Cloud-Native Container Storage Versus CSI Plug-Ins

By: Lucas Mearian, Ashish NadkarniGroup Vice President, Infrastructure Systems, Platforms and Technologies Group

Abstract

This IDC Perspective presents an overview of persistent storage for containerized environments through use of the container storage interface (CSI). The difference between CSI-attached storage and a container-native storage application is nuanced; the CSI interface is used to attach storage volumes to containerized applications, but container-native storage software fills the role of SDS, enabling data generated by containerized workloads to be replicated, migrated, and protected. The main difference is container-native apps package data services that can run in the same cluster as the apps they support.

"As container adoption grows, being able to support modern applications with persistent storage and data services, including backup, migration, and security, will be a key differentiator among technology providers," said Lucas Mearian, research manager, Infrastructure Systems, Platforms and Technologies Group at IDC. "How those services are delivered will also be important as organizations are seeking the most efficient and user-friendly methods in an IT generalist, DevOps environment."
