Globalization 2.0 | South Pacific Telecom Operator Adopts ZStack Cloud to Carry Core Business Workloads

A telecommunications operator in the South Pacific has built a next-generation cloud infrastructure to carry its core business workloads on the ZStack Cloud platform. By leveraging ZStack Cloud’s multi-storage integration capabilities and highly reliable architecture, the operator has significantly improved resource utilization and business continuity, providing a solid foundation for regional communication services and digital transformation.  

As a key force in theregion’s digital infrastructure, this leading local telecom operator has been deeply involved in the communications industry for nearly three decades. Its business covers 172 islands nationwide, offering broadband access, mobile communications, and enterprise/government IT services. The company is not only a crucial driver of local digital transformation but also an important pillar in safeguarding public communication needs.  

In recent years, with broadband users growing at an annual rate of 18% and private cloud demand from enterprise/government clients rising by 25% annually—particularly for high I/O and highly reliable storage—the operator’s traditional architecture of “physical servers + scattered storage” has encountered significant bottlenecks. Three core pain points emerged:  
1. Low Resource Utilization

Existing SAN storage utilization was below 30%, and NFS storage suffered from mounting difficulties, leading to substantial resource idling and waste.  
2. Poor Business Experience & Agility

During peak periods, service stuttering rate reached as high as 8%. New business deployment cycles took up to 15 days, dragging customer satisfaction down to 75%.  
3. System Reliability Challenges

Annual business downtime exceeded 12 hours, severely impacting service reputation and brand image.  

To address the storage and architecture challenges brought about by rapid business growth, the customer conducted a comprehensive evaluation and ultimately chose the ZStack Cloud platform, mainly for the following key advantages:  
Multi-Storage Seamless Integration  
1、Supports mainstream SAN storage systems such as HPE and IBM, compatible with FC/iSCSI/NVMe protocols, without additional adaptation, enabling quick integration with existing storage resources.

2、Supports NFS and local storage, enabling “Local + SAN + NFS” hybrid deployment to flexibly meet different business scenario requirements.

High Availability and Stability  
1、Telecom-grade high-availability architecture shortens automatic failover time to the minute level, ensuring business continuity.

2、Multi-path redundancy allows for link failover in seconds, preventing business interruptions.Improved Operational Efficiency  
1、Unified monitoring and alerting with Teams notification support, reducing operational complexity.

2、Fully UI-based SAN storage integration shortens deployment time from 3 days to just 4 hours.

With ZStack Cloud’s computing and storage capabilities, the customer built an integrated “compute-storage-network” cloud platform to carry its core external services.  
Solution Details:  
Computing Resource Pool: Integration of 10 HPE physical servers into a high-availability computing cluster to support critical workloads.

Storage Resource Pool: Integration with HPE SAN storage, using thin provisioning to optimize utilization and allowing direct LUN device mounting to cloud hosts.

Integrated NFS storage to meet file sharing and backup needs.

Storage utilization improved from 30% to 85%, activating idle resources.

Network & High Availability Architecture:  
Multi-path redundancy to avoid single points of failure.

Automatic failover reduced to minutes; annual downtime dropped from 12 hours to 0.5 hours.

Thanks to ZStack Cloud’s multi-storage integration and highly available architecture, the operator has successfully built a stable and efficient cloud platform, laying a solid foundation for future business expansion. Storage utilization has improved significantly, saving USD $150,000 annually in procurement costs. Business deployment cycles have been reduced from 15 days to 2 days, operational efficiency has greatly increased, and system stability has improved along with the overall user experience.
