An in-depth comparison to help you choose the right cloud infrastructure solution for your business.
Overview
Apache CloudStack
Apache CloudStack is an open-source IaaS platform that manages compute, networking, and storage to build public or private clouds. It supports KVM, VMware, and XenServer hypervisors.
VMware vSphere/vCloud
VMware vSphere is the industry-leading virtualisation platform, providing enterprise-grade hypervisor (ESXi), management (vCenter), and a comprehensive cloud infrastructure stack.

Pros & Cons
Apache CloudStack
Advantages
- Completely free and open-source (Apache 2.0)
- No per-CPU or per-VM licensing
- Multi-hypervisor support (KVM, VMware, Xen)
- AWS-compatible API
- Simple single-server to multi-zone scaling
- Active community and commercial support options
Considerations
- Smaller ecosystem than VMware
- Fewer enterprise GUI management tools
- Requires Linux admin expertise
- Less polished UI compared to vSphere
VMware vSphere/vCloud
Advantages
- Industry gold standard for virtualisation
- Mature, polished vSphere client UI
- vMotion, DRS, HA — enterprise features
- Massive ecosystem and partner network
- NSX for software-defined networking
- Extensive training and certification paths
Considerations
- Very expensive per-CPU licensing (Broadcom era)
- Broadcom acquisition creating uncertainty
- License changes forcing subscription model
- Vendor lock-in concerns
Our Recommendation
With VMware licensing costs skyrocketing under Broadcom, Apache CloudStack offers a compelling zero-license-cost alternative that many service providers and enterprises are adopting. For organisations already invested in VMware and dependent on features like vSAN and NSX, a phased migration approach makes sense. Xcobean operates its own CloudStack-powered infrastructure and can help you plan and execute a migration.
