Operational Excellence

Failure to meet operational excellence

One would think to rotate their certificates months prior to expiration. Or even the bare minimum

Key takeaways
  • Operational excellence is built on blameless post-mortems and relentless root cause elimination.
  • Systems fail in complex ways; resilience is how quickly they detect and self-correct.
  • Reliability and security are two sides of the same engineering discipline.

One would think to rotate their certificates months prior to expiration. Or even the bare minimum “setting up a calendar event.”
