One New Zealand’s Strategic Shift to Red Hat OpenShift Virtualization

Why It Matters

By consolidating VMs and containers on OpenShift, One NZ reduces operational complexity and accelerates digital initiatives, setting a benchmark for telecoms seeking cloud‑agnostic, vendor‑neutral architectures.

Key Takeaways

• One NZ migrated <5% of apps classified as hard workloads.
• Red Hat Virtual Migration Factory automated VM-to-OpenShift migrations.
• Unified ops now apply same automation to VMs and containers.
• Upgrade cycles cut from months to weeks or days.
• Teams upskilled via Red Hat learning squads, avoiding new hires.

Pulse Analysis

Telecommunications operators have long wrestled with a two‑stack dilemma: legacy virtual machines coexist with newer containerized services, inflating management overhead and stalling innovation. One New Zealand’s strategic decision to adopt Red Hat OpenShift Virtualization marks a deliberate pivot toward a single, cloud‑agnostic platform. By aligning its C1 core‑modernization program with a mature Kubernetes ecosystem, the carrier sidesteps vendor lock‑in and creates a horizontal cloud foundation that can scale across its entire service portfolio.

The migration was orchestrated through Red Hat’s Virtual Migration Factory, a repeatable framework that blends automated tooling with Ansible‑driven workflows. Workloads were triaged by complexity, revealing that under 5% required intensive effort, allowing the internal team to execute bulk migrations with minimal external dependence. This systematic approach not only accelerated the transition but also preserved continuity for critical services, demonstrating how telcos can modernize without disruptive overhauls.

Operationally, the convergence of VMs and containers under a unified OpenShift layer has yielded tangible benefits: automation, observability and policy enforcement now span all workloads, reducing mean‑time‑to‑upgrade from months to weeks or days. Consolidated hardware footprints improve power efficiency and increase node utilization, while targeted learning squads equipped engineers with the skills to manage both legacy and cloud‑native environments. For the broader industry, One NZ’s experience illustrates that virtualization need not be a legacy anchor; instead, it can serve as a bridge to a fully containerized future, delivering speed, flexibility and cost savings.
