This document summarizes Bob Strecansky's presentation on scaling SRE. The presentation covers both the technical and people sides of scaling SRE. On the technical side, it discusses how a company's first SREs should establish monitoring of the four golden signals (latency, traffic, errors, saturation) and implement logging, metrics, profiling and distributed tracing. It also discusses SLIs, SLOs and SLAs. On the people side, it addresses prioritizing work, engaging and disengaging staff, facilitating change and helping teams grow while also reacting to incidents.
