Overview In modern microservice architectures, a seemingly simple user request may traverse dozens of service nodes. When an incident occurs, the first question an SRE engineer faces is often not “how to fix it” but “what is the scope of impact.” Without a fast answer to this question, incident recovery gets bogged down in endless investigation. Service Dependency Maps and Failure Domain Analysis are the engineering methodologies that address this problem....
