Storage Implications of a Modern IT Architecture

Why It Matters

Persistent storage is the linchpin that enables containers to support mission‑critical, stateful workloads, directly influencing enterprise agility, AI readiness, and compliance with data‑sovereignty mandates.

Key Takeaways

• 71% plan to migrate VMs to Kubernetes, per Portworx report
• 58% intend to run stateful databases on Kubernetes
• Longhorn V2 delivers up to four‑fold write performance boost
• Edge and satellite workloads demand resilient persistent storage solutions
• SAP targets 120 PB European sovereign storage with Ceph and Rook

Pulse Analysis

Containerisation has outgrown its original stateless niche, becoming the backbone for both cloud‑native microservices and legacy enterprise apps. Recent surveys reveal that a majority of large enterprises are moving workloads to Kubernetes, driven by the need for faster provisioning and the flexibility to run AI and analytics at scale. However, the shift introduces a storage dilemma: containers are inherently ephemeral, yet modern workloads demand data that persists beyond a pod’s lifecycle. This tension is amplified by edge and satellite deployments, where intermittent connectivity and harsh environments make resilient, low‑latency storage a non‑negotiable requirement.

Enter the new generation of cloud‑native storage solutions. SuSE’s Longhorn V2 bypasses the traditional Linux kernel stack, allocating dedicated CPU cores to achieve up to four times faster writes and dramatically lower latency for random reads. Portworx, now part of Everpure, adds enterprise‑grade features that span hybrid, on‑premise, and public‑cloud environments, simplifying automation and VM‑container coexistence. Open‑source projects such as Ceph and its Kubernetes orchestrator Rook are also gaining traction, especially for data‑sovereignty initiatives. SAP’s 120 PB European storage fabric exemplifies how organizations are leveraging these technologies to retain control over data location while supporting petabyte‑scale workloads.

For CIOs and infrastructure leaders, the implications are clear: storage strategy can no longer be an afterthought in a container‑first roadmap. The performance gains from solutions like Longhorn V2 can offset the cost of over‑provisioned high‑speed disks, while the flexibility of Portworx and Ceph/Rook enables seamless migration from legacy VMware estates. Moreover, as AI models grow and edge devices proliferate, the ability to guarantee data persistence across distributed nodes becomes a competitive differentiator. Enterprises that align their storage architecture with these emerging capabilities will unlock faster time‑to‑market for innovative services and maintain compliance with increasingly stringent data‑residency regulations.
