Cortex consists of multiple horizontally scalable microservices. Each microservice uses the most appropriate technique for horizontal scaling; most are stateless and can handle requests for any users while some (namely the ingesters) are semi-stateful and depend on consistent hashing. This document provides a basic overview of Cortex’s architecture. The following diagram does not include all the Cortex services, but does represent a typical deployment topology. The role of Prometheus Promet...
