ZStack

ZStack provides self-hosted cloud infrastructure software for organizations managing compute, networking, storage and related services in data centers. Its product scope includes private cloud, virtualization, AI infrastructure, hyperconverged infrastructure, storage, networking, container cloud and multi-cloud management. ZCF combines compute, storage, networking, containers and security in a software-defined private-cloud platform with a unified portal, operations and identity management. It manages hosts, disks, images and snapshots, with scheduling and elastic scaling.

ZStack supports KVM virtualization, elastic bare metal and management of heterogeneous virtualization platforms. ZStone provides block, file and object storage, while Zaku supports Kubernetes cluster creation and container management alongside virtual machines. ZStack Cloud Enterprise integrates with Alibaba Cloud, offers a RESTful API and supports local, cross-region and hybrid-cloud backup and recovery. The product range also includes high-availability policies and a UI migration service for cloud hosts running mainstream Windows and Linux systems. Listed free plans offer full features for three months for ZStack ZSphere or one year for ZStack Cloud. ZLR enterprise disaster recovery is marked as coming soon.

ZStack spans private cloud, virtualization, storage and container infrastructure, with deployment and plan details varying by product. Check regional availability and the stated ZLR status when assessing a particular need.

ZStack suits enterprises managing infrastructure in their own data centers, including organizations with security, compliance, stability or performance requirements. Its offerings cover industries such as education, manufacturing, finance, healthcare and government.

ZStack is a self-hosted infrastructure platform for enterprises running private-cloud environments. It is best suited to infrastructure teams that need to manage compute, virtualization, storage and containers together. Its free deployment options lower the entry cost, but the one-server cap on ZStack Cloud and the regional limits on Standard matter.

Overview

ZStack covers private cloud, virtualization, AI and hyperconverged infrastructure, storage, networking, container cloud and multi-cloud management. ZStack Cloud provides IaaS management for data-center compute, network and storage; ZCF combines those resources with containers and security in a software-defined private cloud with unified portal, operations and identity management. That breadth is useful for organizations consolidating infrastructure operations, but it is a more substantial choice than a standalone virtual-machine manager.

The company, Shanghai Yunzhou Technology Co., Ltd., is headquartered in Shanghai and was founded in 2015. ZStack describes its products as enterprise infrastructure for organizations including education, energy, manufacturing, finance, telecommunications, healthcare and government.

Key features

ZCF manages cloud hosts, disks, images and snapshots, and supports scheduling, elastic scaling and scheduled tasks. Its KVM virtualization, elastic bare metal and management of heterogeneous virtualization platforms can suit teams operating mixed environments; supported hypervisors include KVM, XDragon and VMware vSphere. Live migration and high availability are supported, valuable for maintaining service continuity as infrastructure changes.

ZStone supplies block, file and object storage, with optional replication or erasure coding and support for existing SAN, NAS and shared block storage. This flexibility can help organizations incorporate existing storage investments, though the stated capabilities do not establish which configuration a particular deployment will require.

Zaku supports one-click Kubernetes cluster creation and management, orchestration, Helm and image repositories, and management of containers alongside virtual machines. ZCF can also manage public-cloud resources and integrates with Alibaba Cloud; its network virtualization is based on OVN/OVS. The native RESTful API and API Explorer support development with HTTP-enabled languages, while installation files, SDKs and a high-availability suite are available for deployment planning.

Security capabilities include vTPM 2.0, Secure Boot, KMS key management, role-based access controls, audit logs and national-cryptography encryption. ZStack says its ZCF-based compliance capabilities support classified cybersecurity protection and cryptographic assessment construction. These are relevant to compliance-focused organizations, but the platform's enterprise orientation means teams should evaluate their own requirements and configuration.

ZStack Cloud Enterprise supports local, cross-region and hybrid-cloud backup and recovery. A UI-based migration service can move cloud hosts running mainstream Windows and Linux systems to ZStack Cloud. ZLR enterprise disaster recovery is marked as coming soon, with capabilities and metrics subject to the released version, so it should not be treated as a current production option.

Pricing

The pricing model is freemium, with a free plan and a 365-day trial. ZStack ZSphere costs nothing and includes full features and unlimited server deployment for three months. It suits teams that want to explore a multi-server deployment without a subscription charge, but the free period is limited to three months.

ZStack Cloud costs nothing and includes full features for one year, but is limited to single-server deployment. That is a practical starting point for evaluation or a small deployment, not a substitute for multi-server capacity. ZStack Cloud Standard is available only in selected regions. No paid-plan price is given, so larger or ongoing deployments should be assessed on custom pricing.

Platforms

ZStack is self-hosted and supports Linux, web and API access. Its deployment files, historical versions, images and SDKs give infrastructure teams material for installation and development, while documentation, training videos, certification training, a community and knowledge base provide support resources. Separate sales and after-sales phone options are also available.

Who it's for

ZStack is a strong fit for enterprises building private clouds in their own data centers, especially those with high security, compliance, stability or performance requirements. Teams seeking a shared management environment for virtual machines, storage and Kubernetes may benefit from its scope. It is a weaker fit for users seeking a small desktop virtualization tool or for organizations that require a mature ZLR disaster-recovery service now.

Pros and cons

• Pros: Broad private-cloud, storage, virtualization and container management can bring core infrastructure operations under one platform.
• Pros: Free plans offer full features, including unlimited server deployment in ZSphere for three months, making initial evaluation accessible.
• Pros: Security controls, hybrid-cloud integration and backup options address enterprise operating needs.
• Cons: The ZStack Cloud free plan is capped at one server, limiting its usefulness for multi-server production environments.
• Cons: Standard is region-restricted, and ZLR's enterprise disaster-recovery capabilities are not yet released.

Alternatives

For a broader shortlist, see Virtualization Management Software. Choose Proxmox VE when a freemium virtualization option with Linux, Windows, web and Android platforms better matches your environment. Citrix Secure Private Access is a paid option for readers focused on secure access to web and SaaS applications rather than full private-cloud infrastructure.

VMware Workstation Pro is a free option for Windows or Linux hosts when the need is desktop-hosted virtualization. Choose Apache CloudStack for free, open-source IaaS without commercial plan pricing. LXD offers free, self-hosted KVM-based virtual machines and system containers; oVirt is a free open-source virtualization solution; and virt-manager is a free Linux self-hosted option.

Virtuozzo Infrastructure is another freemium choice, with a self-install plan capped at 96 physical cores and 1TB of storage.

Verdict

Choose ZStack if your organization needs a self-hosted enterprise platform that brings private cloud, virtualization, storage and containers into one operating environment, with meaningful security and hybrid-cloud capabilities. Look elsewhere if you need a multi-server free ZStack Cloud deployment, broad regional access to Standard or released enterprise disaster recovery through ZLR.
