The company’s Virtuozzo Storage for Kubernetes provides persistent storage for cloud native environments and applications running on the container orchestration platform. It runs on commodity hardware and is built on Virtuozzo’s SDS solution.
Specific aspects of the SDS product include dynamic volume provisioning based on preconfigured storage classes for a particular container volume; support for the Kubernetes 1.7 aggregation application programming interface (API) to provide functionality “snapshots” for Kubernetes volumes; and its FlexVolume Driver to provide mount volumes on Kubernetes nodes.
A Kubernetes volume is a directory that can include some data from within the container, and it is accessible to the containers in a pod. A volume can have a longer lifecycle than its host container, up to the lifecycle of the pod, which itself houses multiple containers.
The Virtuozzo Kubernetes product allows for the management of storage clusters and other storage services – including object storage. This runs alongside control over Kubernetes native storage-related objects, defining storage classes and automatically snapshotting policies.
Object storage manages data as objects, as opposed to files or blocks, and is typically used in the cloud.
Virtuozzo’s Kubernetes product joins its existing support for Docker containers. As part of a software stack update earlier this year, the company added the ability for users to deploy and manage containers, virtual machines (VMs), and storage from a single platform.
In updating its own SDS container storage platform earlier this month, Irshad Raihan, senior manager of product marketing at Red Hat’s storage team, explained “persistent volumes allow developers to be closer to their goal of storage being as-a-service, highly elastic, and not holding them back.”
Raihan said the container storage market was still evolving, with many organizations just now realizing the diverse needs required by their deeper push into cloud platforms.
“Eighteen months ago, storage was not a pain point for the earliest of adopters,” Raihan said. “They had not gotten to that point yet. Once they got to the point where they needed persistent storage, they finally realized the need.”
As for the SDS market, Raihan noted it was still not to the level of mainstream adoption, but “it’s getting to be an easier conversation to have.”
In a study published earlier this month, IDC forecasts worldwide SDS revenues will reach nearly $16.2 billion by 2021, experiencing a compound annual growth rate of 13.5 percent between 2017 and 2021.
