Cloud Hosting Patterns
Web RoleAzure Web Role – ASP.NET
Web Service RoleAzure Web Role – WCF
Worker RoleAzure Worker Role - .NET
Workflow Role.NET Service Workflow Service - WF

Cloud Hosting –Web Role
Cloud-hosted ASP.NET web site
Can also use Ajax, Silverlight
Accessed over HTTP
“Web Role” in Visual Studio
Windows Azure hosting project
Multiple instances automaticallyload balanced
WEB ROLE(WEB SITE)

Cloud Hosting –Web Service Role
Clouse-hosted WCF web service
Can use SOAP, REST, JSON
Accessed over HTTP

Cloud Hosting –Worker Role
Cloud-hosted background process
.NET background worker thread(s)
No externally accessible endpoint
“Worker Role” in Visual Studio
Workers read from cloud storagefor work items + load balancing
WORKER ROLE
QUEUE STORAGE

Cloud Hosting –Workflow Role
Cloud-hosted workflow
Workflows created with Workflow Foundation in Visual Studio
.NET Service Workflow Project
Workflow uploaded andinstances managed usingAzure Portal
Workflows can communicate viaweb services or Service Bus
Multi-instancing
HOSTED WORKFLOW

Cloud Data Patterns
Cloud Blob StorageWindows Azure Storage Project - Blob Storage
Cloud Queue StorageWindows Azure Storage Project – Queue Storage
Cloud Table StorageWindows Azure Storage Project – Table Storage
Cloud DatabaseSQL Services – SQL Data Services Database

Cloud Data – Blob Storage
Named byte storage
Windows Azure storage project
Container / Blob Item similarto Folder / File
Accessible via REST or .NET code
SDK Storage Client samplecontains .NET code
Available to on-premise apps + cloud apps
BLOB STORAGE

Cloud Data – Queue Storage
Queue storage
Dequeue/delete with time-out
QUEUE STORAGE

Cloud Data – Table Storage
Data Table storage
Table / entities (records)
Partition key / primary key model
TABLE STORAGE

Cloud Data – Database
Cloud-hosted SQL Server Database
SQL Data Services Project
Available to on-premise apps+ cloud apps
Future: Not yet available
SQL SERVER DATABASE

Cloud Communication & Sync Patterns
Load BalancerWindows Azure Hosting Project – Web Roles
Service Bus.NET Services – Service Bus
Live Mesh DesktopLive Services – Live Mesh Desktop / Live Framework
Live Mesh FeedLive services – Live Mesh Feeds / Live Framework

Cloud Communication – Load Balancer
Automatically provided to web roles byWindows Azure Hosting Project
HTTP endpoint
Distribute work to multipleweb roles
Web roles can be web sites orweb services

Cloud Communication – Service Bus
Multi-party communicationrelayed through the cloud
Supports point-to-point andpublish-subscribe communication
Senders and receivers canbe enterprise apps or cloud apps
Integrates with Access Control Service
SERVICE BUS

Cloud Sync – Live Desktop
Synchronizes your ring of computers and devices
Synchronizes both data andmesh web applications
Can view using Live Desktop
Can program against usingLive Framework SDK

Cloud Sync – Live Feeds
Data Feeds SynchronizableAcross Devices
Accessible via AtomPub, RSS
Can program against usingLive Framework SDK
Synchronized with FeedSync

Cloud Security Patterns
Authentication ServiceLive Service – Windows Live ID
Access Control Service.NET Services – Access Control Service

Cloud Security – Authentication Service
Authentication for cloud-hosted web sites
Live Services – Windows Live ID
Windows Azure Hosting Project
Application Live ID registration
Cookie-based identity check
Redirect to Live ID sign-on
Token returned / cookie created

Cloud Composite Application Patterns
Hosted Web Application / with Background WorkersWeb Site front end and Worker Role back end
Hosted Web Service / with Background WorkersWeb Service front end and Worker Role back end
Hybrid Enterprise-Cloud ApplicationEnterprise application that makes use of cloud services
Multi-Enterprise Business Application (MEBA)Cloud-hosted application used by multiple businesses
Hosted Grid Computing ApplicationCloud-hosted grid computing application

How To Create Restful Service in Azure
Create Cloud Web Service (Web Worker)
Add WCF Service (contract, data contracts, implementation)
Decorate service contract with [WebMethod]
Decorate service implementation with [AspNetCompatibilityRequirementsMode]
Implement the client side calls (use jQuery)

Cloud-Extended Enterprise Application
Enterprise-hosted application makes use of cloud services for storage, communication, sync, or security
REST or .NET
Windows Azure Storage
SQL Data Services
.NET Services
Live Services
ENTERPRISE APPLICATION

Multi-Enterprise Business App (MEBA)
A cloud-hosted application used by multiple organizations
Cloud is a 'neutral place'
Front end – web siteand/or web services
Back end – worker rolesand/or workflow
Can leverage any kinds ofcloud storage
Can secure via access control service or traditional membership providers
Must have acute awareness of roles and permissions of organizations and personnel
