Azure Web Sites

Architecture

Azure Web Sites use Azure Cloud Services + load balancer Load-balanced Layer 7 reverse proxy Actual infrastructure

Blob storage Your web site is on here (GRS)

SQL Azure Your web site config + metering is on here

Web Sites are not always in IIS. They only are when requests come!

Provides builds

Provides sandboxing

Provides hosting

Application log streaming

Log streaming All logs from the LogFiles/Application folder

Or configure it when querying: azure log tail <site> -p http

Settings DIAGNOSTICS_LASTRESORTFILE -> file to log to when diagnostics

go wrong DIAGNOSTICS_LOGGINGSETTINGSFILE -> settings file (json) DIAGNOSTICS_TEXTTRACELOGDIRECTORY -> default folder DIAGNOSTICS_TEXTTRACEMAXLOGFILESIZEBYTES-> log rotation

(bytes) DIAGNOSTICS_TEXTTRACEMAXLOGFOLDERSIZEBYTES -> max log

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

or add an environment variable

How do I deploy all tiers in the same website? No .deployment file, just use virtual directories

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, …

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 KUDU_SYNC_CMD + everything you feed it through the management portal

Customizing deploymentsSample deployment script

Great… but why? Deploy an advanced 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?

Post-Deployment scripts https://github.com/projectkudu/kudu/wiki/Post-Deployment-Action-Hooks

Deploy to other regions once the first succeeds

Send an e-mail notification

Update database

Send a Tweet

oRunning Web Jobs(background processes)

Web Jobs There is lots more! http://www.asp.net/aspnet/overview/developing-apps-with-windows-azure/azure-webjobs-recommended-resources

Web Jobs SDK - react to what happens in blob, table, queue

Run jobs continuously Run jobs scheduled Run jobs at interval Run jobs on demand (manual /

API)

class Program {    static void Main(string[] args) {        JobHost host = new JobHost();        host.RunAndBlock();    }

    public static void SquishNewlyUploadedPNGs(        [BlobInput("input/{name}")] Stream input,        [BlobOutput("output/{name}")] Stream output) {        var quantizer = new WuQuantizer();        using (var bitmap = new Bitmap(input)) {            using (var quantized = quantizer.QuantizeImage(bitmap)) {                quantized.Save(output, ImageFormat.Png);            }        }    }}

Conclusion

Key takeaways Azure Web Sites are hosted on Azure, high density
