My Highlights from Continuous Delivery and DevOps Conference 2015
Posted by Jakub Holý on April 30, 2015
The first Continuous Delivery and DevOps Conference in Oslo is over. It was nice to see so many people interested in the topic. I would have preferred more practical talks of the “how we did it” type over the “why” type but it was OK, though next year I would prefer flatMap. Here are my highlights:
- Atmel is using a physical robot to plug and connect a particular configuration of circuit boards to test; your automated testing challenges cannot be greater than theirs!
- Continuous Delivery decreases the risk of outage and time-to-recovery while enabling faster innovation, correlates with higher profits; No efficiency improvement will outperform cycle time reduction
- Estimation pathologies; focus on value rather than costs
- Stop talking about requirements, they are fake; they’re just beliefs about what may add value to customers. Use hypothesis instead!
- Cisco: Most of the tools increasing productivity (and some innovation) were produced by engineers in their “spare” time; slack time is thus crucial
- How does Cisco grow professionalism : optimise for the 10% best, not the 10% weakest developers; slack time; make everything visible; encourage code reviews but avoid making them mandatory; see the slide
- CALMS: Culture, Automation, Lean, Measurement, Sharing. The pillars of devOps
- Cisco invested a lot in crafting their build system, tailored test frameworks, and emulators to be able to get quick and quality feedback – because it pays off
- “Make you own build system” says @olvemaudal at @CoDeOSL. IME this is inevitable for non-trivial projects, and a good investment.
- Unleash: Feature Toggles server and Java/Node client by FINN.no
- “They asked for a report while they actually need just a list of data, the result of a simple SQL query; have we listened to them, we would have wasted hours creating a report in the report framework with logos and all the crap.”
