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

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 Account Container Blob
• Up to 8KB per container

• List the blobs in a container pictures

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
Account Table Entity
are the unique ID of the entity in the
table users
PartitionKey – enables scalability
RowKey – uniquely identifies the sally
entity within the partition photo
index

12. Windows Azure Storage
A closer look at tables

13. Tables - Capabilities
What tables don’t do What tables can do
 Not relational  Cheap
 No Referential Integrity  Very Scalable
 If these No Joins
are important  Flexible
 to you, use:Queries
Limited  Durable
 No Group by What tables contain
 No Aggregations Partition key & Row key
 No Transactions Timestamp
255 properties for your data & data
 No Transactions of size 1MB

14. Query a Table
LINQ
DataServiceContext context = new
DataServiceContext(‚http://myaccount.table.core.windows.net‛);
var customers = from o in
context.CreateQuery<Customer>(‚Customer‛)
where o.PartitionKey == ‚Lee‛
select o;
foreach (Customer customer in customers) { }
GET http://myaccount.table.core.windows.net/Customer?
$filter= PartitionKey eq ‘Lee’

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
http://<Account>.queue.core.windows.net/<QueueName>
Messages
Message size <= 8 KB
To store larger data, store data in blob/entity storage, and
the blob/entity name in the message

17. Dequeue and Delete Messages
Producers Consumers
P2 C1 1. Dequeue(Q, 30 sec)  msg 1
4 3 2 1
C2
P1
2. Dequeue(Q, 30 sec)  msg 2

18. Dequeue and Delete Messages
Producers Consumers
P2 1 C1 1. Dequeue(Q, 30 sec)  msg 1
5. C1 crashed
6. msg1 visible 30 seconds after Dequeue
4 3 2 1
2
C2
P1
2. Dequeue(Q, 30 sec)  msg 2
3. C2 consumed msg 2
4. Delete(Q, msg 2)
7. Dequeue(Q, 30 sec)  msg 1

20. Windows Azure Data Storage Concepts
Container Blobs
http://<account>.blob.core.windows.net/<container>
Account Table Entities
http://<account>.table.core.windows.net/<table>
Queue Messages
http://<account>.queue.core.windows.net/<queue>

25. Extending SQL Data Platform to Cloud
Business Reference
Reporting Intelligence 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 = quot;mydatabasequot;;
// Specify your user database to connect
Master/Server Database
connStringBuilder.DataSource = quot;myserver.data.dev.mscds.com“;
// Specify the DNS name of my SDS server master db)
connStringBuilder.UserID = quot;jeff@myserverquot;;
// 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 = quot;myserver.data.dev.mscds.com
connStringBuilder.InitialCatalog = quot;mydatabasequot;;
connStringBuilder.Encrypt = true;
connStringBuilder.TrustServerCertificate = true;
connStringBuilder.UserID = quot;jeff@myserverquot;;
connStringBuilder.Password = quot;****quot;;
string createTableSql = @quot;CREATE TABLE [dbo].[tbl_Person] ( [FirstName] NVARCHAR(64) NOT NULL,
[LastName] NVARCHAR(64) NOT NULL CONSTRAINT [personName_PK] PRIMARY KEY CLUSTERED (
[FirstName] ASC, [LastName] ASC ) )quot;;
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();
}
}
}

29. Example of SQL Compatibility
In Scope for v1 (likely) Out of Scope for v1 (likely)
Tables, indexes and views Distributed Transactions
Stored Procedures Distributed Query
Triggers CLR
Constraints Service Broker
Table variables, Spatial
session temp tables (#t) Physical server or catalog
… DDL and views
