Continuous Delivery - Making it work with Windows and .NET

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’.

37. 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
38. CDwithWindows.net Recommendations
39. CDwithWindows.net Recommendations Focus on continual flow of changes Collect effective metrics from live systems Branch code with caution!
40. CDwithWindows.net
41. CDwithWindows.net Recommendations Use Git (not Svn / TFS) Immutable infra with Windows 40GB VMs is difficult (impossible?)
42. CDwithWindows.net
43. CDwithWindows.net Recommendations Use NuGet for internal dependencies Use a proper artifact repository: Artifactory, Nexus, … Solution (.sln) / Project (.csproj) structure affects buildability - restructure
44. CDwithWindows.net
45. CDwithWindows.net Recommendations Automate DB changes: Redgate / Fluent / Flyway … DB ownership gets tricky: Dev vs DBA Patch mgt: test in upstream envs
46. CDwithWindows.net
47. CDwithWindows.net Recommendations Devolved AD administration with automated domain join/leave Detect config drift: UpGuard / ... Make friends with Linux for best tooling!
