In the cloud-native era, a growing number of enterprises are leveraging Kubernetes to host stateful workloads like databases and message-oriented middleware. These applications have demanding needs for data storage, performance, scalability, and rapid deployment. As a result, enterprises often face the challenge of finding the most suitable storage solution on Kubernetes.
To assist users in product selection, in this article, we will evaluate mainstream Kubernetes-native storage, including Longhorn, Rook, OpenEBS, Portworx, and IOMesh, and make a comprehensive comparison of their capabilities and performance.
Gartner outlines five features for storage providing cloud-native data services in the report How Do I Approach Storage Selection and Implementation for Containers and Kubernetes Deployments:
Based on these criteria, we compare Longhorn, Rook, OpenEBS, Portworx, and IOMesh through the lenses of source openness, technical support, storage architecture, advanced data services, Kubernetes integration, and more.
Alongside this comparison, users need to pay particular attention to the following capabilities if they:
Performance is a key indicator of a storage system’s capability in supporting core business applications. We conducted performance tests on IOMesh, Longhorn, Portworx, and OpenEBS* in MySQL and PostgreSQL database scenarios. Using the sysbench-tpcc tool, we simulated production workloads to evaluate the responsiveness and performance of these storage solutions.
The graph below shows how the 4 storage systems performed in the two database scenarios. Performance was evaluated in TPS, QPS, and p95 latency.
In terms of overall I/O performance and stability, IOMesh emerged as the top performer, with Longhorn, Portworx, and OpenEBS following in that order.
As a leading enterprise Kubernetes-native distributed storage product, IOMesh helps customers build elastic, reliable, and highly performant storage resource pools for stateful applications, in a Kubernetes-native way. By reducing the cost and complexity of adopting persistent storage, IOMesh assists enterprises in accelerating cloud-native transformation.
