How Queueing Theory Makes Systems Reliable

One2N

Team

Learn how SREs use queueing theory to explain why 70 percent utilisation feels calm, 90 percent feels cursed, and how the same math helps you choose headroom, tame retries, and protect your error budget before incidents hit.

Percentiles in SRE: Why averages lie about latency

One2N

Team

See why SREs stop trusting average latency and switch to percentiles, with clear examples of p50, p95, p99, how they expose tail pain for real users, and how to pick the right percentiles for your system.

One2N

Team

This guide explains how latency, throughput, and utilisation really interact, why running at 90 percent capacity quietly wrecks your SLOs, and how to pick safe headroom so your system can survive real-world traffic spikes without falling over.
