Development

Environment

• OS: Vista+

• Must enable local IIS

features

• Visual Studio 2008+

• Must run as local

Admin

• .NET 3.5 sp1

• Local SQL instance

Azure SDK

• Provides local devfabric

and dev storage

• Complete local

simulation of the cloud

fabric

• 90% of the local

devfabric is the same as

the cloud fabric

• Includes handy project

templates

• Deployment and

management tools

• Includes client storage

library

AppFabric SDK

• Provides libraries and

tools to use ACS and

Service Bus

• Includes ACM.exe and

AF Configuration

source.

Computation = CPU • Provides application

scalability. • Web and Worker roles. • Scale Up and Down the

processing power.

Storage Services • Store large amount of

data • Format from Image to

text • Paying for what they use

or store.

The Fabric Controller • Automates load balancing and computes

resource scaling. • It communicates with every server within

the Fabric. • Monitors application and optimizing

hardware utilization.

• Interacts with a “Fabric

Agent” on each machine

• Monitors every VM,

application and instance

• Performs load balancing,

check pointing and recovery

Fabric Controller

The Fabric Controller

automates service

management

GOAL: SCALABILITY Scale out by replicating instances as

needed.

Allow applications to scale

user and compute processing

independently.

Two instance types: Web Role & Worker Role Windows Azure applications are built with web role instances, worker role instances, or a combination of both.

Each instance runs on its own VM (virtual machine), replicated as needed.

Compute in Windows Azure

GOAL: SCALABLE, DURABLE STORAGE

Windows Azure storage is an

application managed by the

Fabric Controller

Windows Azure applications can use

native storage or SQL Azure

Blobs: large,

unstructured

data (audio,

video, etc)

Tables: simply

structured data,

accessed using

ADO.NET Data

Services

Queues: serially accessed

messages

or requests, allowing

web-roles and worker-

roles to interact

Each item in storage is stored in triplicate.
