Site Reliability Engineering in Derry

Running Derry organisations' systems to a reliability target chosen deliberately. The idea that changes the conversation is that perfect availability is the wrong goal — each additional decimal place costs disproportionately more, and a target set above what customers actually need buys expense rather than satisfaction.

Why this comes up

The problem

Reliability is discussed only after an outage, nobody has agreed what good looks like, and every incident produces process that slows the next release.

What you get

What we deliver

  • Objectives agreed for the things users notice, expressed in measurable terms
  • An error budget defined, giving a shared basis for release-versus-stability decisions
  • Alerting tied to those objectives rather than to every technical anomaly
  • On-call arranged so it is sustainable rather than dependent on two people
  • Blameless incident review, since the alternative suppresses the information you need
  • Toil identified and reduced, as manual operational work crowds out improvement

Site Reliability Engineering in Derry — common questions

Why not aim for perfect uptime?
Because the cost rises steeply and the benefit does not. Users rarely distinguish between very high availability and near-perfect, while the difference in engineering effort is substantial. Choosing a target consciously is what lets you spend the remaining effort on things customers value.
What is an error budget for?
Settling an argument that otherwise recurs monthly. If the agreed target allows a certain amount of unreliability and you are within it, releases continue; if you have exhausted it, stability takes priority. It converts a matter of opinion into a number both sides accepted in advance.
How should alerting be designed?
Around user impact. Alerting on every anomaly produces a team that ignores alerts, which is worse than fewer of them. If nobody would act at three in the morning, it is not an alert — it belongs on a dashboard or in a report.
Why blameless review?
Because people who expect blame withhold detail, and the detail is the point. Reviews that find which individual made the error produce compliant silence and repeated incidents; reviews asking why the system allowed the error produce changes that prevent recurrence.
