Provides security for accessing the store Use secret key to create HMACSHA256 signature for each request

Use signature to authenticate request at server

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

Table StorageTable

A storage account can create many tables

Table name is scoped by account

Data is stored in tablesA table is a set of entities (rows)

An entity is a set of properties (columns)

EntityTwo “key” properties that together

are the unique ID of the entity in the

tablePartitionKey – enables scalability

RowKey – uniquely identifies the

entity within the partition

Tables - Capabilities

What tables don’t do

Not relational

No Referential Integrity

No Joins

Limited Queries

No Group by

No Aggregations

No Transactions

No Transactions

What tables can do

Cheap

Very Scalable

Flexible

Durable

If these are important to you, use:

What tables contain

Partition key & Row key

Timestamp

255 properties for your data & data of size 1MB

Query a Table

LINQDataServiceContext context = new DataServiceContext(‚http://myaccount.table.core.windows.net‛);

var customers = from o incontext.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’

Queue Storage

An account can create many queuesQueue Name is scoped by the account

A Queue contains messagesNo 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>

MessagesMessage size <= 8 KB

To store larger data, store data in blob/entity storage, and the blob/entity name in the message

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

Accessing SDS

User DatabaseconnStringBuilder.InitialCatalog = "mydatabase";

// Specify your user database to connect

Master/Server DatabaseconnStringBuilder.DataSource = "myserver.data.dev.mscds.com“;

// Specify the DNS name of my SDS server master db)

connStringBuilder.UserID = "jeff@myserver";

// Specify my user id

SQL Client (ADO.net) code snippetJust change the connection string values:static void Main(string[] args) {

SqlConnectionStringBuilder connStringBuilder = new SqlConnectionStringBuilder(); connStringBuilder.DataSource = "myserver.data.dev.mscds.comconnStringBuilder.InitialCatalog = "mydatabase"; connStringBuilder.Encrypt = true; connStringBuilder.TrustServerCertificate = true; connStringBuilder.UserID = "jeff@myserver"; connStringBuilder.Password = "****";

string createTableSql = @"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 ) )";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();

}}}
