| Spec score · Virtualization Management Software | 9.0 (#1) | 8.1 (#8) |
| API | CloudStack exposes a documented, extensible REST-like API and supports Amazon EC2 and S3-compatible APIs. | ZSvirt 1.0.0 documents a RESTful API with definitions for all APIs and more than 2,000 REST/OpenAPI endpoints claimed on the product site. |
| CLI | CloudMonkey is the project’s command-line and shell environment for interacting with CloudStack clouds. | Environments can be operated through a command-line interface in addition to the web UI and API. |
| Documentation depth | Official documentation covers concepts, topology, quick installation, full installation, administration and complex configurations. | Documentation includes quick start, installation and upgrade tutorials, user guides, Terraform material, API reference, SDK specifications and FAQs. |
| Extensibility | A pluggable adapter framework supports custom hypervisor, storage, network and authentication integrations. | The architecture supports plugin-based extension of resource types, business capabilities and integrations. |
| High availability | Management servers can run in a load-balanced multi-node installation and MySQL can use replication for failover. | VM HA can automatically reboot virtual machines after host failure, with configurable global and cross-cluster policies. |
| Integrations | The integrations page lists Terraform, Ansible, Kubernetes, Prometheus, VMware NSX, Ceph, MinIO, and billing portal integrations. | The site lists SDKs for Go, Python, and Java, native Terraform providers, GitOps, and 2,000+ REST/OpenAPI endpoints. |
| License | The project website states that Apache CloudStack is licensed under the Apache License, Version 2.0. | The core project is released under the GNU GPL version 3.0. |
| Networking | Networking features include VLANs, virtual routers, firewalls, load balancers, VPN, IPv6, static routing, BGP and VNF support. | Networking includes virtual networks, distributed switches, distributed port groups, security groups, VLAN/VXLAN/flat topologies and SR-IOV. |
| Rating on Capterra | 5.0 out of 5 from 1 review | 0.0 out of 5 from 0 reviews |
| Scale | The documentation says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. | The maker claims one control plane can manage more than 10,000 hosts and virtual machines with up to 768 vCPUs. |
| Security reporting | Vulnerabilities in released versions are reported to the Apache security team at [email protected]. | The project asks researchers to report vulnerabilities privately to [email protected] or [email protected] rather than public GitHub issues. |
| Storage | Storage capabilities include iSCSI, NFS, Ceph RBD with KVM, block volumes, encryption, snapshots, templates and ISO management. | Storage capabilities include primary and backup storage, volumes, snapshots, image storage, local storage, NFS, SAN and distributed storage. |
| Support | Users can seek community help through the project mailing list, and the project says some companies offer commercial support. | The open-source release has community support; Enterprise adds LTS releases, SLAs, and vendor-backed production support. |
| What it does | Apache CloudStack deploys and manages large virtual-machine networks as a highly available, scalable IaaS platform. | ZSvirt is an open-source virtualization platform for managing virtual machines, clusters, hosts, storage and networks from a centralized control plane. |

In their own words
Apache CloudStack
Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.
ZSvirt
ZSvirt is an open-source, self-hosted virtualization platform based on ZStack’s ZSphere virtualization engine. It uses KVM and the site says one control plane can manage 10,000+ hosts, with VMs of up to 768 vCPUs. The ZSvirt Open Source plan has no license fee and no VM limit; it is offered with community support. Live migration, high availability, disaster recovery and API access are listed capabilities.
For VMware migration, ZMigrate supports agentless full-disk replication, incremental sync and cutover in as little as five minutes. Listed security features include VM SecureBoot, vTPM 2.0, encryption, security groups, MFA/2FA and immutable audit logs. Integration options include Go, Python and Java SDKs, native Terraform providers, GitOps and 2,000+ REST/OpenAPI endpoints. Storage and compatibility options include distributed storage integrations, SAN support, the KVM ecosystem, VMDK, and mainstream hardware and guest operating systems. Downloads include x86_64 ISO, OVA and QCOW2 images, plus the ZMigrate package. Enterprise adds advanced multi-cluster and compliance capabilities, LTS releases, SLAs and vendor-backed production support.
