Intro to Scaling Prometheus with Cortex

summary
Cortex provides a horizontally scalable, highly available Prometheus-compatible TSDB that accepts Prometheus remote_write traffic, shards via a distributed hash table, replicates data for fault tolerance, and offloads long-term blocks to object stores (S3). It claims to handle hundreds of millions of series and enforces multi-tenancy and QoS so teams don’t starve each other. The demo wires three Prometheus instances into a three-node cluster, pushes metrics, shows global aggregates in Grafana, and the setup works end-to-end.
