Scientific Process in Microservices and DevOps: Enhancing Development Practices
Explore the intersection of scientific processes with Microservices, DevOps, and Container Technology, as presented by Henrik Børbak Christensen. Learn how observation, hypothesis, experiment, and conclusion play a crucial role in refining practices and achieving reproducibility in software development. Embrace detailed record-keeping, guided by examples and guides, to optimize workflow efficiency and avoid costly errors. Test-Driven Development is likened to a natural science process, emphasizing the importance of methodical approaches in software development. Apply science to your work for better outcomes!

Microservices and DevOps DevOps and Container Technology Scientific Process Henrik B rbak Christensen
Scientific Process The only difference between screwing around and science is writing it down! - Andy Savage / MythBusters Apply Science in your work! (Most likely, you will need what you ve written down at the final individual exam) Henrik B rbak Christensen CS@AU 2
Scientific Process Observation How does system behave? Hypothesis Improve/correct by doing X Experiment Execute Conclusion Hypothesis is Observation Detailed Record Keeping Experiment Hypothesis TRUE: FALSE: Alt. Hypo. Finding Theory Refine Hypo. Detailed Record Keeping! To avoid getting lost! To track progress! To be reproducible! CS@AU Henrik B rbak Christensen 3
Example: Experiments Keep the diary/logbook/journal at hand! Make notes! Goal, hypothesis, experiment, conclude [loop] CS@AU Henrik B rbak Christensen 4
Example: Guides (Conclusions) Update the Cave Subscription service (2016 version) All that Gradle stuff CS@AU Henrik B rbak Christensen 5
A note Detailed record keeping saves your sanity! Christmas vacation: MQ update lead to total reinstall Guides helped me reestablish full working environment Extending Mongo DB disks Involves repeating 10-15 steps in three differently configured machines And a wrong step may crash 6 TB data CS@AU Henrik B rbak Christensen 6
Test-Driven-Development Is basically a natural science process Reed, 2019 CS@AU Henrik B rbak Christensen 7
