Give stateful workloads fast, automatically-managed local storage on Kubernetes — tiered, QoS-controlled, capacity-aware — with Carina.

Welcome to Carina: Cloud-Native Local Storage.

A practical, in-depth guide to Carina, the cloud-native local storage system for Kubernetes. Learn how Carina delivers high-performance local storage to stateful workloads: the local storage problem (network vs local), the three-component architecture (carina-node, carina-controller, carina-scheduler), automatic disk management with LVM and device groups, dynamic volume provisioning and topology, capacity-aware scheduling, performance (tiering, I/O QoS, RAID), reliability (failover and app-level replication), and operating Carina at scale.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.
