DESCRIPTION
Alex Ewerlöf shares his journey from product engineering to reliability engineering and discusses the practical challenges of implementing Google's SRE practices in real-world companies.

He emphasizes the significant gap between Google's idealized SRE approach — which he links to "a fantastic chef's recipe for Michelin-starred restaurants" — and the reality most companies face with limited resources and infrastructure. The discussion covers key topics including the evolution from traditional operations to where engineers own their code in production, the critical importance of choosing SLIs that align with business impact, and how SLOs help set expectations and help the service consumers prepare non-functional requirements.

Alex coined the law of 10x per 9 highlighting that reliability isn't free and requires careful cost-benefit analysis.
