AGENDA

Cloud computing? Windows Azure? Application architecture Getting started Resources Q&A


What’s in the cloud?CLOUD COMPUTING


WHAT IS CLOUD COMPUTING ?

What is cloud computing ? Offering infrastructure, platform and software as a service

over the internet to a global market. Move on-premises management of non functional IT

assets to a provider. Difference from traditional hostings

Sold on demand “pay as you grow” Elastic scalability Service is fully managed by the provider End user centric (IW or developer) Strong focus on integration (cloud-cloud or cloud-on-

premises)


DEFINITION OF CLOUD (NIST)

On-demand self service Standardized access Location independant resource pooling Rapid elasticity Pay per use


IAAS, PAAS, SAAS ?

infrastructure as a service (hardware) Servers available in the cloud, Managed by cloud vendor

platform as a service (developer) Delivery of a OS for custom, cloud enabled apps Support for service hosting and interopability Relational data storage in the cloud

software as a service (end users) Exchange online Sharepoint online Dynamics CRM online

What’s in the cloud?WINDOWS AZURE


THE WINDOWS AZURE PLATFORM

Windows Azure SQL Azure Windows Azure platform AppFabric

Developer tools Microsoft Codename “Dallas”


WINDOWS AZURE

Flexible application hosting Lights-out service management

Provide code & service model, hit ENTER

Storage at massive scale

Compute StorageManagement


SQL AZURE

Relational database as a service Highly available, automatically maintained

Extension of the SQL Server Data Platform

Database

Business AnalyticsReporting Data Sync


SQL AZURE

Relational database, provided as a service Highly symmetrical development and tooling experience (use

TDS protocol and T-SQL) Highly scaled out, on commodity hardware Built on the SQL Server technology foundation

Beyond “hosted database” High availability, DB provisioning, and DB management are

provided by the service Pay for what you use


WINDOWS AZURE APPFABRIC

Secure connections between services Across organizational boundaries

Claims-based access control

!= Windows Server AppFabric (yet?)

ServiceBus

AccessControl


WINDOWS AZURE APPFABRIC - SERVICE BUS

Securely connect applications Over the internet Across any network topology Across organizational boundaries

Primary application patterns Eventing:

Notify applications and/or devices Service Remoting:

Securely project on-premises services out to the cloud Tunneling:

App-to-app communication with NAT/Firewall traversal


SERVICE BUS OVERVIEW


WINDOWS AZURE APPFABRIC - ACCESS CONTROL

Provides outsourcing of claims-based access control for REST web services

Key capabilities: Usable from any platform Low friction way to onboard new clients Integrates with AD FS v2 Supports WRAP / SWT Enables simple delegation

Used today by Service Bus and “Dallas”


ACCESS CONTROL SERVICE


MICROSOFT CODENAME “DALLAS”

Content brokerage and discovery platform Available as a CTP at commercial launch

Microsoft Codename “Dallas”

Information Services


INTRODUCING “DALLAS”

Content Brokerage and Discovery platform Discover, Explore, and Use any type of content (blobs,

structured, real-time web services) Tap into an ecosystem of global content providers Process & analyze data

Empowers developers of all sizes Built on Windows Azure and SQL Azure


Quincy, WA: Complete, approx 500K sq ftSan Antonio, TX: Complete, approx 475K sq ftChicago, IL: Complete, approx 550K sq ftDublin, Ireland: Opening Summer 09, approx 570K sq ftDes Moines, Iowa: Recently announced land purchase




WINDOWS AZURE


Blob

Entities

Messages

WINDOWS AZURE STORAGE CONCEPTS

http://<account>.blob.core.windows.net/<container>

http://<account>.table.core.windows.net/<table>

http://<account>.queue.core.windows.net/<queue>

Account

Container

Table

Queue


BLOB STORAGE

Store sets of binary data Text files, images, …

Highly Available Automatically scales to multiple servers and locations

Durable Data is replicated at least 3 times


TABLE STORAGE

Store sets of structured data Not bound to schema! Billions of entities (rows) and TBs of data Automatically scales to thousands of servers as traffic grows

Highly Available Can always access your data

Durable Data is replicated at least 3 times


TABLE STORAGE CAPABILITIES

What tables don’t do

Not relationalNo Referential Integrity

No JoinsLimited Queries

No Group byNo Aggregations

What tables can do

Transactions (limited)Very Scalable

FlexibleDurable

Store LOTS of stuff Cheap

If these are important to you, use SQL Azure


QUEUE SERVICE

Store a queue of messages FIFO

Can be used by multiple worker roles


WINDOWS AZURE SUMMARY

Many is better than one Let Microsoft worry about this

Loose coupling Web Role and Worker Role

Storage choice Azure Storage: Simple stores scale

Table, Blob, Queue SQL Azure: Full RDBMS

Stored Procedures, Schema, Transactions, Views etc


WINDOWS AZURE - COMING SOON…

Programming model Administrator privileges in the VM Deployment of pre-configured VM images

Still obtain the benefits of the WA service model

Storage User-selectable geo-locations for replicas Secondary indices on tables

Service management Remote terminal server access to VMs


What’s in the cloud?APPLICATION ARCHITECTURE


ARCHITECTURE

Quote: “Some architectures will require rework” All of them will require rework to do it right…

Many application architectures not suited for large scale! I can go for multiple web roles But not for unlimited web roles…

(think performance vs. overhead)

Think in “multiple roles” Web roles Backed by worker roles where needed

Architecture will be one of the challenges
