Why Azure?
azure

•   Windows Azure is the foundation of Microsoft’s
    Cloud Platform
• It is an “Operating System in the Cloud” and
  provides Essential Services for the cloud
     Virtualized Computation
     Scalable Storage
     Automatic Management
     Developer SDK

Azure Roles

• An Azure application is implemented with a
  Web and/or a Worker role.
    Developer defines what the role does.
    Azure takes care of the rest.
    Each VM assigner to a role.
Azure Roles
Stateless
• Azure Web Roles must be designer to be
  stateless
    Request from the same user may reach different
     web role instances.
    Store state in Azure storage or client side.
Stateless
Windows Azure data storage

• Azure allow data to be stored in:
    Blobs (large items of user data)
    Tables(simple tables, caches)
    Queues(service communicationz)


• Massive scale, availability and durability.
• Everything is accessible via RESTful services.
Fundamental data
abstractions
• Blobs – Provide a simple interface for storing
  named files along with metadata for the file
• Tables – Provide structured storage;
  A Table is a set of entities, which
  contain a set of properties
• Queues – Provide reliable storage and delivery
  of messages for an application
Windows Azure data storage
Windows azure tables

• Provides Structured Storage
    Massively Scalable Tables
      • Billions of entities (rows) and TBs of data
      • Can use thousands of servers as traffic grows
    Highly Available
      • Can always access your data
    Durable
      • Data is replicated several times

• Familiar and Easy to use API
    ADO.NET Data Services – .NET 3.5 SP1
      • .NET classes and LINQ
      • REST – with any platform or language
Agenda

• Data model
• Demo – creating Tables
• Demo – creating Blobs
• Demo – creating Queues
• Basic CRUD using .NET and REST
• Best Practices
• Demo – A better Approach
Data model

• 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
     • PartitionKey – enables scalability
     • RowKey – uniquely identifies
       the entity within the partition
partition




Table Partition – all entities in table
  with same partition key value
Application controls granularity of partition

Table Partition – all entities in table
  with same partition key value
Application controls granularity of partition
Partiton guidelines

• Performance
    Use a PartitionKey that is
     common in your queries
      • Entities with same partition key value are
        clustered

• Scalability
    We monitor partition traffic
    Automatically load balance partitions
      • Each partition can potentially be
        served by a different storage node
      • Scale to meet the traffic needs of your application
    More partitions – makes it easier
     to balance load

entities and properties

• Each Entity can have up to 255 properties
• Every Entity has fixed key properties
    Partition key
    Row key
• No fixed schema for rest of properties
    2 entities in the same table
     can have different properties
    Properties stored as <Name, TypedValue> pairs
• Each entity has a system maintained version
Automated service
management
• Our responsibilities
    Develop and model the service.
    Deploy the service to the cloud.
    Configure the settings and constraints.
• Azure’s responsibilities
    Run the service.
    Maintain the service’s health.
    Configure the settings and constraints.

Property types

• Partition key and Row key
    String (up to 64KB)
• Other properties
    String (up to 64KB)
    Binary (up to 64KB)
    Bool
    DateTime
    GUID
    Int
    Int64
    Double
