What is SQL Server Data Services?

Application Agility

• Simple, flexible data model• REST and SOAP protocols support

Business Ready SLA

• Built using robust Microsoft SQL Server technology• SLA for business continuity• Highly available, reliable

and secure

Microsoft® SQL Server® Data Services (SSDS) is aWeb facing data storage and processing utility

Scales without Limits

• Storage and processing scales without restrictions• Businesses pay only for the resources consumed

Application Agility

• Simple, flexible data model• REST and SOAP protocols support

Business Ready SLA

• Built using robust Microsoft SQL Server technology• SLA for business continuity• Highly available, reliable

and secure

SSDS Key Concepts ("ACE")Authority

– Unit of geo-location and billing– DNS sub domain per container– Collection of containers

Container– Unit of consistency/search– Collection of entities– No schema required

Entity– Property bag of name/value pairs– Unit of update/change

Authority

Container

Entity

8

Entity ConceptsFlexible Entity Model

– No schema required– Smallest Unit of Storage (unit of update)

Metadata properties– ID – unique within parent container– Kind – track user type ex: JobListing, Resume, etc– Version – update timestamp on each operation

Flex properties– Can change instance type or add additional properties– Support for simple types: decimal, string, bool, etc– All properties are indexed

Container ConceptsStores Flexible EntitiesUnit of consistencyWidest domain of a single search and operation

11

Authority ConceptsA collection of ContainersAnalog to namespaceUnit of billing and geo-locationHas one DNS name

Authority

12

Webservice API

Consumed using SOAP or REST– Endpoint secured by SSL– Each authority has single owner

– Secured using single owner credentials– Aligning REST interface with conventions used by ADO.NET

Data Services

Web Service API (REST)Service: https://data.sitka.microsoft.com/v1

CreateAuthority (POST)Authority: https://auth.data.sitka.microsoft.com/v1

FetchAuthority (GET)QueryContainers (GET) with query “from e in … where …”CreateContainer (POST)

Container: https://auth.data.sitka.microsoft.com/v1/containerId FetchContainer (GET) QueryEntities (GET) with query “from e in … where …” UpdateContainer (PUT)DeleteContainer (DELETE)CreateEntity (POST)

Entity: https://auth.data.sitka.microsoft.com/v1/containerId/entityId FetchEntity (GET)UpdateEntity (PUT) DeleteEntity (DELETE)

14

Refining Webservice APIs

Conditional requests & Entity VersioningOptimistic concurrency

Blob supportStore media, files, etc in SSDS

What else is needed?

15

Building An Application

Concept Usage ExampleAuthority Single location for Litware applications LitwareHR

Container Container for app runtime, one container per tenant

LiwareHR_MetadataContosoHR, …

Entity Storage for each app type – jobs, resumes and various metadata items

JobListingApplication

Litware HR – a web-based recruiting serviceMulti-tenant application

– Contoso (Web Startup)– AdventureWorks (Bike Store)

Roles– HR Manager and Job Applicant

16

When do I get to use it?Currently in invitation only beta

– No charge for use during beta period– Next step – open beta

Service refresh every 8 weeks or so– New functionality based on customer feedback

Go Live in H1’09– Published SLA– Pricing and licensing model is TBD

SummaryThis is the starting point

– Scale, cost and operations excellence– Learn about customer and partner usage patterns

Built on proven Windows Server and SQL Server technology– Industrial strength servers; used learning from our large scale MSN and

Live services– Distributed data fabric for scale out and lights out operation

Service will evolve based on feedback and partnerships– Rich data types and query– Blobs and full text search– Rich services: reporting, analytics, caching, sync and data quality– We are extending our data platform to the Cloud
