The following is a video of me giving this presentation: https://youtu.be/nsxrKPthl8E
DevOps is a means to end, but what is that end and what is the path?
2. Agile
1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan
1.A reaction to the same failures, over and over again. It is too dynamic, so no one process will work.
2.Cargo Cult – What an Agile Cargo Cult is, and how the Corporation is also a cargo cult
3.A silver bullet, a tool of control, and what to blame when it all goes wrong.
4.How we killed Agile by throwing the manifesto out the window, enabling certificate mills, and selling it as a product
5.Just let the team run like they want, and don’t call it Agile (a loaded term)
1.Unit Testing – Isolated versus Social
2.Service Testing – Integration versus Contract
3.UI Testing – How you can do it without being E2E. Acceptance testing limitations
4.How E2E testing is not possible in modern distributed systems – The SMS problem
5.Exploratory Testing – Using humans for what they are good at
1.Remember the Testing Pyramid – This is where you start realizing that things like Agile and Test automation are prerequisites
2.CI is three things – You can’t do thing without test automation
3.CD requires CI – Otherwise you are just breaking stuff faster
4.Continuous Deployment is possible – You just need good people and automation. Places go 100+ times a day, easy.
1.Source control is fundamental to software as config as code and code is code
2.SCM has changed greatly, and Git dominates the market at 73% as of 2022
3.Along of companies did a lift and shift onto Git, not taking into account major conceptual improvements
4.Cloning, Commits, Pushes, Branching, Tagging, Pull Requests
5.Branching strategy tends to be the number 1 thing impeding CI, and it is always unnecessary
1.The walls we built to make software
2.The attempt to quantify everything into a single process with roles
3.Decisions with no context, the blame game, turn the ship around
4.The cargo cult of corporations
5.DevOps as more of a culture than a process
