ZStack

ZStack is a self-hosted infrastructure platform for organizations operating private clouds and data centers. It is best suited to enterprise infrastructure teams that want to manage compute, storage, networking and containers together. Its breadth is compelling, but the free deployments have different scope limits and ZStack Cloud Standard is restricted to selected regions.

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 a shared portal, operations and identity management.

This breadth can suit teams that want virtual machines, containers and storage under one infrastructure environment. It is aimed at operators building and managing enterprise infrastructure, not people seeking a general desktop virtualization tool. Shanghai Yunzhou Technology Co., Ltd. is headquartered in Shanghai and was founded in 2015.

Key features

ZCF manages hosts, disks, images and snapshots, with scheduling, elastic scaling and scheduled tasks. It supports KVM virtualization, elastic bare metal and heterogeneous virtualization management; listed hypervisors include KVM, XDragon and VMware vSphere. Live migration and high availability are supported, useful for teams consolidating virtualization operations and continuity policies in one platform.

ZStone offers block, file and object storage, with optional replication or erasure coding and compatibility with existing SAN, NAS and shared block storage. That range can help organizations integrate different storage needs without limiting the platform to a single storage type. Zaku creates and manages Kubernetes clusters, supports orchestration plus Helm and image repositories, and can manage containers alongside virtual machines.

ZCF can manage public-cloud resources, including Alibaba Cloud, and uses OVN/OVS for network virtualization. ZStack Cloud Enterprise integrates with Alibaba Cloud across control and data planes. Enterprise backup supports local, cross-region and hybrid-cloud backup and recovery, while migration tools move cloud hosts running mainstream Windows and Linux systems through a UI.

Security capabilities include vTPM 2.0, Secure Boot, KMS key management, role-based access controls, audit logs and national-cryptography encryption. The company says ZCF-based compliance supports classified cybersecurity protection and cryptographic assessment construction. ZLR enterprise disaster recovery is marked as coming soon, with capabilities and metrics subject to its released version; organizations choosing it for that specific need should account for that gap.

A native RESTful API, API Explorer, installation files, high-availability suite, historical versions, images and SDKs support deployment and development. Documentation, training videos, certification training, a community and knowledge base provide operational resources, alongside separate sales and after-sales phone options.

Pricing

ZStack uses a freemium model with a free plan and a 365-day trial. ZStack ZSphere costs nothing and provides unlimited server deployment with full features for three months. Its server allowance makes it the more suitable option for evaluating multi-server deployment, but the free period is shorter.

ZStack Cloud costs nothing and provides single-server deployment with full features for one year. That longer period suits a single-server evaluation or deployment, but the one-server cap makes it a weaker fit for teams assessing a broader cloud footprint. ZStack Cloud Standard is available only in selected regions, so regional eligibility matters before selecting a plan.

Platforms

ZStack is self-hosted and supports Linux, web and API access. Its installation files and SDKs support deployment and development, while its native RESTful API works with HTTP-supported languages. The self-hosted model suits organizations running infrastructure in their own data centers, but places deployment and operation within that environment.

Who it's for

ZStack is strongest for enterprise infrastructure teams building private clouds where security, compliance, stability or performance are priorities. Its industry solutions include education, energy, manufacturing, finance, telecom, healthcare and government. Teams that need to manage compute, storage, networks, virtual machines and Kubernetes together have a clear reason to consider it; those needing ZLR enterprise disaster recovery now should look elsewhere until that product is released.

Pros and cons

• Broad infrastructure coverage: ZCF, ZStone and Zaku span private cloud, multiple storage types and Kubernetes alongside virtual machines.
• Enterprise security and continuity features: Access controls, audit logs, encryption, live migration and high availability address common infrastructure requirements.
• Free options have useful but distinct scopes: ZSphere permits unlimited server deployment for three months, while ZStack Cloud permits one server for a year.
• Regional restriction: ZStack Cloud Standard is available only in selected regions, which can rule it out for some deployments.
• Disaster recovery gap: ZLR is still marked as coming soon, so it is not a dependable choice for teams requiring that enterprise offering immediately.

Alternatives

For a broader comparison, see Virtualization Management Software. Choose Proxmox VE instead if its free plan and platform range better fit your virtualization needs; its Premium plan is priced per occupied physical CPU socket. Virtuozzo Infrastructure is another freemium option, with a self-install plan capped at 96 physical cores and 1TB of storage.

Apache CloudStack is a free IaaS alternative. Consider LXD for a free, self-hosted option covering KVM-based virtual machines and system containers, or oVirt for its free community virtualization edition. VMware Workstation Pro, virt-manager and Xen Project Hypervisor are also alternatives.

Verdict

Choose ZStack if your enterprise team wants a self-hosted control plane that brings private-cloud compute, storage, networking, virtualization and containers together, with security and hybrid-cloud capabilities. Its two free deployment options provide meaningful ways to evaluate or run the platform, but their server limits differ, regional availability can constrain ZStack Cloud Standard, and ZLR is not yet ready. Look elsewhere if those limits conflict with your deployment or disaster-recovery requirements.
