ZStack Cloud v5.4.0 LTS Preview: Ushering in a New Era of Intelligent Cloud

Recently, ZStack Cloud released the brand-new 5.4.0 (LTS), a major leap forward following the 4.8.0 LTS version launched in 2024. This release delivers comprehensive enhancements across core cloud capabilities, platform openness, O&M experience, security compliance, and ecosystem integration—aimed at providing a stronger, smarter cloud foundation for enterprise digital transformation.

Since the release of 4.8.0 LTS, ZStack Cloud has continued to evolve through rigorous validation in thousands of customers’ production environments. ZStack Cloud v5.4.0 LTS is not a mere accumulation of features; it is a system-level reconstruction and innovation driven by deep insight into customers’ future needs. The core value of this upgrade lies in:

A new paradigm for global O&M governance: a unified perspective for complex environments

To address common complex private cloud deployment scenarios such as dual-active across two sites and multi-availability-zone architectures, ZStack Cloud v5.4.0 LTS introduces a multi-availability-zone management solution. Users can manage resource pools from different availability zones within the same UI—for example, managing both 4.8.x and 5.4.0 clusters simultaneously—achieving a unified login portal, unified user authentication, and unified authorization management.

This solution ensures continuous stability for production workloads while providing a safely isolated environment for technology evolution and validation. Enterprises can fully explore advanced capabilities in the new version without impacting the smooth operation of core business, striking the optimal balance between “stability” and “innovation.”

Platform-level breakthroughs: from a “feature cloud” to an “ecosystem cloud”

Pluggable framework for flexible integration: ZStack Cloud v5.4.0 LTS introduces a brand-new pluggable management framework. By standardizing and modularizing the integration interfaces for various resources (such as cryptographic devices and authentication services), users can integrate third-party services as easily as installing mobile apps, dramatically reducing the cost and timeline of customization.

Broad compatibility to embrace a diverse technology ecosystem: The platform has pursued deep integration with mainstream technology components across networking, compute, security, and identity management. For example, it supports unified monitoring and O&M for mainstream GPU devices; enables automatic configuration delivery to mainstream SDN controllers with tenant-level resource isolation; and integrates with multiple cryptographic devices to support commercial cryptography transformation needs—ensuring a stable, efficient cloud experience across diverse technology choices.

Application marketplace to extend cloud value: A feature-rich marketplace offers curated apps such as Zaku container management, the ZStack AI model platform, and ZStack CMP multi-cloud management. With one-click deployment, the platform extends capabilities from IaaS up to PaaS and SaaS, building a truly “application-centric ecosystem platform.”

Together, these capabilities mark ZStack Cloud’s evolution from a fixed-function cloud into a highly open platform.

Comprehensive enhancements to cloud infrastructure: more efficient, more reliable, higher performance

Across compute, networking, storage, and O&M, ZStack Cloud v5.4.0 LTS consolidates the best from numerous rolling releases since 4.8.0:

Compute: Smarter HA mechanisms prevent accidental manual-triggered failovers; SR-IOV NIC VMs now support seamless live migration with an experience on par with vNIC.

Networking: Support for PVLAN delivers fine-grained isolation; shared bandwidth reduces public network costs; OVS-DPDK provides a high-performance data plane; deep integration with mainstream SDN controllers.

Storage: New primary storage options such as Vhost and CBD support high-performance distributed storage integration, and introduce CDP with second-level recovery, providing solid assurance for business continuity.

Operations & Maintenance: End-to-end O&M support spans monitoring and alerting, automated script execution, and unified GPU device management. Multi-channel real-time alert push is supported, and a script library plus file upload improves day-to-day O&M efficiency.

The release of ZStack Cloud v5.4.0 LTS embodies our commitment to productization and our response to enterprise demands for a cloud platform that is stable, agile, intelligent, and secure. It is more than a technical upgrade—it redefines the role of the cloud platform: evolving from a resource pooling tool into a digital foundation that supports enterprise business innovation and intelligent operations. We believe ZStack Cloud v5.4.0 LTS will help customers face the future with greater confidence.
