Platform Engineering Knowledge Base

Build and Operate an Internal Developer Portal with Confidence

A practitioner-focused resource for tech leads, platform engineers, internal dev tool builders, and engineering managers. Every guide is organized around the real work sequence — architecture, security governance, plugin extensibility, and developer experience — with concrete configuration, validation, and maintenance playbooks.

Jump straight into implementation guides with runnable YAML/JSON/TypeScript examples, health checks, and the failure modes you will actually hit in production.

How the portal fits together

Internal developer portal reference architecture Source systems feed an ingestion layer that normalizes entities into a catalog, which is served through an access-controlled portal to engineers. Source systems Git & CI/CD Kubernetes Cloud APIs Ingestion & normalization Service catalog + TechDocs Portal OIDC / RBAC Plugins Self-service Engineers discover, document, and ship services through one governed control plane.
A developer portal acts as one governed control plane over your existing source systems.

Main sections

Architecture & Frameworks

Choose, structure, and scale the portal platform — Backstage, Docusaurus, or MkDocs.

Authentication, RBAC & Security

SSO, least-privilege access, audit trails, and governance for internal tooling.

Plugin Ecosystem & Extensions

Build, test, and publish custom plugins, catalog integrations, and UI components.

Developer Experience & Self-Service

Golden paths, onboarding automation, DevEx metrics, and internal API discovery.

Quick access guides

Choosing the Right Framework

Compare platform options and trade-offs for your organization.

Backstage Architecture Deep Dive

Plan service boundaries, plugins, and operational architecture.

OIDC & SSO Configuration

Set up secure SSO integration patterns for internal portals.

RBAC Setup

Define and enforce least-privilege access across portal workflows.

Building Custom Backstage Plugins

Create plugin capabilities aligned with your internal platform model.

Golden Paths & Paved Roads

Standardize the fastest safe route from idea to running service.

How to use this portal

Start with your goal: pick the section that matches your immediate need — architecture decisions, identity and RBAC controls, plugin implementation, or developer experience.

Follow an implementation flow: most guides are structured for execution — prerequisites, configuration, validation, maintenance, pitfalls, and FAQ.

Ship with confidence: use the included YAML/JSON/TypeScript/bash examples and checklists to move from proof-of-concept to production-ready platform operations.
