What is Azure?Under the hood of AzureArchitecting apps for Azure

“Packaged”Application

An application that I buy “off the

shelf” and run myself

Self Hosted “Home Built”

An application that I develop and

run myself

Cloud Platform

An application that I develop

myself, but run in the cloud

“Software as a Service”

A hosted application that

I buy from a vendor

On premises vs. CloudOn premises Cloud

Maximum Economy of Scale

Maximum Control

Scale-out not scale-upAdd and remove capacity on demandPay for what you use as you goAutomation is key to reducing costs

Characteristics Of Cloud Computing

The Reality of Life

Business logic

Datacenter

Respond to hardware failures

Add storage capacityHandle increase in traffic

Diagnose service failuresApply OS patchesPerform live upgrade for new featureExpand to new locale

Service “glue”and operations

…

What's Missing?An operating system for the cloud:

….Service 1 Service 2 Service NService 3

Microsoft Cloud Services

Azure™ Services PlatformMicrosoft SharePoint Services

Microsoft Dynamics CRM Services

Microsoft Cloud Services

It is an operating system for the cloudIt is designed for utility computingIt provides facilities to:

Write your apps (developer experience)Host your apps (compute)Manage your apps (service management)Store your data (storage)

What Is Windows Azure?

Inside Azure are many many servers.

with VMs running Windows.

We call this the Fabric,

and it’s where your app runs.

Your Application

Management tasks are automated by the

Fabric Controller.

You tell the Fabric Controller what to do, and it figures out how to do it.

For this to work, you need to tell us about your application.

Defining Your Service

What are the components (roles)?How do they interact?At what scale?

Our Approach to Azure Services

Extend Your Existing Investments Familiar tools, languages, and frameworks with .NET and Visual StudioProvides the choice to build on-premises, cloud, or hybrid solutionsIntegrate with existing assets such as AD and premises applications

Base it on Internet StandardsMultiple protocol support including HTTP, REST, SOAP, AtomPubBroad investment in open, community-based access to Azure services

Provide a Flexible Services Platform with Internet ScaleSimple scenarios are simple – complex scenarios are possible

Services hosted in Microsoft’s data centersDesigned for high availability & scalability

Interoperability

Azure™ Services Platform

Native Code & FastCGI

Run unmanaged code in your Azure hosted applicationsNo longer limits development to .NET languagesRoles can

Select between partial trust or full trustCall native library with P/InvokeSpawn a sub-process

Setting in cloud projects .csdef fileA web role can now use IIS FastCGI module

Architecting apps for Azure

Remember that Azure manages Services not serversHow do you deal with varying loads?How do you deal with failures?

Be prepared to reconstruct local state……since it can disappear any time
