CD - Making it work with Windows and .NET

Co-Presented with Matthew Skelton (http://twitter.com/matthewpskelton).

The technologies and approaches for Continuous Delivery are essentially identical across different operating systems, but some things need special treatment for Windows and .NET. When Jez Humble and Dave Farley published their groundbreaking book 'Continuous Delivery' in 2010, many of the tools described were either nonexistent on the Windows platform or did not support the rich automation capabilities they do now.

This talk aims to encourage many more teams working with Windows and .NET to adopt Continuous Delivery by sharing real-world success stories of organisations using Windows and .NET for Continuous Delivery; the speakers share their first-hand experience in different organisations and also explore some case studies from the new O'Reilly eBook 'Continuous Delivery with Windows and .NET'.

5. CDwithWindows.net Why a special focus for .NET?
6. CDwithWindows.net Windows/.NET around 2010 • No native Package Management • Very limited automation • Point and click configuration • Monolithic configuration (SCCM etc.)
7. CDwithWindows.net
8. CDwithWindows.net Windows/.NET in 2016 • PowerShell APIs for all MS products • NuGet, Chocolatey, OneGet, … • 1st-class Git experience on Windows • Native Windows/.NET support in Chef, Puppet, Ansible + DSC

24. CDwithWindows.net Takeaways from • Collect metrics from your live systems • Make them effective for issue resolution • Too much unstructured data can be blinding • Help your future selves pinpoint issues quickly and easily • Continually review and revise effectiveness of existing dashboards

27. CDwithWindows.net Parting gifts from • Git on Windows works very well • Chef on Windows works very well • GoCD on Windows works very well • Github + TeamCity + GoCD == awesomeness • At web scale, SaaS logging tools cost $$$, so invest in internal ELK at the right time

30. CDwithWindows.net
31. CDwithWindows.net Discoveries from • Installation experience is a feature • Chocolatey is still a bit ropey for client-facing systems (use MSIs) • Split the codebase along domain boundaries • Detect configuration drift • Add metrics and logging somehow
32. CDwithWindows.net Recommendations
33. CDwithWindows.net Recommendations • Focus on continual flow of changes • Collect effective metrics from live systems • Branch code with caution!
34. CDwithWindows.net
35. CDwithWindows.net Recommendations • Use Git (not Svn / TFVC) • Immutable infra with Windows 40GB VMs is difficult (impossible?)
36. CDwithWindows.net
37. CDwithWindows.net Recommendations • Use NuGet for internal dependencies • Use a proper artifact repository: Artifactory, Nexus, … • Solution (.sln) / Project (.csproj) structure affects buildability - restructure
38. CDwithWindows.net
39. CDwithWindows.net Recommendations • Automate DB changes: Redgate / Fluent / Flyway … • DB ownership gets tricky: Dev vs DBA • Patch mgt: test in upstream envs
40. CDwithWindows.net
41. CDwithWindows.net Recommendations • Devolved AD administration with automated domain join/leave • Detect config drift: UpGuard / ... • Make friends with Linux for best tooling!
