What Is Windows Azure?

What Is An Operating System?

An application execution environment that abstracts away the hardwareA shared file system with access controlResource allocation from a shared poolSupport for powerful programming modelsInter-operability with other systems

What Does An OS Buy You?

Scale (within limits) is freeHardware is someone else’s problemRunning an app == type foo.exe, hit Enter

A set of connected serversOn which developers can:

Install and run servicesStore and retrieve data

What Is The Cloud?

The Reality of Life In The Cloud

Business logic

Datacenter

Respond to hardware failures

Add storage capacity

Handle increase in traffic

Diagnose service failures

Apply OS patches

Perform live upgrade for new feature

Expand to new locale

Service “glue”and operations

…

The Reality of Life In The Cloud

Scale is NOT freeHardware is NOT someone else’s problemRunning an app != type foo.exe, hit Enter

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

….Service 1 Service 2 Service NService 3

……

An operating system that spans & controls a set of connected servers:

Abstract execution environmentShared file systemResource allocationProgramming environments

And more: Utility computing24/7 operationPay for what you useSimpler, transparent administration

What's In The Cloud OS?

A rich, familiar developer experienceA powerful service execution environment

All of the hardware: servers; load balancers; …Virtualized and direct execution

Automated service managementYou define the rules and provide your codeThe platform follows the rules: deploys, monitors, and manages your service

Scalable, available cloud storageBlobs, tables, queues, …

What Does The Developer Get?

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?

A cloud environment in the desktop SDKSupport for a variety of languages

ASP.NET, .NET, native code, PHP, …An ecosystem of tools and support

Integration with Visual Studio, Eclipse, …Logging, alerts, tracing, …Samples, documentation, MSDN, forums, …

Geo-located applicationsMore information: Attend T09F on 3/19

New @ Mix: Full Trust

Applications are no longer restricted to run in medium trust

P/Invoke any native binaryUse more of the .NET stack, e.g. more of WCF

We support FastCGI, so you canAdd native handlers for languages to your appUse the fastCGI path from IIS to run your appe.g. PHP

New @ Mix: Geo-location

Your “cloud project” consists of applications:

0 or more compute services0 or more storage accounts

Windows Azure is in multiple “locales”You can:

Choose a locale for any of your applicationsCreate an “affinity group” to co-locate a set of applications from your cloud project

Available thru developer portal in April

What’s in the model?Service topology and sizeResourcesHealth constraintsConfiguration settings

Service ManagementAutomated

Develop and Model

Deploy and Run

Maintain Service Health

Simple, essential storage abstractions:Large items of data: Blobs, file streams, …Service state: Simple tables, caches, …Service communication: Queues, locks, …

With an emphasis on:Massive scale, availability and durabilityGeo-location and geo-replication

This is not a relational database in the cloudMore information: Attend T08F on 3/19

StorageScalable & Available

Speaking Of Database …

Your cloud services running on Windows Azure will have access to co-located relational database in the cloud

There are multiple target scenariosMore information: Attend T06F on 3/20

Putting It All TogetherArchitectures for scalable, reliable services

Designed to encourage best practicesStateless compute + durable storageCo-location of computation and dataQueues for asynchronous processing

An open platformConnect outbound to any serverOpen protocols and APIs on all components
