Why should I bet my business on it?
Consumption-based model (TBA Summer 09)You pay only for what you useNo minimum or long term commitmentAn inexpensive way to experimentEasy to grow as your business grows
Managed elastic capacity and scalabilitySimpler operating and management environment for developersIntegrates well with on-premises applications and servicesLeverages existing technology investments and skills

Microsoft Cloud Services Overview
Three categories:Online (+)LiveAzure Services Platform
Online +
Microsoft or partner hosted versions of on-premise software. Most carry “Online” moniker. (Some do not )Hosted services include:
Exchange Online and Exchange Hosted ServicesSharePoint OnlineOffice Communications Online (not available yet)Live MeetingDynamics CRM Online
Live
Large set of Microsoft based servicesSubscribed to by an Aggregator (which could also be Microsoft as in the case of the Windows Live portalFor adding functionality to web sites the Aggregators offers up to Internet clients.
Azure Services Platform
Used to build distributed applications and data which may involve on-premise and cloud based components. It provides:
Cloud based Execution of ASP.NET and batch applicationsMultiple Storage types, Database, Internet message relay and pub/subWorkflow

Windows Azure Storage
Massive scale and low costDurable, available, scalable and secureRedundant copies, commodity hardware, layered architecture
Blobs: Simple interface for storing named files along with metadata for the fileTables: Structured storage. A set of entities, which contain a set of properties. PartitonableQueues: Reliable storage and delivery of messages for an application
Windows Azure Storage: Blobs
Store Large Objects (up to 50 GB each)Account/Container/Blob/Block naming
Standard REST Put/Get InterfacePutBlob(BlobName, stream, size)
Overwrites the existing blob by that name
GetBlob(BlobName, starting offset, length)DeleteBlob(BlobName)
Associate Metadata with BlobMetadata is <name, typed value> pairsSet/Get with or separate from blob data bitsUp to 8KB per blob
Streaming a Blob via Blocks

Windows Azure Storage: Tables
Windows Azure Storage: Tables
Structured storage in the form of TablesA Table is a set of entities (rows)An Entity is a set of properties (columns)
NamespaceAccount Name– Table Name
Entity (PartitionKey, RowKey)Table Name
You give a unique name to each Table, which is scoped by AccountAn account can create many tables
Focus is to provide Scalable Structured Storage via TablesNot a relational database (e.g., no foreign keys, no joins, etc)
Windows Azure Storage: Tables
Your table can grow to be billions of entities (rows) and TBs of data
The table may need to be spread across thousands of servers to handle traffic to that table
Partitioning is how we spread the table out
The Table’s entities are broken into partitions

Scaling Tables through Partitions
Table’s entities are broken up into PartitionsPartition: set of entities with same partition key value
PartitionKey – unique ID for the partition within the TableRowKey – unique ID for the row within the partitionAll Queries are sorted by Partition Key and then by Row Key
Each partition can be served by different nodes
Partition 1
Partition 2
27
Why Partition?
Entity LocalityEntities in the same partition will be stored together for efficient querying and cache locality when accessing
Table ThroughputTable Storage automatically performs partition load balancing based upon the partition key Scale to meet the traffic needs of your application

Windows Azure: Queues
Provides reliable queued message deliverySimple, asynchronous work dispatch via queuesThe programming semantics ensure that a message is retrieved at least once
Queue access provided via RESTAccount can contain QueuesQueue contains MessagesURL: http://<Account>.queue.core.windows.net/<QueueName>
Queues contain MessagesMessage Size <= 8 KBMessages can contain references to blob/table storage29
