Developer ExperienceUse existing skills and tools.


ROLE OPTIONS

An application consists of one or more roles• A running application executes multiple instances of

each role• The fabric manages role instances

Windows Azure: Compute

WORKER ROLE

Designed for arbitrary tasksAccepts input via:• HTTP/HTTPS• Any TCP Port

WEB ROLE

Designed to handle Web requests• ASP.NET• WCF• Fast CGI +

PHP• …

Accepts input via HTTP/HTTPS

VM ROLE

The role is the VM. Suitable for:• Long running

application installations.

• Application installations requiring manual interaction.

• You configure and maintain the OS.


Windows Azure: Storage

QUEUES• Simple message queue

• Not transactional• Read at least once

• Delete to remove message, otherwise is returned to queue

TABLES• Table = group of entities• Entity = name/value pairs• Partitioned by key

• Scales to billions of entities

• Not a relational DBMS

BLOBS• Large binary storage• Stored in container

• Unlimited containers• Deliverable through

content delivery network (CDN)

DRIVES• NTFS VHD mounted into

Compute instance• Read/Write 1:1• Read only 1:N

• Backed by blob


Windows Azure: Storage

Scalable storage in the cloud

• 100 terabytes per Storage account• Auto-scale to

meet massive volume and throughput

Accessible via RESTful Web

services• Access from

Windows Azure applications• Access from

anywhere via internet

Various storage

types• Tables• Blobs• Queues• Drives


SQL Azure Database

SQL Azure provides logical SQL Server• Gateway server that understands TDS protocol• Looks like SQL Server to TDS Client• Actual data stored on multiple backend data nodes

Logical optimisations supported• Indexes, Query plans etc..

Physical optimisations not supported• File Groups, Partitions etc…

Transparently manages physical storage


Windows Azure AppFabric: Service Bus

• Exchange messages between loosely coupled applications• Network send/receive from any internet connected device• Traverse NAT/Firewall• Message buffering for loosely connected applications

Send Receive

SERVICE BUS

Receive Send

Windows Azure AppFabric: Access Control

Data and Applications

Applications or Users

Provide abstraction for

federated claims-based authentication.

Easily establish secure trust relationship.

Simplify and automate

complex authorization schema requests.

Designing Windows Azure

Applications


Basic Design Principles for the Cloud• Scaling-out instead of Scaling-up (Design for

failure)

Vs …….


Basic Design Principles• Decouple components using Async Patterns.

Why Use Asynchronous Patterns?

• Improve apparent responsiveness• Perform long running work in

background• Return immediately to the client• Absorb spikes in load


Building Windows AzureApplications


Windows Azure Platform Development Prerequisites for .Net apps• Windows Azure Tools for Microsoft Visual Studio

(Version 1.4)

http://www.microsoft.com/download/en/details.aspx?id=26940

Follow instructions on Microsoft downloads page

- Microsoft Windows 7, Windows Server 2008, Windows Server 2008 R2.

- Microsoft Visual Studio Professional 2010 (or above) or Express.

- Enable IIS7 with ASP.NET and WCF HTTP activation.- Windows Azure SDK 1.4 (March 2011 edition)- Recommended: Windows Azure AppFabric SDK v1.0

DEMO

Role Programming ModelInherits RoleEntryPointOnStart() Method

Called by Fabric on startup, allows you to perform initialization tasks.Reports Busy status to load balancer until you return true.

Run() MethodMain logic is here – can do anything, typically infinite loop. Should never exit.

OnStop() MethodCalled when role is to be shutdown, graceful exit.30 Seconds to tidy up


What Azure provided

Demo Recap

• Simple ASP.NET app• Visual Studio 2010• Roles & instances are

models in XML config• Local F5 debugging• Deployed to the cloud• Switched from staging

to production

• Environments to run your apps

• Machines, rack space, switches, connectivity

• Automated deployment & configuration

• Isolation, redundancy, load balancing

• Abstraction & Flexibility

Guestbook Sample Application


Guestbook Sample Application

1. User uploads large image file2. Image inserted into blog storage3. Message placed on queue including

BLOB URI and metadata4. Worker role is polling queue. Reads

message from queue5. Worker role processes message, reads

from BLOB storage, generates thumbnail

6. Thumbnail and metadata stored in Table storage

7. Message deleted from queue


Deployment options

• Create and deploy Azure Package manually.• Deploy from Visual Studio using Certificates.• Command Line and PowerShell.• Built using the Service Management API.


Monitoring / Debugging Options

• Enable Remote Desktop.• Enable Intellitrace (only for .Net 4.0 Azure apps and VS2010 Ultimate).• Enable / Use Windows Azure Diagnostics.
