Modern Systems Development talk for TechStars Cloud 2015
- 1. Modern Systems Development Creating Services at Scale
- 2. Manifesto for Agile Software Development We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan That is, while there is value in the items on the right, we value the items on the left more.
- 3. Agility Cooperation Awareness Microservices
- 4. Why does any of this matter?
- 5. Rise of Determinism Newtons Principia Laws of physics are universal The world is mechanistic, material and mathematical Laplaces Demon Careful measurement of current conditions Understanding of the laws that drive the world Sufficient computing power to find the truth Basis for much of science for the next 400 years
- 6. The Logistic Equation f(xn+1)=rxn(1-xn) simple formula for estimating population r is the rate of population growth xn is the current population
- 7. First Look
- 11. Chaos
- 13. Butterfly Effect xpurple = .2 xgreen = .2000000001
- 14. Implications Laplaces Demon may still be theoretically possible Careful measurement of current conditions Understanding of the laws that drive the world Sufficient computing power to find the truth However it could also be risky to bet on it Chaotic determinism Sensitive dependence on measurements Be ready for the unexpected The fastest to adapt usually wins. Speed matters.
- 17. What to do?
- 19. TRUST
- 20. Conflict without trust is politics. Conflict with trust is a search for the truth. Patrick Lencioni
- 21. CONTRIBUTION
- 26. Barriers to Cooperation Dont know what to do (share knowledge) Dont know how to do it (share culture) Cant gauge progress (measure it) Cant see who is responsible (automate it) - Theory of Cooperation, John Willis and Damon Edwards
- 27. Theory of Cooperation Culture (of communication and discipline) Automation (superhuman scale and speed) Measurement (bringing verification and certainty) Sharing (to enable a rapidly growing community to the bar quickly) - Theory of Cooperation, John Willis and Damon Edwards
- 28. Communication Single ticket queue Always on chat room Daily stand ups Semi-weekly planning Every six month hack week
- 29. Automation and Architecture CI/CD Provisioning Containers Microservices Scale out Backwards compatibility
- 30. Measure It Log Aggregation (Logstash, Loggly, Apache Kafka) Metrics (Graphite, Graphana) Monitoring (NewRelic, DataDog, Nagios) Alerting (PagerDuty)
- 31. Summary Building modern web services requires new approaches Speed. Speed. Speed. Constant evaluation from diverse inputs Always plan for change Culture must intentionally be built to support these goals
- 32. Final Thoughts Dont try and do all the things Do something now vs. plan for perfect later Take time thinking about the ideal Take pragmatic steps everyday that are on the path
