The Architecture Nebula: Enterprise Platform Architecture for VMs, Kubernetes, Data, and AI

This article introduces the 'architecture nebula' as a mental model for enterprise platform architecture, emphasizing a governed operating model rather than a collection of infrastructure products. It describes a stable platform core that provides contracts, policy, lifecycle, and operational gravity, with orbiting capabilities such as compute, storage, networking, identity, security, Kubernetes, data services, automation, observability, and AI. Using examples like VMware Cloud Foundation, Azure, AWS, Terraform, and Kafka, the article argues for a vendor-neutral approach where heterogeneous environments behave as one governed platform. It explains the metaphor as a dependency map, highlighting relationships like gravity (dependency), shields (security), telescopes (observability), and comets (automation). The content is technical and relevant to IT professionals, architects, and platform engineers.
