 ## What is KubeBlocks
 
-KubeBlocks is an open source system software that runs and manages data infrastructure on Kubernetes. It could manage various data systems, including RDBMSs (MySQL, PostgreSQL), Caches(Redis), NoSQLs (MongoDB), MQs(Kafka, Pulsar), and vector databases(Milvus, Qdrant, Weaviate), and the community is actively integrating more types of data systems into KuberBlocks. KubeBlocks helps developers, SREs, and platform engineers deploy and maintain dedicated DBPaaS in the enterprise, and supports a variety of public clouds and on-premise environments.

-KubeBlocks is designed for production purposes, providing secure, cost-effective, high-available and extensive DBPaaS for enterprise. The name KubeBlocks is inspired by Kubernetes and LEGO blocks, signifying that integrating data infrastructure on K8s can be both productive and enjoyable, like playing with construction toys. The core of KubeBlocks is a K8s operator, which defines a set of CRDs to abstract the common attributes of various data systems, thereby supporting the rapid integration of a new data system into KubeBlocks while keeping the same operating experience and expected behaviors.

 * Cost-effective
 
-  KubeBlocks optimizes the kernel and parameters of MySQL and PostgreSQL databases for containerized and cloud environments, and its performance exceeds that of RDS with the same hardware (see our blogs for details).

 * Reliability
 
   KubeBlocks supports high-availability cluster configurations for multiple database engines, and supports Raft replication cluster for MySQL to achieve enhanced availability with durability guarantees.
 
 * Observability
 
-  KubeBlocks collects monitoring metrics from rich data sources, integrates with the Prometheus stack, and provides insightful Grafana templates. In addition, troubleshooting tools such as slow logs are also provided.
