Enterprise platform engineering — internal platforms for organizations at scale

Open-source Cozystack (a CNCF project we create and maintain) Ænix Platform, the supported commercial distribution Aenix builds, operates and migrates it.

Enterprise platform engineering is the discipline of building and operating internal platforms for large organizations that run many product teams across multiple business units, regions, and jurisdictions. At this scope, multi-tenancy, governance, audit-readiness, and ops-at-scale are mandatory rather than optional. It targets engineering organizations of roughly 500+ people with 5+ teams sharing one platform and multi-cluster, multi-region operations. Aenix delivers this on Cozystack, an Apache 2.0 CNCF Sandbox project that runs VMs and containers on one Kubernetes API via KubeVirt, with Cilium (eBPF) networking, LINSTOR/DRBD storage, and structural Tenant-CRD multi-tenancy. Aenix combines a Platform Readiness Assessment, the productized Ænix Platform, and hands-on engineering to build a platform-as-a-product with fleet management and identity-integrated RBAC.

Quick facts

  • What it is The discipline of building and operating internal developer platforms for large, multi-team, multi-business-unit organizations at sustained scale.
  • Who it's for Engineering organizations of ~500+ people with 5+ product teams sharing a platform, cross-BU isolation, and multi-cluster / multi-region operations.
  • How Aenix delivers Platform Readiness Assessment, then a 6-18 month Phase 2 implementation on Cozystack with the productized Ænix Platform.
  • Multi-tenancy Structural via the Cozystack Tenant CRD; equivalent abstractions where other stacks (e.g. OpenShift Project CRD) apply.
  • License Apache 2.0 (no per-CPU / per-core licensing)
  • Status Cozystack is a CNCF project (Sandbox since 2025-02-28; Incubating expected late summer 2026)

Enterprise platform engineering is the discipline of building and operating internal platforms for organizations with multiple product teams, cross-BU isolation, and sustained scale. It’s a different scope from “platform engineering for a single team” — multi-tenancy, governance, and ops-at-scale are non-negotiable.

Pairs with: Ænix Private Cloud Platform — regulated multi-DC operation plus the developer self-service layer that an enterprise IDP needs.


When enterprise scope matters

  • 5+ product teams sharing platform
  • Multi-BU separation required
  • Cross-jurisdictional sovereignty constraints
  • 500+ engineering organization
  • Multi-cluster / multi-region operations

For smaller scope (single-team or 1-3 teams), see platform engineering services with default scope.


What’s different at enterprise scale

  • Multi-tenancy structural — Tenant CRD on Cozystack; OpenShift Project CRD; equivalent abstractions.
  • Governance integration — RBAC integrates with workforce identity; audit-readiness for compliance.
  • Multi-cluster operation — fleet management, federation, regional consistency.
  • Platform-as-a-product — internal product management discipline.
  • Capacity planning — quarterly review at organizational level.

Frequently asked questions

How is enterprise platform engineering different from platform engineering for a single team?

Scope. Single-team platform engineering optimizes for one or a few teams. Enterprise scope adds non-negotiable multi-tenancy, cross-business-unit isolation, governance, audit-readiness, and multi-cluster operations across regions and jurisdictions. For 1-3 teams, Aenix offers its standard platform engineering services instead.

When does an organization actually need the enterprise scope?

Typically when 5+ product teams share a platform, multiple business units must be separated, cross-jurisdictional sovereignty constraints apply, the engineering organization is 500+ people, or operations span multiple clusters and regions. Below that, the default-scope platform engineering engagement is a better fit.

What technology does Aenix use to build enterprise platforms?

Cozystack, an Apache 2.0 CNCF Sandbox project. It runs VMs and containers on one Kubernetes API through KubeVirt, uses Cilium (eBPF) for networking, LINSTOR/DRBD for storage, and the Tenant CRD for structural multi-tenancy. Aenix layers the productized Ænix Platform and engineering services on top.

How long does an enterprise platform engagement take?

It begins with a Platform Readiness Assessment to scope the work. Phase 2 implementation for an enterprise platform typically runs 6-18 months, reflecting the added complexity of multi-tenancy, fleet management, governance, and multi-region consistency.

How does governance and identity work at enterprise scale?

RBAC integrates with workforce identity, and the platform is built for audit-readiness to support compliance requirements. Multi-tenancy is structural rather than convention-based, so business units and teams are isolated at the platform layer instead of relying on manual process.

Is there per-core or per-CPU licensing?

No. Cozystack is Apache 2.0 with no per-CPU or per-core licensing. Aenix monetizes the productized Ænix Platform and services on top, with subscription tiers rather than core-based license fees.
