SLOs can be a great way for DevOps and infrastructure teams to use data and performance expectations to make decisions, such as whether to release and where engineers should focus their time. In this example, “Reverse proxy” and “Front-end server” are clearly in the critical path. SLOs aid decision making. SLOs promote automation.
