Thai Home Improvement Retailer

A leading home improvement and building materials retailer in Thailand, facing challenges such as high VMware subscription costs and the difficulty of managing multiple distributed branches, has successfully adopted the ZStack Cloud platform to achieve a seamless VMware Alternative. The solution supports the reuse of existing servers and iSCSI/FC SAN storage, combined with flexible licensing models, to significantly reduce TCO. With its high availability, scalability, unified operations, and seamless migration capabilities, the solution was first successfully deployed in the Nakhon Sawan and Phuket branches. The company now plans to roll out this migration across all 47 branches nationwide, establishing a replicable path for retail chains to achieve a VMware Alternative and cloud-native transformation.

The retailer operates across six major regions in Thailand, managing 47 branches that provide a full range of products for professional engineering and DIY projects. Its decentralized operational model demands high stability, scalability, and cost-control for IT infrastructure. Previously, all branches relied on VMware virtualization. As the business expanded, the high costs of VMware’s subscription model, hardware lock-in, and the complexity of managing multiple stores became significant pain points. The enterprise urgently needed an enterprise-grade cloud platform capable of 100% core scenario replacement, protecting existing investments, and supporting long-term expansion.

ZStack stood out after months of rigorous market selection, functional testing, and comprehensive evaluation, thanks to its full coverage of VMware core features, hardware compatibility, and high-availability architecture. By choosing ZStack Cloud as the core IT architecture for its new Nakhon Sawan branch, the client leveraged ZStack’s hardware-reuse capabilities. The platform seamlessly integrated existing servers and iSCSI/FC SAN storage, eliminating the need to replace legacy equipment or purchase additional hardware. A single-node deployment was completed in under 30 minutes, enabling rapid IT system rollout for the new branch while maximizing the protection of existing IT assets.

Furthermore, ZStack Cloud offers flexible licensing models—including CPU core-based, physical server-based, or subscription-based options. This on-demand, cost-controllable approach perfectly aligns with the budget characteristics of retail chains with distributed branches and phased investment cycles, effectively breaking free from the continuous cost pressure of VMware’s subscription-only model.

ZStack Cloud’s full-stack high availability has become a cornerstone of this partnership. The platform eliminates single points of failure through multi-management node HA, ensures automatic business recovery via VM HA, and provides multi-path storage redundancy. This creates comprehensive protection from the infrastructure layer to the business layer, delivering 99.99% SLA and meeting the 7×24 continuous operation requirements of retail businesses. During the six months of stable operation at the Nakhon Sawan branch, the platform experienced zero downtime, earning the deep trust of the enterprise IT team. Based on this success, the client again chose ZStack Cloud for its new branch in Phuket, utilizing the unified management interface to rapidly replicate the proven solution.

For the nationwide upgrade plan covering 47 branches, ZStack Cloud’s high-elasticity deployment provides a perfect fit. A single cluster supports smooth expansion from 1 to 1,000 servers, allowing for a phased, full-domain migration as the business grows without the need for architectural re-engineering. During the transition, the platform supports unified management of multi-version VMware environments, significantly reducing cross-platform management complexity. The migration process utilizes ZStack’s agentless ZMigrate technology, following a “Five-Step Migration Method” (Preliminary Research – Business Assessment – Solution Planning – Implementation – Post-Management), ensuring a smooth transition without business interruption, with full control over data integrity and consistency.

This partnership delivers multiple core values to the Thai retail giant:

• Significant Cost Optimization: By reusing existing servers and SAN storage, combined with flexible licensing and resource reuse, the TCO is reduced by over 50% compared to VMware subscriptions, effectively alleviating budget pressure.
• Reliable Stability: The full-stack high-availability architecture and 99.99% SLA guarantee support the continuous operation of core business systems across all branches, eliminating the risk of business interruption due to hardware failure.
• Operational Efficiency: The unified graphical management platform integrates intelligent monitoring, alerting, and batch operations, significantly improving O&M efficiency and reducing the need for cross-system switching and manual intervention.
• Clear Expansion Path: A progressive upgrade path—from single-branch pilot to nationwide migration—combined with high-elasticity scaling, perfectly aligns with the enterprise’s long-term expansion strategy.
