I’ve been using deployment pipelines since 2011 starting with GoCD and then other tools. A few months ago, I joined DevOps experts Helen Beal of Ranger4, and Sam Fell & Anders Wallgren of Electric Cloud to discuss deployment pipelines for modern software delivery as part of the Continuous Discussions (#c9d9) series (episode 88).
(YouTube video segments below)
- The concept of the deployment pipeline was defined and popularised by the 2010 book Continuous Delivery by Jez Humble and Dave Farley.
- Deployment pipelines are a really key concept for modern software delivery – all changes flow through the deployment pipeline.
- The fast feedback from deployment pipelines can and should completely change the way we approach software. We can expect rapid feedback on changes which encourages us to make smaller, more frequent code check-ins.
- Value Stream Mapping can be a powerful way to uncover large wait times in the delivery flow.
- A “walking skeleton” deployment pipelines – essentially modelling the current approval/change flow but with empty stages in a tool – helps us to sense-check the current state: “do we really need an approval gate at this point?”

Back in 2010 when Jez Humble and Dave Farley wrote their ground-breaking book Continuous Delivery, the Windows and .NET platforms lagged behind the Linux/Mac world in terms of automation capability. That is no longer the case – every core feature in Windows and .NET now has a PowerShell API and all the core tooling needed for Continuous Delivery – package management, artifact repositories, build servers, deployment pipelines tools, infrastructure automation, monitoring,and logging – are all now available natively on Windows/.NET.
Chris O’Dell (@ChrisAnnODell) and I decided we should explain how to make Continuous Delivery work with Windows and .NET, and thanks to the great editorial team at O’Reilly, we’ve published a short eBook:
The dedicated book website is at CDwithWindows.net and O’Reilly have published the first chapter of the book online as an article: Introduction to Continuous Delivery with Windows. We’d love your feedback: firstname.lastname@example.org
UPDATE: we’ll be at both PIPELINE Conference (March 23 2016) and WinOps Conference (May 24 2016) with printed copies of the book.
Note: we began writing the book in August 2015, and it’s astonishing (and exciting!) how much has changed in the 8 months since then, with Windows Nano, Azure and Windows support for Docker and containers, .NET Core, SQL Server on Linux, and even SSH for Windows. These and more recent developments do not feature in the book – perhaps we’ll do an updated version soon.
