In this video, I break down the five core layers of a Platform Engineering reference architecture and explain how they come together to form an Internal Developer Platform (IDP). This video builds on the first episode in the series and shifts the conversation from what Platform Engineering is to how to think about designing and standardizing your own platform. I walk through the reference architecture, the role each layer plays, and some of the tooling and design decisions I’m using as I build out the Virtual Elephant IDP. We’ll cover why the observability plane and security plane are foundational, how the integration and delivery plane supports automation and GitOps workflows, what belongs in the resource plane, and how the developer control plane ultimately shapes the user experience for your engineers and developers. I also highlight why a CMDB / single source of truth is so important for long-term platform success, and preview how this series will move into more tactical implementation topics like NetBox, GitOps, and developer portals. If you’re building an IDP, evaluating Platform Engineering, or trying to standardize the ecosystem around Kubernetes, GitOps, observability, and developer self-service, this video will give you a strong conceptual foundation. 📺 Watch the full series playlist: 💡 Don’t forget to: ✅ Like this video if you find it helpful. ✅ Subscribe to the channel for more home lab, cloud-native tutorials and project showcases. ✅ Drop a comment with your thoughts or questions about the project.
