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

Classic IT Capacity problem.
Allocated IT-capacities
Load Forecast
“Under-supply“ of capacities
“Waste“ of capacities
Fixed cost of IT-capacities

Allocated IT capacities
No “under-supply“

Reduction of “over-supply“

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
Storage
Management

SQL Azure
Relational database as a service
Highly available, automatically maintained
Extension of the SQL Server Data Platform
Business Analytics
Reporting
Data Sync
Database

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 ft
San Antonio, TX: Complete, approx 475K sq ft
Chicago, IL: Complete, approx 550K sq ft
Dublin, Ireland: Opening Summer 09, approx 570K sq ft
Des Moines, Iowa: Recently announced land purchase

Windows Azure

Blob

Account
Table
http://<account>.blob.core.windows.net/<container>
Messages
Windows Azure Storage Concepts
http://<account>.table.core.windows.net/<table>
Queue
http://<account>.queue.core.windows.net/<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

Not relational
No Referential Integrity

No Aggregations
Transactions (limited)
Very Scalable
Flexible
Durable
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

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

Architecture will be one of the challenges
