Motivation

First Prototype

How does this work?

HttpPlatformHandler

• Process management of http listeners
• Proxy request to managing process

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <add name="httpplatformhandler" path="*" verb="*"
                 modules="httpPlatformHandler" resourceType="Unspecified" />
        </handlers>
        <httpPlatform processPath="d:\home\site\wwwroot\go\bin\go.exe" 
                      arguments="run d:\home\site\wwwroot\server.go" 
                      startupTimeLimit="60">
            <environmentVariables>
              <environmentVariable name="GOROOT" value="d:\home\site\wwwroot\go" />
            </environmentVariables>
        </httpPlatform>
    </system.webServer>
</configuration>

Getting More Sophisticated

Site Extensions

Continuous Deployment

Kudu & Git

Outstanding Issues

• Restarting w3wp process on multiple VMs
• Returning the git remote url automatically
• Built-in Go language support 
  • Short term: "go-lite" package
• Automatically handle static resources

Thank you!
