Globalization 2.0 | Cambodia DPDC × ZStack Helps Enterprises Achieve VMware-to-ZStack

Cambodia’s digital wave is advancing from “connectivity” to “intelligence.” ZStack, in collaboration with Cambodia’s Daun Penh Data Center (DPDC), has implemented a four-step approach—”legacy-first, architecture upgrade, multi-tenant governance, and 24/7 dedicated service”—to achieve VMware-to-ZStack transformation. This case study highlights 100% reuse of old servers, a 60% reduction in licensing costs, and a reduction in resource delivery time from three days to half a day. The ZStack team provides 24/7 real-time support, ensuring 99.99% high availability. The hybrid cloud-ready foundation co-created by both parties is becoming a core engine for digital transformation among Cambodian enterprises.

Daun Penh Data Center, based in Phnom Penh, Cambodia, is a local company specializing in data center services. It is a ZStack customer in Cambodia and a key partner. DPDC offers colocation, dedicated servers, virtual private servers (VPS), cloud servers, and network hosting services, with a total capacity of over 750 servers, featuring redundant power and cooling systems to ensure 99.99% high availability. Its services cover local data exchange in Cambodia and IP Transit lines to Hong Kong, Singapore, and Thailand.

ZStack’s Smooth Four-Step Construction

Legacy-First Seamless Migration
Compatibility Assurance: ZStack supports seamless integration of existing VMware environment servers and storage devices (FC SAN/iSCSI/NFS) without hardware replacement.
Data Migration: Using the Zmigrate agentless migration tool, VMware virtual machines are hot-migrated online to the ZStack platform with zero business interruption.

Architecture Upgrade Hybrid Cloud Ready
Hybrid Cloud Ready: A private cloud foundation is built on the ZStack Cloud platform, with reserved interfaces for Alibaba Cloud public cloud integration, supporting hybrid cloud expansion.
Flexible Storage Configuration: Simultaneous access to FC SAN high-performance storage and local disks (LocalStorage) allows for tiered deployment of critical business and test environments.

Multi-Tenant Governance Precise Billing
Resource Isolation: Independent VPC networks and computing resources are divided by department/project, ensuring data isolation between tenants (e.g., finance systems and R&D environments).
Automated Operations: Users apply for resources through self-service tickets, and the platform automatically generates billing reports based on CPU/memory/storage usage, enabling precise cost tracing.

Service Assurance 24/7 Response
24/7 Dedicated Support: The ZStack technical team establishes a VIP group for real-time response to DPDC, providing support and fault handling.

Transformation from Cost Center to Efficiency Engine
Economic Improvement
Zero Licensing Costs: The perpetual licensing model saves over one million yuan annually in VMware subscription fees.
Resource Utilization Boost: Virtualization cluster CPU utilization increased from 15% to 45%, with idle servers being restarted and utilized.
Operational Quality Change
Minute-Level Fault Response: The ZStack support team is available 24/7, improving major incident handling efficiency by 90%.
Automated Operations: Billing reports are automatically generated, reducing IT manpower investment by 50%.
Business Agility
Accelerated Resource Delivery: New project resource delivery and deployment time reduced from three days to half a day.
