The Windows Azure Philosophy

Windows Azure is about Scale• Designed from the ground

up for true Internet scale• Offers global presence• Platform for next generation

cloud aware systems• Ride the “network effect”

• LinkedIn: 16 months for first million users, 11 days for most recent million

• Facebook: 5 years to hit 250m users, 8 months to double

• Scale up and scale down

www.flickr.com/photos/ScroffTheBad

Operational Excellence & Elasticity• Need high reliability

• LOB, software as a service• Need massive scale

• Social networking, web 2.0• Have variable load / unpredictable

lifetime• Ticketing, marketing

• Parallel processing• Financial applications

• Don’t fit in well with a company’s data center• Avoid IT dept, support joint ventures

• Benefit from external storage• Archive

• Most architecture is hidden deep inside code

• Windows Azure encourages you to define your application into constituent parts

• Windows Azure supports cloud enabled applications

• Windows Azure can scale the parts of your application as appropriate

Flexible Architecture

• Systems evolve over time• Cloud is not an “all

or nothing” proposition• Hybrid model well

supported• Windows Azure

makes it easier to extend to the cloud

Opening up the Cloud

www.flickr.com/photos/h19/2306213399/in/set-72157594224557858

• Allow developers to apply their existing skills to the cloud

• Support for .NET, Ruby, PHP, Java

• Interoperability with any platform, tools or technology

Flexible Business Model

• No up front hardware purchase

• “Pay as you go” model

• Ideal in current economical climate

Ensure message processing is commutativeMessages will get handled out of order

Judicious use of Try/CatchCheck for poison messagesFor extreme throughput (>500 tps)

Windows Azure Connect• Secure network connectivity

between on-premises and cloud• Supports standard IP protocols

• Example use cases:• Enterprise app migrated to

Windows Azure that requires access to on-premise SQL Server

• Windows Azure app domain-joined to corporate Active Directory

• Roadmap• CTP requires on-premises agent

for non-Windows Azure resources• Connectivity using existing on-

premises VPN devices
