When running a microservice-based architecture, traffic flows from the front-end, passes through multiple microservices, and eventually receives the final response from the back-end. Kubernetes is a container orchestrating service that helps us run and manage these numerous microservices, including multiple copies of them if necessary.
During the lifecycle of a request, if it fails at a specific microservice while moving from one service to another, pinpointing the exact point of failure becomes challenging. Observability is a paradigm that allows us to understand the system end-to-end. It provides insights into the “what,” “where,” and “why” of any event within the system, and how it may impact application performance.
