The Business Case for Observability and Site Reliability Engineering

Throughout this series, we’ve been exploring the interplay between the discipline of Site Reliability Engineering (SRE), the role of the Site Reliability Engineer (also SRE), and observability. We examined the meaning of adopting an SRE discipline, how observability differs from monitoring, and the role of...

SREs, Observability, and Automation

In the first article in this series I explained the fundamental tradeoff of site reliability engineering (SRE, which also stands for site reliability engineer) – the tradeoff between reliability on the one hand and deployment velocity and cost on the other. My colleague Charles Araujo, in...

Observability and SaaS Providers

What is Observability? Observability is a characteristic of systems in that they are observable. Its roots are in mechanical engineering. It’s a measure of how well the internal states of a system can be inferred from knowledge of its external outputs. In software, which is largely invisible,...

Observability vs. Monitoring

Back in the old days of monolithic architecture, IT teams could rely on legacy monitoring tools to get visibility into apps, identify service-impacting incidents and make the necessary fixes. But as the industry moved to distributed serverless, cloud-native architectures, systems grew increasingly complex, layered and,...
