This video discusses how performance analytics can be used to improve the reliability of services. It explains that the three critical components of reliability are availability, performance, and correctness, and that there is a lot of ambiguity in how these factors are measured. The video discusses how slos can be helpful in identifying and quantifying reliability issues, but notes that they have limitations in capturing the full richness of system failures.
This talk provides an overview of how performance analytics can be used to answer questions about how a system is performing, how it changes over time, and how reliable it is. The speaker also mentions that performance data is often more useful than availability data, and that there are many more invariants that can be validated.
