T-Mobile Pulls Tens of Thousands of VMs Off VMware

T-Mobile is migrating tens of thousands of virtual machines off VMware while suing Broadcom over the licensing terms behind the platform, per Ars Technica.

The move counts as one of the largest publicly confirmed examples of enterprise flight from VMware since Broadcom overhauled its licensing after buying the company. A carrier running infrastructure at T-Mobile's scale doesn't pull tens of thousands of VMs on a whim. That's the point for anyone still running production workloads on VMware under Broadcom's new terms.

The lawsuit and the migration are happening at the same time, which tells you T-Mobile isn't waiting on a courtroom outcome to protect itself. It's hedging with its infrastructure while it fights the licensing dispute directly.

Perpetual licenses aren't perpetual when someone new owns the terms. That's the lesson here. It applies past VMware: any vendor relationship built on licensing terms set before an acquisition is worth checking against whoever holds the contract now. Watch whether other large VMware customers file similar suits or quietly start their own migrations. If T-Mobile's exit is a leading indicator rather than an outlier, expect more within the year.

Ars Technica's report landed on July 2, as Broadcom's VMware licensing overhaul keeps pushing large customers toward the exits.
