1 Answer “What is Windows Azure?”

2See how to get started & build your first app

3Understand the key Windows Azure concepts

What is Windows Azure?

Comprehensive platform for developing cloud appsHost and execute your code in the cloudProvides application managementIncludes services for storage, access control, etc.

Key BenefitsAbstraction & flexibilityDesigned for scalability & high availabilityOpen & InteroperableMix and match servicesConsumption based pricing model

Windows Azure ScenariosIdeal for applications needing:ScalabilityAvailabilityFault Tolerance

Service Definition

Service Configuration

Your Code

Service, Roles, and InstancesA service is a logical set of roles (up to 5)Defined in the Service Definition at development timeAssigned a public URL (i.e. foo.cloudapp.net) at deployment

Instances

Role defines the type of Virtual Machine that will be used to run each component of your applicationDefined in the Service Definition at development time

An instance is a dedicated virtual machine instance that is running your code with your configurationInstances are created by the Windows Azure fabric at runtime based on the roles defined in the service definition

Roles

Service

Role TypesGeneral purpose host for executing code or an executableImplement code in a Run methodSimilar to a Windows ServiceHost your own web server, encoder, etc.Typically used for background processing

Designed for web sites/services accessible using HTTPProvides all features of a worker role and IIS 7 or 7.5Execute ASP.NET, WCF, PHP, etc.Can include multiple web sites in the same roleOptionally implement RoleEntryPoint

Compute Instance SizeSelectable Size defines CPU Cores, RAM, Local Storage, and PricingSize configured in the Service Definition prior to packaging

Key considerationsDon’t just throw big VMs at every problemScale out architectures have natural parallelismMore small instances == more redundancySome scenarios will benefit from more cores

Windows Azure Deployment

Each hosted service can have two deployments: Production & Staging

Deployments performed through:Windows Azure Platform PortalVisual StudioREST Service Management APIsPowerShell cmdlets/scripts

Deployment outside of the portal requires management cert to be associated with the Windows Azure subscription

Upgrading Your Application

VIP SwapUses Staging and Production environments

Allows to quickly swap environments

Simply changes which deployment the load balancer uses to service requests

In-Place UpgradePerforms a rolling upgrade on live service

Entire service or a single role

Manual or Automatic across update domains

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 cloud

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
