Why a Maturity Model#

Platform engineering investments fail when organizations skip levels. A team that cannot maintain shared Terraform modules reliably has no business building a self-service portal. The maturity model provides an honest assessment of where you are and what must be true before advancing.

This is not a five-year roadmap. Some organizations reach Level 2 and stay there — it serves their needs. The model helps you identify what level you need, what level you are at, and what is blocking progress.

Two Approaches to the Same Problem#

Both Port and Backstage solve the same core problem: giving developers a single interface to discover services, provision infrastructure, and understand the operational state of their systems. They take fundamentally different approaches to getting there.

Backstage is an open-source framework (CNCF Incubating) originally built by Spotify. You deploy and operate it yourself. It provides a plugin architecture and core primitives — you build the portal your organization needs by assembling and configuring plugins.

What an Internal Developer Platform Actually Is#

An Internal Developer Platform (IDP) is the set of tools, workflows, and self-service capabilities that a platform team builds and maintains so application developers can ship code without filing tickets or waiting on other teams. It is not a single product. It is a curated layer on top of your existing infrastructure that abstracts complexity while preserving the ability to go deeper when needed.
