Thanos Long Storage
Thanos extends Prometheus with long-term storage (months/years instead of weeks). Stores metrics in object storage (S3, GCS), enables global querying across clusters, and provides cost-effective archival. Used by DevOps and SRE teams. Salary band: 105–165k USD. Time to learn: 4–6 weeks. Adjacent to Prometheus, Kubernetes, and observability. Essential for large-scale monitoring.
What is Thanos Long Storage
Thanos is an open-source CNCF project extending Prometheus to enable long-term metrics storage and global querying. It offloads older metrics to object storage (S3, GCS, Azure Blob), allowing retention of years of data at minimal cost. Thanos provides a unified query interface across multiple Prometheus instances and archived data, enabling global monitoring dashboards. Thanos is a common architecture choice for organizations scaling beyond single Prometheus instances. It decouples storage from compute and enables efficient long-term retention.
