4 Agenda Data is King Motivation? Why data outside your premise? Microsoft s Data Storage offerings Windows Azure SQL Services Programming & Coding for data on cloud OS What we will not learn? Deep Dive into SQL Services Any SQL Services 2008 specifics Architectural considerations to model data in real life

5 Today s discussion next 60 minutes Windows Azure Storage Services SQL Data

6 HTTP Blobs Tables Queues Application Windows Azure Storage Service Compute Storage Fabric

7 Windows Azure Storage Storage that is Durable Scalable (capacity and throughput) Highly Available Security Performance Efficient Pay for what you use Rich Data Abstractions Service communication: queues, locks, Large user data items: blobs, blocks, Service state: tables, caches, Simple and Familiar Programming Interfaces REST Accessible and ADO.NET

8 Windows Azure Storage Account User creates a globally unique storage account Received a 256 bit secret key when creating account Geo-location & Co-location coming soon Provides security for accessing the store Use secret key to create HMACSHA256 signature for each request Use signature to authenticate request at server Account Blob Table Queue

Blobs Storage Storage Account An account can have many Containers Container A container is a set of blobs Sharing policies are set at the container level Public READ or Private

9 Blobs Storage Storage Account An account can have many Containers Container A container is a set of blobs Sharing policies are set at the container level Public READ or Private Associate Metadata with Container Metadata is <name, value> pairs Up to 8KB per container List the blobs in a container Account sally Container pictures movies Blob IMG001.JPG IMG002.JPG MOV1.AVI

11 Table Storage Table A storage account can create many tables Table name is scoped by account Data is stored in tables A table is a set of entities (rows) An entity is a set of properties (columns) Entity Two key properties that together are the unique ID of the entity in the table PartitionKey enables scalability RowKey uniquely identifies the entity within the partition Account sally Table users photo index Entity

16 Queue Storage An account can create many queues Queue Name is scoped by the account A Queue contains messages No limit on number of messages stored in a queue A message is stored for at most a week in a queue Messages Message size <= 8 KB To store larger data, store data in blob/entity storage, and the blob/entity name in the message

25 Extending SQL Data Platform to Cloud Reporting Business Intelligence Reference Data 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

26 The New SQL Data Services Familiar SQL Server relational model Uses existing APIs & tools 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

27 Accessing SDS User Database connstringbuilder.initialcatalog = "mydatabase"; // Specify your user database to connect Master/Server Database connstringbuilder.datasource = "myserver.data.dev.mscds.com ; // Specify the DNS name of my SDS server master db) connstringbuilder.userid = "jeff@myserver"; // Specify my user id

28 SQL Client (ADO.net) code snippet Just change the connection string values: static void Main(string[] args) { SqlConnectionStringBuilder connstringbuilder = new SqlConnectionStringBuilder(); connstringbuilder.datasource = "myserver.data.dev.mscds.com connstringbuilder.initialcatalog = "mydatabase"; connstringbuilder.encrypt = true; connstringbuilder.trustservercertificate = true; connstringbuilder.userid = "jeff@myserver"; connstringbuilder.password = "****"; string createtablesql TABLE [dbo].[tbl_person] ( [FirstName] NVARCHAR(64) NOT NULL, [LastName] NVARCHAR(64) NOT NULL CONSTRAINT [personname_pk] PRIMARY KEY CLUSTERED ( [FirstName] ASC, [LastName] ASC ) )"; using (SqlConnection conn = new SqlConnection(connStringBuilder.ToString())) { conn.open(); using (SqlCommand cmd = conn.createcommand()) { cmd.commandtext = createtablesql; cmd.commandtype = CommandType.Text; cmd.executenonquery(); conn.close(); } } }
