What is KubeBlocks

KubeBlocks is an open-source Kubernetes operator that manages relational, NoSQL, vector, and streaming databases on the public cloud or on-premise. It is designed for production purposes, providing reliable, performant, observable, and cost-effective data infrastructure for most scenarios. The name KubeBlocks is inspired by Kubernetes and LEGO blocks, signifying that building data infrastructure on Kubernetes can be both productive and enjoyable, like playing with construction toys.

Why you need KubeBlocks

When adopting a multi-cloud or hybrid cloud strategy, it is essential to prioritize application portability and use software or services that offer consistent functionality across different infrastructures. Kubernetes has helped in achieving this goal to some extent, and KubeBlocks can further enhance the experience. KubeBlocks integrates popular database engines and provides rich management functions, along with declarative APIs, on various infrastructures. Furthermore, KubeBlocks offers the following benefits:

  • Performance

    You do not have to learn database tuning. KubeBlocks can leverage storage and computing resources to achieve optimal database performance.

  • Reliability

    You do not need to worry about data loss or service outages. KubeBlocks provides fault tolerance at the node or availability zone levels, which maximizes database reliability.

  • Observability

    You can track new metrics under one roof. KubeBlocks integrates observability platforms such as Prometheus stack, AWS AMP, Aliyun ARMS, etc., and provides beautiful templates with insights.

  • Extensibility

    You can integrate and use new database engines with ease. KubeBlocks provides a good abstraction of the database control plane, allowing for efficient support of new database engines with a consistent user experience.
