VMware Replacement Best Practice at Dayou Futures

Abstract: As VMware subscription costs keep climbing, even regulated financial firms are moving to open alternatives. As one of China’s well-known futures brokerage firms, Dayou Futures had long run its core trading and settlement systems on VMware, and with subscription costs rising it replaced the platform with ZStack ZSphere, the enterprise edition of ZSvirt. The solution keeps an operation experience close to the original platform while ensuring the high availability and real-time performance of trading and settlement workloads, eliminating vendor lock-in and significantly reducing IT budget.

About ZSvirt

This case study was implemented with ZStack ZSphere, the enterprise edition of ZSvirt. ZSvirt is the open-source version of ZSphere, sharing the same enterprise-grade virtualization core and providing the same capabilities in smooth migration, high-performance virtualization, broad hardware compatibility, and heterogeneous chip support. The business scenarios, solutions, and best practices shown in this case can be fully reproduced with ZSvirt — the free, GPL-3.0 open-source edition. Open-source users can obtain the stability and reliability of enterprise-grade virtualization and complete a VMware replacement at zero license cost, with no vendor lock-in.

1. Customer Background

Dayou Futures Co., Ltd. is one of China’s well-known futures brokerage firms. It had long used VMware as its core virtualization platform, carrying key business systems such as trading and settlement. Trading workloads place extremely high demands on availability, real-time performance, and stability — any interruption can have a business impact.

The company required a virtualization platform that was independent of any single vendor and free of licensing lock-in. At the same time, VMware’s shift to a subscription model kept pushing costs up, adding year-over-year IT budget pressure.

2. Business Challenges

  • Rising subscription costs: VMware’s subscription pricing kept climbing and became a major source of long-term IT cost pressure.
  • No vendor lock-in: Core trading and settlement systems needed to run on a platform independent of any proprietary vendor and its licensing terms.
  • High load, real-time demands: Trading and settlement workloads are heavy and require high performance, high availability, and real-time assurance from the platform.
  • Familiar operating habits: The team had used VMware for years, so the replacement platform needed to minimize learning and adaptation cost.

3. Solution

Dayou Futures adopted ZStack ZSphere, the enterprise edition of ZSvirt, to fully replace VMware and build a high-performance virtualization platform free of vendor lock-in:

  • Full VMware replacement: Supports mainstream hardware and operating systems, with no dependence on proprietary vendors.
  • High-performance architecture: Delivers high-performance virtualization to keep trading and settlement systems stable under high load.
  • Smooth migration with familiar experience: The interface and operating logic are close to VMware, greatly reducing adaptation cost during migration.
  • Heterogeneous chip support: Supports heterogeneous architectures such as x86 and ARM, providing flexibility for future expansion and selection.

4. Solution Highlights

  1. No vendor lock-in: Full support for mainstream hardware and operating systems, reducing dependence on proprietary vendors.
  2. High performance and availability: Provides stable, real-time, highly available virtualization for high-load trading environments.
  3. Zero-learning-cost migration: Operating logic is highly consistent with VMware, so teams can get started seamlessly.
  4. Heterogeneous architecture flexibility: x86+ARM heterogeneous chip support, built for future expansion.

5. Business Benefits

  • Significantly lower cost: After replacing VMware, IT budget spending decreased notably.
  • Stable business operations: Trading and settlement systems run stably, ensuring high availability and real-time performance.
  • Technology independence: Core workloads run on an open platform the team fully controls, with no vendor lock-in.
  • Preserved O&M expertise: A VMware-like operating experience means the O&M team does not need to rebuild skills.

6. Best Practice Summary

Core financial trading systems demand extremely high stability, performance, and compliance from the virtualization platform. The key practices in this case are:

  • Select for independence: Treat freedom from vendor lock-in as a primary criterion in platform selection;
  • Reduce risk with familiar experience: Choose a solution whose operating logic is close to the original platform to lower migration adaptation cost;
  • Prioritize performance for business: Carry core trading and settlement workloads on a high-performance, high-availability architecture;
  • Advance smoothly and gradually: Migrate in phases with smooth transition to maximize business continuity.
