Storage vendors realize they must provide storage for containerized applications, and are moving to do that through internal development, extending their traditional products or by acquiring new technology.
According to Evaluator Group’s Spring 2021 Hybrid Cloud Study, 84% of enterprises have already adopted or are planning to adopt containers. One-third will keep a mix of traditional and container-based workloads, 29% said it is a goal to move most or all workloads to containers, and 18% have already done so. 
With the rise in the use of containers for production applications, these apps need persistent storage. Developers are taking responsibility for storage and data services when building applications. Kubernetes allows them to automate the process of allocating storage along with compute and network for containerized apps.
That has led to the emergence of container-native storage (CNS), also known as cloud-native storage, designed for DevOps’ storage and data services requirements. Besides allowing developers to deploy storage in Kubernetes, CNS must also provide enterprise services that IT ops require. Vendors are taking several approaches to providing storage for containers, either through CNS or container storage interface (CSI) drivers that expose capacity to Kubernetes
Startups have emerged specifically with CNS designed for the DevOps community. These include Diamanti, Ionir, Ondat, Portworx (now part of Pure Storage) and Robin.io. Established storage vendors have extended capabilities around their CSI drivers to bring data services to containerized applications. These include Dell EMC Container Storage Modules (CSM) and NetApp Trident and Astra. Some have adapted traditional storage products to run natively in containers, such as IBM Spectrum Fusion and Veritas InfoScale. And others have developed CNS as part of their container management platforms, such as Red Hat OpenShift Data Foundation and SUSE Rancher Longhorn.
These products enable provisioning persistent volumes through Kubernetes, but are in various stages of maturity and enterprise-readiness. The goal is to provide tools that gives developers self-service when deploying storage while also enabling IT Ops to maintain control over enterprise data.
