Western Union is moving its massive server infrastructure away from VMware in a high-stakes migration to Nutanix, marking a significant shift in the company’s approach to its virtualized environment. The move comes as the 175-year-ancient financial services giant seeks to distance itself from Broadcom, the company that acquired VMware and subsequently overhauled its licensing models.
The transition is already well underway. Brandon Shaw, Western Union’s vice president and head of technology services, revealed that the company is six months into a migration involving between 900 and 1,200 applications. These workloads are distributed across a server fleet totaling 3,900 cores, representing a substantial portion of the company’s digital backbone.
This decision to migrate to Nutanix is not merely a technical swap but part of a broader corporate “re-invention.” Shaw noted that Western Union is working to turn into more customer-focused, a goal that has made the organization more open to exploring latest suppliers who can better align with its operational needs and long-term strategy.
The Friction with Broadcom’s Licensing
The catalyst for the departure appears to be a combination of partnership friction and the cost of new licensing structures. While Shaw acknowledged that Western Union maintained “decent lines of communication” with Broadcom and continued to use some of its non-VMware software, he admitted the company faced “challenges partnering with them.”
A primary point of contention is Broadcom’s shift toward a bundled licensing strategy. Under the new regime, customers are largely pushed toward the Cloud Foundation private cloud suite. While the suite is technically powerful, it often carries a price tag considerably higher than the legacy licensing agreements users had previously held for VMware products.
For a global entity like Western Union, these costs are compounded by the demand for extreme flexibility. The company operates in over 200 countries, many of which have strict data sovereignty laws requiring certain workloads to remain in-country. Shaw indicated that Nutanix provides superior flexibility for workload placement, ensuring that applications can be deployed to the specific infrastructure required by local regulations regardless of the region.
Managing the Migration Risks
Moving thousands of cores and over a thousand applications is rarely seamless. Shaw described the current stage of the migration as an exercise in problem-solving, particularly when dealing with legacy software. He noted that the process often requires refactoring old code or, in some cases, determining that certain software is no longer necessary and can be decommissioned entirely.
Beyond the technical hurdles, Western Union had to weigh the business risk of switching to another vendor. The possibility of Nutanix itself being acquired was a concern during the evaluation process. To mitigate this, Nutanix’s legal team included continuity assurances in the sales negotiations. According to Shaw, these guarantees “made us perceive comfortable with the longevity of the deal.”
Shaw characterized the resulting partnership between Western Union and Nutanix as “symbiotic,” suggesting a closer alignment of goals than the previous relationship with Broadcom.
A Growing Trend of VMware Departures
Western Union is not alone in its exodus. At the .NEXT conference, Nutanix highlighted other organizations making the switch, including Everland, South Korea’s largest theme park. Jinyoung Woo, an IT infrastructure engineer at Everland, explained that the park previously relied on VMware Cloud on AWS but struggled with product quality and the prohibitive cost of Broadcom’s revised licenses.
Everland’s transition was particularly urgent, with a narrow three-month window to migrate. The organization considered moving to native cloud virtual machines (VMs) but ultimately chose Nutanix to minimize disruption. The move was completed within the deadline with no reported impact on customer experience.
| Driver | Western Union | Everland |
|---|---|---|
| Primary Catalyst | Licensing costs & partnership friction | Licensing costs & product quality |
| Technical Need | Global workload flexibility (200+ countries) | Rapid migration (3-month window) |
| Scale | 3,900 cores / 900-1,200 apps | Theme park operations |
The Broader Market Impact
The ripple effect of Broadcom’s acquisition of VMware is creating a significant opportunity for competitors. Nutanix CEO Rajiv Ramaswami believes the company is a viable alternative for approximately 165,000 of VMware’s existing customers. He expects these migrations to occur in “waves,” triggered by the end-of-life status of specific VMware products or the arrival of license renewal deadlines.
Ramaswami noted that Nutanix is currently winning between 500 and 1,000 new customers every quarter, many of whom are former VMware users seeking a more collaborative supplier relationship. Some of these migrations are massive in scale, with reports of entities moving over 100,000 cores to the Nutanix platform.
Despite these losses, Broadcom remains optimistic. The company has predicted nine percent growth in its software business and is promoting its memory tiering technology as a solution to high memory prices, suggesting that the value of the Cloud Foundation suite will eventually outweigh the initial sticker shock for many enterprises.
As Western Union continues its migration, the industry will be watching to see if other legacy enterprises follow suit, potentially accelerating the shift toward hyperconverged infrastructure (HCI) as a primary alternative to traditional virtualization.
The next major indicator of this trend will be the upcoming quarterly earnings reports from both Nutanix and Broadcom, which will reveal whether the volume of “competitive wins” is enough to offset Broadcom’s aggressive growth targets.
