Okestro said on the 16th that as VMware win-back cases surged throughout 2025, win-back revenue for its server virtualization solution CONTRABASS topped 10 billion won.
Since Broadcom's acquisition of VMware, changes in licensing policies and price hikes centered on foreign-made virtualization solutions have continued, expanding transition demand premised on so-called "de-VMware" among public institutions and corporations. As a result, reviews and adoption of server virtualization solutions that can replace existing VMware environments are gaining momentum.
Amid these shifts, Okestro has rapidly increased VMware win-back cases centered on its server virtualization solution CONTRABASS. According to the company, as of 2025, VMware win-back cases rose about sevenfold from the previous year, while over the two years since 2023, win-back references expanded about twentyfold and order value about twenty-fourfold.
These results are also reflected in CONTRABASS revenue metrics. In 2025, win-back revenue within CONTRABASS sales topped 10 billion won for the first time. The company said the figure shows that replacement transitions in the domestic server virtualization market, which had been centered on VMware, are moving into the actual adoption phase.
Kim Beom-jae, CEO of Okestro, said, "Transitioning from a VMware environment is not a simple system swap but a task that simultaneously demands service continuity and stability," and added, "We will respond to VMware transition demand based on the win-back experience we have accumulated."
