What is the cloud?

An approach to computing that’s about internet scale and connecting to a variety of devices and endpoints

Windows Azure

Comprehensive set of services that enable you to build, host and scale applications in Microsoft datacenters

Designed for next generation apps

Windows Azure Overview

Domagoj Pavlešićdizzy.hr

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

Abstraction & Flexibility

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 VM6 VM7 VM8

VM9 VMn

VM1 VM2 VM3 VM4

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
