initial services – core RDBMS capabilities as a service (SDS), Data Sync and Data Hub
Future Offerings
Additional data platform capabilities as a service: BI/DSS, DW
New services: Reference Data, Secure Data Hub
Enable new uses of data to deliver differentiated business value

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
Unit of authentication
Unit of Geo-location
Each database has standard SQL objects
Unit of consistency
Contains users, tables, views, indices, etc…
Account
Server
Database

SDS Server and Database Provisioning

Architecture
Shared SQL infrastructure
Each user database is replicated to multiple servers
Client requests are routed to current “primary database”
State-of-the-art HA technology
Automatic failure detection; client request re-routed to new primary
Load balancing across shared resource pool
Gateway provides TDS entry point, provisioning capability

Data Hub – Project “Huron”
Customer Segment
Small and medium sized businesses
Enterprise – rapid prototype
Both Microsoft (v1) and Non-Microsoft device (post v1)
Common Patterns
Mobile device access to corporate data
Business to business sharing
Secure digital data hub / partner extranets
Governmental data (searchable encryption)

Scalability and Availability: Fabric, Failover, Replication and Load balancing

Scaling Out With SQL Data Services
How can I gain maximum performance from my data tier?
What if my application has large data storage requirements?
Scaling out with SQL Data Services addresses these requirements

An Example Scale Out Architecture
ASP.Net
Application
Customer 123
Partition
Aware
App Tier
Data
Partitions
“Shards”

Software Installation and Patching
SDS Responsibilities
Software installation, patching and upgrade
Minimum interruption to service
DBA Responsibilities
Install, upgrade your own schema
Support application and multi-server management model

Monitoring and Problem Resolution
Service health is continuously monitored
Hardware, availability, resource usage and etc
Self-healing
Automatic failover
Load-balancing
Dedicated MS operation team 24/7
Service dashboard for up-to-date health status
Relax and just use the service

High Availability and Disaster Recovery
Provide automatic local HA capability
Post V1, provide DR capability
Database is automatically backed up with easy recovery for system errors
Export of data to protect against user errors
“Clone” a database
Post V1, make available “self-service” restore

Database Admin Compatibility Goals
Support common application patterns and TSQL functionality
Support common DBA tasks
Focus on logical data administration
Physical administration provided by service

Logical Administration
Database Schema Design
Database User and Permission Management
Index Management
Query Tuning
Statistics Management
Data Import/Export
Reporting
…
DBA knowledge is compatible with on-premise SQL

Logical vs. Physical Administration
Supported
Create/Drop database
Create/Drop table
Create/Drop user
Index rebuild
Update statistics
…
Not Supported
Database file placement
Filegroup management
Server configuration options
Mirroring
…

Example: CREATE TABLE
CREATE TABLE
[[[ database_name . ] schema_name . table_name
( { <column_definition> |
<computed_column_definition> |
<column_set_definition> }
[ < table_constraint> ] [ ,...n ] )
[ ON { partition_scheme_name … | filegroup | "default" } ]
[ TEXTIMAGE_ON … ]
[WITH ( < table_option > [ ,...n ] ) ]
…
No support for placement ex: FILEGROUP, TEXTIMAGE

Performance Troubleshooting
Detect blocking query and deadlocks
Query optimization
Top N expensive queries
Excessive recompile, bad query plan
Index tuning
Some of existing SQL facilities will continue to work
SET SHOWPLAN
SET STATISTICS
DMV/DMF like system views
…

Management Tooling
Tools that will work
SQL Server Management Studio
SSIS and BCP
SSRS
Tools that will not work in the current form
SQL profiler
SQL performance counter
…
