About:
Cortex is a horizontally scalable, multi-tenant Prometheus backend. It aggregates metrics from multiple Prometheus instances, providing long-term storage and querying capabilities. The tool enables organizations to centralize observability data while maintaining strict tenant isolation.

Key Features:

Horizontal scalability for massive metric volumes
Multi-tenancy with strict isolation
Long-term storage with downsampling
Prometheus-compatible query API
S3/GCS/Cassandra storage backends

Use Cases:

Centralized metric storage for large organizations
Long-term retention of Prometheus data
Multi-tenant observability platforms
Scaling Prometheus beyond single-instance limits

Alternatives:

Thanos – Similar scalability features but different architectural approach to sidecars and compaction
M3DB – Provides storage but less focus on multi-tenancy and Prometheus compatibility
