Hello Windows Azuredemo
Simple ASP.NET MVC app
Visual Studio 2010
Roles & instances are models in XML config
Local F5 debugging
Deployed to the cloud
Simple portal experience
Staging to production
What you saw…
Environments for your apps
Machines, rack space, switches, connectivity
Automated deployment & configuration
Isolation, redundancy, load balancing

Windows Azure provided…
Windows Azure
Windows Azure is Microsoft’s Cloud Platform for Developers
Operating System for the CloudRuns applications in the cloudProvides StorageApplication Management
Windows Azure ideal for
applications needing:ScalabilityAvailabilityFault ToleranceOn-Demand ComputingPerformance
What is Windows Azure Compute?
Virtual Machines in the CloudThree Flavors:
Web Role Worker Role VM Role
What Can It Run?
Roles and Instances
At runtime each Role will execute on one or more instances A role instance is a set of code, configuration, and local data, deployed in a dedicated VM
Roles are defined in a Hosted ServiceA role definition specifies:VM sizeCommunication EndpointsLocal storage resourcesetc.
Roles and InstancesExample Hosted Service configuration with a single web role and a single worker role
HOSTED SERVICE

VM5 VMn
Fault Domains
99.95% Uptime Guarantee•Requires 2 or more instance per role
Role instance are isolated by fault domain•Fault domains isolate VMs•Fault domains provide redundancy•At least two fault domains per role
The High Scale Application ArchetypeWindows Azure provides a ‘pay-as-you-go’ scale out application platform
Async Activation
Network Activation
Worker Role
Queue Polling Worker•Poll and Pop Messages within while(true) loop•E.g. Map/Reduce pattern, background image processing
Listening Worker Role•Create TcpListener or WCF Service Host•E.g. Run a .NET SMTP server or WCF Service
External Process Worker Role•OnStart or Run method executes Process.Start()•Startup Task installs or executes background/foreground process•Custom Role Entry Point (executable or .Net assembly)•E.g. Run a database server, web server, distributed cache
Web Role
All features of a worker role + IIS 7 or 7.5ASP.NET 3.5 SP1 or 4.0 – 64bitHosts•Webforms or MVC•FastCGI applications (e.g. PHP)•Multiple Websites
Http(s)Web/Worker Hybrid•Can optionally implement RoleEntryPoint
Windows Azure Storage
Scalable storage in the cloud100tb per storage accountAuto-scale to meet massive volume and throughput
Accessible via REST servicesAccess from Windows Azure ComputeAccess from anywhere via internetSupporting .NET Client Library
Various storage typesTable - group of entities (name/value pairs)Queue - Simple non-transactional message queueBlob - Large binary storage Drives - NTFS VHD mounted into Compute instance
SQL Azure Database
SQL Server relational database model delivered as a serviceSupport for existing APIs & toolsBuilt for the cloud with high availability & fault toleranceEasily provision and manage databases across multiple datacenters
SQL Azure provides logical serverGateway server that understands TDS protocolLooks like SQL Server to TDS ClientActual data stored on multiple backend data nodes
SQL Azure Database
Logical optimizations supportedIndexes, Query plans etc..
Physical optimizations not supportedFile Groups, Partitions etc…
Transparently manages physical storage
Building Block Services
Authn support using multiple identity providersEasily integrate Live ID, Facebook, Yahoo, Google, & ADSupport for industry standards and existing .NET APIs
Messaging & connectivity for building distributed and loosely-coupled apps in the cloudEnables hybrid apps across both on-premises & the cloudQueues & Topics for persistence & pub/sub messaging
Distributed, in-memory cache for Windows Azure appsSession state provider for Windows Azure applications.NET client library for caching data
Access Control
Caching
Service Bus
Data Services
Synchronize data from on-premises SQL Server to/from SQL Azure in the cloudSynchronize data between SQL Azure databases potentially in different data centers
SQL Server Reporting provided as a service Reports authored using existing tools (BIDS) Reports can include rich Data Visualizations (Maps, Charts, Tablix) and exported to variety of formats Directly viewed in the browser or rendered as part of an app using the Reporting Viewer controlWeb Service interface to render & manage reports
