SLAs, SLOs, and SLIs: Demystifying SRE
– Room 7
Foredragsholder
Om sesjonen
Reliability is not an accident — it's math. This session builds a clear, working understanding of SLIs, SLOs, and SLAs from first principles, starting with availability math: what the nines actually mean, how multi-service architectures compound failure, and what it realistically takes to move from two nines to four. We define exactly what to measure and why — the difference between infrastructure signals and user-experience signals, and how to derive SLIs that reflect real outcomes rather than server health. The centrepiece is the error budget: what it is, how it's calculated, and how it changes the way teams make decisions. Error budgets turn reliability from a feelings argument into a shared engineering constraint that drives development velocity, architecture choices, and operational maturity at the same time. We close with the SRE maturity arc — the practices, not the tools, that separate reactive firefighting from proactive reliability engineering. You'll leave with a mental model your whole team can use, from developer to architect to ops lead.
