DESCRIPTION
Microsoft has a cloud platform which runs .NET, NodeJS and PHP. All 101 talks out there will show you the same: it’s easy to deploy, it scales out on demand and it runs WordPress. Great! But what about doing real things? In this session, we’ll explore the things they don’t teach kids in school. How about trying to find out the architecture of this platform? What about the different deployment options for Windows Azure Web Sites, the development flow and some awesome things you can do with the command line tools? Did you know you can modify the automated build process? Join me in this exploration of some lesser known techniques of the platform.

Windows AzureWeb Sites
Architecture
Load balancer Layers 1st layer: Windows Azure load balancer 2nd layer: IIS + ARR
ARR “Reverse proxy” Verifies hosting database (plans, quotas, …) Negotiates best node to run your site on Site not used much? Put it on a highly loaded machine
Web servers %SYSTEM32%\inetsrv\config\applicationHost.config is taken out of the loop SQL Azure No refreshing of all app pools when file is saved
Storage “File share” hosted on other machines Using “WA drive” on blob storage
Dynamic website activation service Verifies runtime database (plans, quotas, …) Site not used for a while? Remove it from the server
Web Sites are not in IIS. They only are when a request comes
in!

Multi-tierDeploying a specific project file
Multi-tier remarks… One .deployment file per branch [config]project=MultiTier.WebApi/MultiTier.WebApi.csproj
How do I deploy all tiers in a separate website? .deployment file per branch and every tier in a branch or customize the build
Customizing the build process Check https://github.com/projectkudu/kudu/wiki/Deployment-hooks
.deployment file [config]command=<whatever command>
Write in batch file, bash script, PHP, JavaScript, …

Customizing deploymentsAn introduction
What can I do in scripts? A lot :-) (but not too much… there’s a sandbox)
Environment variables: DEPLOYMENT_SOURCE DEPLOYMENT_TARGET DEPLOYMENT_TEMP WEBROOT_PATH MSBUILD_PATH + everything you feed it through the management portal

Customizing deploymentsSample deployment script
Great… but why? We’ve seen the multi-tier scenario
We can download stuff (NuGet package restore, pull in external Git repos before build)
We can run stuff (msbuild, nuget.exe, curl, php, node, …)

Customizing deploymentsWhat about running unit tests?

A private Kudu build in web sites?
Build and FTP the artifacts/debug/KuduService to your website
Add USE_PRIVATE_KUDU=1 app setting
Enjoy the ride! (but don’t call support, you’re on your own)

A private Kudu build in web sites?
Conclusion
Key takeaways Windows Azure Web Sites are high density
Hosted on Cloud Services
Kudu is our best friend Settings and secrets Muliple environments Multiple tiers Build customization Unit tests Kudu-in-Kudu
