Infrastructure Comparisons¶
Neutral, side-by-side comparisons of the infrastructure platforms and clouds covered in this knowledge base. Each comparison links back to the topic pages it draws on and includes a "which one should I pick?" decision flowchart. Facts were aligned with the topic pages on 2026-09-25.
Comparison Notes¶
| Comparison | Scope |
|---|---|
| Infrastructure Platforms Comparison | Docker 29.8 vs Kubernetes 1.37 vs OpenStack 2026.1 vs OpenNebula 7.4 across stack layers: architecture, scalability, operations, security, cost, lock-in and use-case fit |
| Proxmox VE vs OpenNebula vs OpenStack | The three private-infrastructure platforms on an ambition axis: architecture, operations, tenancy, backup, cost, and weighted decision matrices for VMware replacement and multi-tenant cloud |
| Public Cloud Landing Zones | AWS vs Google Cloud vs Alibaba Cloud vs Tencent Cloud: account hierarchy, guardrail semantics, landing-zone services and blueprints, identity, transit networking, audit, IaC and a service mapping |
