DevOps Notes and Resources

DevOps Resources

• DevOpsDays: Conferences arguably were the structures that germanated the movement's accelerated adoption and cloud. The conferences help ignite the DevOps cultural movement/moment.

Background

• Germinated as conversations around Agile System Admin practices: @littleidea, @patrickdebois
• MeetUp organized by Patrick Debois in Ghent, Belgium October 2009 Decade Anniversary

Meta Resources: Talks and Presentations

• John Willis aka @Botchagalupe the meta-gist motherlode of DevOps Goodness
• The tremendous influence of Dr. Edwards Deming. Relations to DevOps See Profound site Podcast the SoPK (System of Profound Knowledge)

CA(L)MS

• CAMS: Culture, Automation, Measurement, Sharing _ attribution John Willis/Damon Edwards on DevOps Cafe podcast The L for CA(L)Ms came after the suggestion of Lean by Jez Humble i(author os Lean Enterprise) and Daemon Edwards

• Culture: Part1 Part 2

• Automation

• Measurement

• Sharing

• Netflix Culture Deck and Patty McCord TED TALK

The Three Ways

• Gene Kim's explaination
• First Way (Flow): Work always flows in one direction – downstream Dev Ops ala ‘wall of confusion’ Shafer/Thompson
• Second Way (Feedback): Create, shorten and amplify feedback loops (right to left).
• Third Way (Continuous experimentation): Creating a culture that fosters two things: continual experimentation, taking risks and learning from failure; and understanding that repetition and practice is the prerequisite to mastery.

How do these apply to every project/product worked on?

SRE

• What is the role of Site Reliability Engineer? SRE Book and SRE Workbook. How SRE relates to DevOps

Configuration Management

• Mark Burgess CFEngine, Promise Theory and how the field of physics informs IT. Burgess pretty much invented modern config management space. By extension heavily influenced Adam Jacob @OPsCode/Chef The first time I heard Adam Jacob speak at Velocity 2011, I was struck by how open and generative giving attribution to a hero and influence can be. Mark Burgess, though perhaps less known has had a great influence on the area.

Config Management Prime-Movers

• Luke Kaines (Puppet)
• Adam Jacob (Chef)
• Michael DeHann (Ansible)
• Mitchell Hashimoto and Armon Dadgar (Terraform)
• Jeff Snover (PowerShell)

Kim and ITRevolution

• Gene Kim (Visible Ops, ITRevolution, DOES) @realgenekim When IT Fails

Adrian Cockroft

• One of my favorite influences in the movement (Sun/Netflix/AWS) Investigate Chaos Engineering and more DevSusOps and the Sustainability tier added to the Well Architected Framework.
• Check his talks and Chaos Eingineering and book recommendations.

Podcasts:

• Cloud Cafe
• DevOps Cafe
• Arrested Devops
• The Ship Show
• Software Defined Talk

DORA, Dr. Foresgren, Jez Humble and Accelerate

• DORA DevOps Data singularity Dr. Nicole Forsgren @nicolefv
• Accelerate
• Jez Humble Continuous Integration/Continuous Delivery (also DORA and Accelerate) Humble/Farley

Extremely influencial as a measurement. Currently a measure for an orgs capabilities. There were 5 metrics with operational excellence being one, however this metric seems to have been scaled back and disappeared. Operational Excellence is key to sucess so there is more for me to understand in these measurements.

The Five Key DORA Metrics

• Deployment Frequency (the frequency at which new releases go to production)
• Lead Time For Changes (the time until a commit goes to production)
• Mean Time to Restore (the time it takes to resolve a service impairment in production)
• Change Failure Rate (the ratio of deployments to production that leads to errors and successful deployments).
• Operational Excellence / Resilience (added 2019)

DORA and the State of DevOps Report

• 2023

DevSecOps

• James Wickett DryRun Security
• Rudgged DevOps Justin Cormack IAmTheCalvary

In the so-called 'DevOps transformation', InfoSec wasn't invited to the party. DevSecOps seeks to fix that and shift security left and embrace more modern patterns of GRC (governance, risk and complience).

Strategy and Wardley

• Simon Wardley: Wardley Mapping Wardley pioneered the use of mapping as a strategic tool. It can be used for personal goals and strategy and organizational transformation. It's like he can tell the future and often does. Worth a follow @swardley and Medium

Policy as Code

Emergent with automation and builds pipelines is the notion of declaritive code that enforces policies. While not new these methods of

Goldratt

• Goldratt the Theory of Constraints (TOC). Also see The Goal and The Phoenix Project (Gene Kim)

The Five Ideals

• Gene Kim's explaination
• Locality and Simplicity (Sprouter @ Etsy) Synchronize and coordonate team's work. The primacy of Architecture on productivity.
• Focus Flow and Joy
• Improvement of Daily Work
• Psycological Safety
• Customer Focus

Seminal Videos

These are just some of the videos I can recall creating an aha moment. There are many more in DevOps Enterprise Summit and YouTube.

Ben Rockwood: 10 Deploys a Day

This was one of the earliest videos I can remember about transformation as intention and practice The DevOps Transformation

10 Deploys A Day

• John Allspaw and Paul Hammond at Flickr 10+ deploys a day (Velocity 2009)

Andrew Clay Shafer

• There is No Talent Shortage

Seminal Texts

The Lean Startup Steven Blank's book The Four Steps to Ephiphany heavily influenced Eric Reis as a student at Stanford.
