A Blueprint for Multi Layer Service Level Management

This article highlights the “Observability Gap” – the disconnect between healthy infrastructure metrics and poor user experience, often caused by measuring components in isolation. To bridge this gap, the author advocates for a Service Level Management (SLM) Reference Architecture, focusing on measuring user experience and defining clear Service Level Indicators (SLOs) at every layer of the application stack – from user interface to infrastructure. By focusing on what users actually experience and tying technical health to business outcomes, organizations can proactively identify and address issues before they impact customers and generate support tickets.
