Platform Engineering at Scale

Challenge

A major European broadcasting organization faced a central challenge: infrastructure that had grown over many years needed to be modernized while at the same time laying the foundation for a future-proof cloud-native platform.

The focus was on building an Internal Developer Platform (IDP) that enables development teams to provision infrastructure resources in a standardized, self-service manner via Kubernetes APIs. The goal was to bring more speed and autonomy to development without giving up the necessary control and stability.

In a broadcasting environment like this, that is critical: systems must operate reliably at all times, whether new features are being built in the background, deployments are running, or data is being processed. Failures or inconsistencies here have an immediate impact on operations, content, and reach.

An additional challenge was designing stable platform APIs with a clearly defined lifecycle. They were to follow Kubernetes conventions, with Alpha, Beta, and GA versions as well as transparent support periods, so that changes could be planned and risks in day-to-day operations minimized.

Solution

To deliver this, a central API layer was built that acts as a single interface between development teams and infrastructure.

Using Crossplane and Helm Charts, AWS resources such as databases, OpenSearch, networks, or monitoring stacks can be provisioned declaratively and via self-service. Infrastructure becomes a standardized, repeatable part of the platform instead of a manual, error-prone process.

Provisioning follows the GitOps model with ArgoCD. Changes are rolled out in a structured, traceable way across Development, Staging, and Production environments, ensuring consistent and controlled operations.

The platform is complemented by policy enforcement via Kyverno, centralized authentication through Entra ID (SSO), and end-to-end observability with Prometheus, Grafana, and OpenTelemetry.

A key part of the solution is automated release management: Release Please and Renovate prepare version updates automatically and roll them out in a controlled way via Pull Requests. Semantic Versioning and Conventional Commits provide clear structure, while automatically generated changelogs offer full transparency into what changed.

The platform APIs follow the same principles: they are clearly versioned, include defined deprecation periods, and make breaking changes visible and plannable early on.

Impact

The new platform provides a stable, scalable foundation that sustainably simplifies operations while significantly accelerating development workflows.

New platform versions can be rolled out automatically and reliably without disrupting live operations. Development teams gain clear guidance from structured API versioning and can plan and implement changes more safely.

In practice, that means less coordination overhead, fewer manual steps, and a much lower error rate, with higher velocity when delivering new requirements.

At the same time, centralized control over the platform is retained. Standards, security, and governance are upheld consistently while teams can work flexibly and autonomously.

This creates a technical foundation that not only runs stably but also grows with future needs—reliable, traceable, and ready for the next stage of development.
