A global technology company specializing in network performance and lifecycle automation for communication service providers (CSPs) wanted to modernize its legacy visualization environment. With its existing VMware-based infrastructure becoming increasingly expensive and difficult to manage, the client faced challenges around scalability, upgrade cycles and disaster recovery (DR). What should have been a routine infrastructure operation was turning into a time-consuming, high-risk activity that diverted IT bandwidth away from innovation and business enablement.
The client partnered with Persistent to lead this transformation, leveraging deep virtualization expertise and proven modernization frameworks to help the client build a cost-predictable, resilient and future-ready infrastructure platform.
Gaps in Existing Virtualization Environment
The client’s existing VMware based, three‑ tier infrastructure‑ was unable to support the client’s growing business needs, which demanded greater scalability, faster releases and predictable operations.
- Escalating licensing costs: Virtualization licensing costs were driving a projected 30–45% increase in total cost of ownership (TCO).
- Operational complexity: Lengthy and disruptive upgrade cycles increased risk and downtime.
- Limited scalability: Capacity constraints reduced agility and hindered growth
- Inefficient DR: Complex processes made resilience harder to achieve.
- High operational overhead: Significant manual effort impacted IT productivity and slowed innovation.
The client needed a cost-predictable, highly available‑ and automated alternative to support both current operations and long-term‑ modernization goals.
From Legacy Virtualization to Modern Infrastructure
Persistent partnered closely with Nutanix, a leader in hybrid multi-cloud computing, to deliver a structured transition from VMware to a hyperconverged infrastructure (HCI) platform.
By combining Nutanix’s integrated, enterprise-ready HCI platform with Persistent’s deep virtualization and migration expertise, the joint solution enabled a smooth, low-risk modernization journey while maintaining business continuity.
The engagement focused on:
- Unified HCI platform: Migrated from VMware to Nutanix AHV to consolidate infrastructure into a single HCI stack.
- Simplified operations: Centralized lifecycle and virtualization management using Nutanix Prism, reducing upgrade complexity and eliminating multi‑tool dependency.
- Licensing simplification: Eliminated VMware hypervisor licensing by adopting Nutanix’s integrated subscription‑based HCI model.
- Built‑in resiliency and visibility: Enabled native high availability, DR and platform‑level observability through Nutanix.
Persistent delivered end-to-end services, including architecture design aligned to Nutanix best practices, a scalable migration factory model, automated assessment and validation, integrated disaster recovery, and GenAI-assisted pre-and-post-migration validation.
Redefining Infrastructure Efficiency
By modernizing its virtualization environment, the client significantly reduced operational burden while improving performance and reliability. The impact included:
- 38% reduction in TCO
- $1.2M projected savings over three years
- 99.99% platform uptime post-‑modernization
- 24%–32% performance improvement across core workloads
- 40% reduction in daily operational effort
- 500 virtual machines migrated with zero major incidents
- Upgrade cycles reduced from hours to minutes
- SLA compliance improved from 95% to 99.7%
- Product release timelines accelerated by three months
With a modern, resilient and cost-effective virtualization platform, the client is positioned to scale with predictable operations and long-term value.
As enterprises reassess their virtualization strategies amid rising licensing costs and increasing operational complexity, Persistent, in partnership with Nutanix, is helping them confidently move away from legacy virtualization models and adopt a resilient foundation built for scale.
