The document is a humorous take on DevOps practices, drawing inspiration from 'The Rocky Horror Picture Show' to illustrate challenges and solutions in software deployment. It highlights the importance of automated CI/CD, load testing, contract testing, and chaos testing in maintaining uptime and performance during high demand. The narrative emphasizes the need for proactive measures to ensure system reliability and proper resource management in software development.

home of happiness…
✓automated CI/CD pipelines
✓swell coverage with unit tests
✓feature branches deploy to staging envs
✓QA tests and validates the system
ready for production…

6. An Evenings affair…
✓scale up more pods
✓“overprovision” to maintain uptime
✓developers say it’s not the code
✓postmortems are written
what is to become of Brad and Janet?
you’d better wise up Janet Weiss!

8. Back in the Lab…
✓unit and E2E tests alone were not enough
✓latencies will compound with high demand
✓poor resource handling appears at scale
✓didn’t know when something was wrong

✓add load testing within build pipeline
- tools like k6, JMeter, Gatling
✓establish benchmarks and objectives
✓de

✓add contract testing to verify APIs
- tools like k6 or Pact
✓assures backward compatibility
✓consumer-driven contracts

12. Shifting Left…
✓add chaos testing
- tools like k6, Steadybit, or Gremlin
✓determine behavior in crisis
✓incorporate fallbacks based on failure
say `hello` to oblivion!
oooh…Rocky!
