2 SQL Server Data Services Working the Cloud Mike Flasko Program Manager, Microsoft

3 Agenda Why "data services"? Your data service options SQL Server Data Services – Value proposition – Key Concepts – How to use the service Release Plan Summary & Resources

4 Why Data Services HTML + Javascript Data (XML, etc) AJAX / RIA Applications Mashup UI Data Feeds Mashups Data (XML, etc) Online Services Data (XML, etc) Data Driven Web Applications

5 Data Services Vision SYNC SYNCSYNCSYNC ADO.NET Data Services Framework On Premises Internet Standard Interfaces and Protocols (SOAP, REST) Mobile and Desktop Client Applications Web Services / Mid Tiers SQL Server Data Services (SSDS) ADO.Net Data Services Windows Live Services (Photos, etc) Windows Live Services (Photos, etc)

6 What is SQL Server Data Services? Application Agility Simple, flexible data model Simple, flexible data model REST and SOAP protocols support REST and SOAP protocols support Application Agility Simple, flexible data model Simple, flexible data model REST and SOAP protocols support REST and SOAP protocols support Business Ready SLA Built using robust Microsoft SQL Server technology Built using robust Microsoft SQL Server technology SLA for business continuity SLA for business continuity Highly available, reliable and secure Highly available, reliable and secure Business Ready SLA Built using robust Microsoft SQL Server technology Built using robust Microsoft SQL Server technology SLA for business continuity SLA for business continuity Highly available, reliable and secure Highly available, reliable and secure Microsoft ® SQL Server ® Data Services (SSDS) is a Web facing data storage and processing utility Scales without Limits S torage and processing scales without restrictions S torage and processing scales without restrictions Businesses pay only for the resources consumed Businesses pay only for the resources consumed Scales without Limits S torage and processing scales without restrictions S torage and processing scales without restrictions Businesses pay only for the resources consumed Businesses pay only for the resources consumed Application Agility Simple, flexible data model Simple, flexible data model REST and SOAP protocols support REST and SOAP protocols support Application Agility Simple, flexible data model Simple, flexible data model REST and SOAP protocols support REST and SOAP protocols support Business Ready SLA Built using robust Microsoft SQL Server technology Built using robust Microsoft SQL Server technology SLA for business continuity SLA for business continuity Highly available, reliable and secure Highly available, reliable and secure Business Ready SLA Built using robust Microsoft SQL Server technology Built using robust Microsoft SQL Server technology SLA for business continuity SLA for business continuity Highly available, reliable and secure Highly available, reliable and secure

7 SSDS Key Concepts ("ACE") A uthority – Unit of geo-location and billing – DNS sub domain per container – Collection of containers C ontainer – Unit of consistency/search – Collection of entities – No schema required E ntity – Property bag of name/value pairs – Unit of update/change AuthorityContainerEntity

8 Entity Concepts Flexible 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

9 Flexible Entity Example PropertyTypeValue MetadataIDEntityIdVWGOLF-01 KindEntityKindCar FlexPropsDescriptionStringReliable, one owner, … PriceNumeric ListingDateDatetime LocationZipString98052 PropertyTypeValue MetadataIDEntityIdMINICOOPER-264 KindEntityKindFunCar FlexPropsDescriptionStringReliable, one owner, … PriceNumeric ListingDateString1 st January, 2008 LocationZipString98052 EngineSizeNumeric1600 Additional property Different instance types Different Kinds

10 Container Concepts Stores Flexible Entities Unit of consistency Widest domain of a single search and operation

11 Authority Concepts A collection of Containers Analog to namespace Unit of billing and geo-location Has 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

13 Web Service API (REST) Service: CreateAuthority (POST) Authority: FetchAuthority (GET) QueryContainers (GET) with query “from e in … where …” CreateContainer (POST) Container: FetchContainer (GET) QueryEntities (GET) with query “from e in … where …” UpdateContainer (PUT) DeleteContainer (DELETE) CreateEntity (POST) Entity: FetchEntity (GET) UpdateEntity (PUT) DeleteEntity (DELETE)

14 Refining Webservice APIs Conditional requests & Entity Versioning Optimistic concurrency Blob support Store media, files, etc in SSDS What else is needed?

15 Building An Application ConceptUsageExample AuthoritySingle location for Litware applicationsLitwareHR ContainerContainer for app runtime, one container per tenant LiwareHR_Metadata ContosoHR, … EntityStorage for each app type – jobs, resumes and various metadata items JobListing Application Litware HR – a web-based recruiting service Multi-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

17 Microsoft Data Platform Roadmap Mobile and Desktop OLAP FILE XML RDBMS Query Analysis Reporting Integration Synch Search Server Data Services

18 Summary This 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
