Ceph CSI for Kubernetes
Operate Kubernetes with production-ready storage.
CLYSO integrates Ceph with Kubernetes via the Container Storage Interface (CSI), enabling highly available persistent storage while avoiding vendor lock-in.
Persistent Storage Is Where Kubernetes Gets Serious
Kubernetes has transformed application deployment. When workloads depend on persistent data, however, requirements for reliability, scalability, and performance increase dramatically.
Storage must integrate seamlessly, scale predictably, and remain resilient under production conditions — without adding operational complexity.
Meeting these demands requires more than storage connectivity. It requires a platform designed for stateful workloads.
Production-Ready Storage for Kubernetes — with Ceph and CSI
Ceph CSI is a community-driven project that seamlessly integrates Ceph with Kubernetes via the Container Storage Interface (CSI). Built on open standards, it provides a flexible storage architecture without vendor lock-in.
CLYSO brings deep expertise across the entire stack — from Kubernetes to Ceph CSI to the underlying Ceph platform — supporting organizations in architecting, implementing, and operating production-grade storage environments.
High-Availability Architecture
Built-in redundancy protects data and ensures continuous operation.
Seamless Scalability
Expand capacity without disrupting running applications.
Open Architecture
Built on open standards — with no vendor lock-in.

Frequently Asked Questions
These are the questions organizations most often ask when evaluating Ceph CSI for production Kubernetes environments.
Is Ceph CSI production-ready?
Yes. Ceph CSI is widely established in production Kubernetes environments worldwide. Combined with CLYSO’s architecture and operational expertise, it provides a reliable foundation for persistent storage.
Should I use RBD or CephFS?
It depends on your workload requirements.
RADOS Block Device (RBD) is typically preferred for high-performance applications such as databases, while CephFS is well suited for workloads that require shared file access across multiple containers.
CLYSO helps organizations select the right storage strategy based on architecture and performance requirements.
Do I need Ceph CSI, Rook, or both?
Ceph CSI and Rook serve different roles within a Kubernetes storage architecture.
Ceph CSI provides the standardized interface that allows workloads to dynamically consume persistent storage. Rook focuses on automating the deployment, scaling, and lifecycle management of the underlying Ceph cluster.
Together, they enable a fully integrated, cloud-native storage architecture that is ready for production environments.
Does Ceph CSI create vendor lock-in?
No. Ceph CSI is built on open standards and integrates seamlessly with the Kubernetes ecosystem. Organizations retain full control over their infrastructure while avoiding dependency on proprietary storage platforms.
This open approach supports long-term flexibility and infrastructure independence.
Why does data locality matter in Kubernetes storage?
Data locality plays a critical role in achieving predictable performance for stateful workloads. When applications can access storage resources with minimal network distance, latency decreases and throughput improves. Ceph is designed to intelligently distribute data across the cluster while maintaining high availability. Combined with CSI, this architecture enables Kubernetes platforms to balance performance, resilience, and scalability — without binding workloads to specific nodes.
