Q: Why this topic?

A: This is the most uncovered topic so far…

Back to BasicsQ: What is Cloud?

A: Elastic compute resource on demand

A: This is not a technology, this is a THINKING

Cloud as a way of THINKING

Existing technologies adopted in a new way

Utility model is welcomed by small companies and enterprises

But I Can’t Use SQL Azure!

Let’s say for security reasons…

Hybrid Windows Azure Model

Your applications can be

Entirely On-Premises

Entirely in the Cloud

Both in the Cloud and On-Premises

Hybrid Windows Azure Model

Cloud On-premises

Windows Azure Connect

Windows Azure Connect

Windows Azure Connect

Secure connectivity

Super simple setup

Active Directory support

But I Need Customizations!

Configure Windows, Install Applications, etc…

Admin Mode & Startup Tasks

Execute BAT and PowerShell scripts

Configure Windows Server and IIS

Install additional software

Update registry keys

“PING in the Cloud”

Admin Mode & Startup Tasks

<WebRole name="WorkerRole1"> <Startup> <Task commandline="relative\path\ToSetupExecutable" executionContext="limited|elevated" taskType="simple|foreground|background"/> </Startup></WebRole>

Let’s Have Some FUN!

And give away some prizes for…

Yell “I LOVE Windows Azure”

I told you my talks are a little bit crazy…

OK, Let’s Continue…

But <your excuse here>

… and Startup Tasks can’t help you

VM Role

Ability to upload customized Windows Server x64 2008 R2 Enterprise image

You are now responsible for patching and maintenance

OS image is not durable (yet)

VM Role

It’s NOT an Infrastructure as a Service!

Windows Azure does automate many management tasks

Recap: Moving Apps to the Cloud

It’s really easier than you thought, isn’t it?

Moving Applications to the Cloud Use Remote Desktop for easier

diagnostics

Use Azure Connect to interconnect cloud and on-premise applications

Use Admin Mode and Startup Tasks to customize Windows and install software

Use VM Role to migrate legacy and native applications

Thank You!
