Agenda What is Windows Azure? What’s new in Windows Azure? Where do you get it?

What Is Windows Azure? It is an operating system for the cloud It is designed for utility computing It provides facilities to: Write your apps (developer experience) Host your apps (compute) Manage your apps (service management) Store your data (storage)

What Is An Operating System? An application execution environment that abstracts away the hardware A shared file system with access control Resource allocation from a shared pool Support for powerful programming models Inter-operability with other systems

What Does An OS Buy You? Scale (within limits) is free Hardware is someone else’s problem Running an app == type foo.exe, hit Enter

What Is The Cloud? A set of connected servers On which developers can: Install and run services Store and retrieve data

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 free Hardware is NOT someone else’s problem Running an app != type foo.exe, hit Enter

What's In The Cloud OS? An operating system that spans & controls a set of connected servers: Abstract execution environment Shared file system Resource allocation Programming environments And more: Utility computing 24/7 operation Pay for what you use Simpler, transparent administration

What Does The Developer Get? A rich, familiar developer experience A powerful service execution environment All of the hardware: servers; load balancers; … Virtualized and direct execution Automated service management You define the rules and provide your code The platform follows the rules: deploys, monitors, and manages your service Scalable, available cloud storage Blobs, tables, queues, …

A cloud environment in the desktop SDK Support 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 applications More information: Attend T09F on 3/19

Mix: Full Trust Applications are no longer restricted to run in medium trust P/Invoke any native binary Use more of the.NET stack, e.g. more of WCF We support FastCGI, so you can Add native handlers for languages to your app Use the fastCGI path from IIS to run your app e.g. PHP

Mix: Geo-location Your “cloud project” consists of applications: 0 or more compute services 0 or more storage accounts Windows Azure is in multiple “locales” You can: Choose a locale for any of your applications Create 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 size Resources Health constraints Configuration settings 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 durability Geo-location and geo-replication This is not a relational database in the cloud More information: Attend T08F on 3/19

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 scenarios More information: Attend T06F on 3/20
