Defining SLOs: A Practical Guide

SLOs often seem simple in theory, but tend to get difficult when actually implementing them, as the reality if often not by the textbook. SLOs are an invaluable tool for both engineers as well as management to consistently communicate reliability with data. Defining bad SLOs can also be harmful, so it’s important to keep various caveats in mind. Not only are SLOs about data, it is equally important to clarify and evangelize expectations of SLOs within an organization. Frederic and Matthias have many years of experience of defining SLOs for many services and components. Together they will demonstrate real life examples of choosing, measuring, alerting and reporting SLOs based on Prometheus metrics. Join this talk to learn how to implement SLOs successfully using data you most likely already have.
