KubeBlocks Database PaaS

KubeBlocks is an open-source Kubernetes-native database management platform that helps teams run relational, NoSQL, vector, and streaming databases on Kubernetes with production-grade reliability. Developed by ApeCloud (founded by former PingCAP engineers) and now a CNCF Sandbox project, KubeBlocks has over 9,000 stars as of 2026. The name combines Kubernetes and building blocks, reflecting its mission to provide a composable approach to managing databases. Key features include: multi-engine support (managing over 30 database engines including MySQL, PostgreSQL, Redis, MongoDB, Kafka, ClickHouse, OpenSearch, Qdrant, Milvus, Elasticsearch, and NebulaGraph through a unified API), declarative management (defining clusters via Kubernetes CRDs with automated provisioning, scaling, and lifecycle management), high availability (automatic failover, switchover, and recovery for primary-replica topologies), backup and restore (scheduled and on-demand backups to S3-compatible storage with point-in-time recovery), monitoring (Prometheus integration with database-specific metrics and health monitoring), storage management (dynamic volume provisioning and expansion), vertical and horizontal scaling (CPU, memory, and replica scaling without downtime), rolling updates and database version upgrades, migration tools (importing data from external databases), multi-cloud (AWS EKS, Azure AKS, GCP GKE, Alibaba ACK, and self-managed clusters), and ops-free database management (abstracting complex operations behind simple Kubernetes manifests).
