Capability matrix
What you get, by substrate — without the brochure fog.
Funded competitors bury you in checklists. This is the product surface that matters for multi-cluster production, scored for the three substrates Zeus runs as first-class.
| Capability | EKS | GKE | Proxmox/k3s | Notes |
|---|---|---|---|---|
| Cluster provision & lifecycle | Full | Full | Full | Same workflow; cloud plumbing differs at the seam |
| Import existing clusters | Yes | Yes | Yes | Manage alongside Zeus-created clusters |
| Global fabric (encrypted overlay) | Yes | Yes | Yes | Non-colliding IPAM, default-deny grants, probes |
| Cross-cluster service discovery | Yes | Yes | Yes | By name, real IPs, mesh CA in pods |
| Multi-region databases | Yes | Yes | Yes | MySQL, PG, ClickHouse, Yugabyte — shared ops board |
| Engine-honest failover controls | Yes | Yes | Yes | MySQL multi-cluster auto-arbiter when eligible |
| Mesh DNS (internal) | Yes | Yes | Yes | Health-aware names inside the fabric |
| Public multi-region DNS | Yes | Yes | Yes | Route53 / Cloud DNS + external probers |
| No-kubectl service deploys | Yes | Yes | Yes | One definition; Advanced shows real manifests |
| Environments & layered config | Yes | Yes | Yes | Defaults → env → cluster |
| Cloud IAM (IRSA / Workload Identity) | IRSA | WI | N/A* | Per-service identities where the cloud supports it |
| Builds & multi-arch images | Yes | Yes | Yes | Dedicated builders; Harbor scanning |
| Live observability | Yes | Yes | Yes | Pods, logs, metrics across the fleet |
| Workload rightsizing | Yes | Yes | Yes | CPU/memory/throttling findings + suggested limits from live metrics |
| Day-two upgrades & teardown | Yes | Yes | Yes | Guided flows; clean destroy checklists |
| Edge / secure zones | — | — | Yes | Default-deny zones on your hardware |
* On-prem identities use cluster RBAC and Connections — not AWS/GCP workload identity. Cloud IAM applies when the workload runs on EKS or GKE.
How to read this
Full / Yes
Shipped product surface you can demo and run in production.
Seam differences
UX is the same; provider plumbing (IAM flavor, node naming, registry) is resolved at deploy time.
Not listed
Single-cloud managed DB products, proprietary runtimes, or CNI monocultures — by design.
