Cozystack vs ... — head-to-head comparisons

Cozystack against the platforms it replaces, head-to-head

Direct, side-by-side comparisons of Cozystack against the platforms it commonly replaces. Each comparison goes through compute, storage, networking, multi-tenancy, observability, backup/DR, GPU, sovereignty posture, operational footprint, license, and migration pattern — at the level of detail a platform engineer needs to make an architecture call.

Cost comparisons with sourced prices

The four write-ups above are architectural. For the money, the TCO calculator compares five-year cost against thirteen platforms, with each price carrying a source, a date and a source-nature label, and each page stating the case where the other platform wins:

Nutanix · VMware · OpenShift · Proxmox VE · OpenStack · CloudStack · OpenNebula · Harvester · Rancher · Virtuozzo
