This tutorial explains how to connect Kubernetes to external storage via the Container Storage Interface, covering local mode storage setup, configuration steps, verification, and best‑practice tips for reliable, persistent data management in cloud‑native environments.
Prometheus, a leading monitoring system, can achieve high availability through several common architectures—including dual-node with external storage, federated mode with external storage, and multi-node clusters combined with Thanos and object storage—each offering data persistence and load distribution to enhance system stability and performance.
PostgreSQL's TOAST mechanism automatically compresses and, when necessary, moves oversized column values to an external toast table, using four storage strategies (plain, extended, external, main) that dictate compression and externalization behavior, with data exceeding roughly 2 KB triggering external storage regardless of strategy.
