White Paper: What Is Platform Engineering?
Platform Engineering, Thursday, July 2nd, 2026
Platform engineering is the evolving discipline of building the shared layer between developers and infrastructure complexity.
This white paper by Alan Shimel defines platform engineering as the discipline of building the shared layer between developers and underlying infrastructure complexity, distinct from a rebrand of DevOps.
It traces the discipline's evolution across eras from server management to Kubernetes, internal developer platforms, observability, and now AI and agentic systems.
While technologies shift from servers to containers to GPUs, the core responsibility of standing between developers and raw complexity remains constant.
Modern platform teams now manage GPU capacity, model serving, vector stores, AI gateways, and agent identity.
The central thesis is that platform engineering is a dynamic discipline that follows the application rather than freezing around any single tool or era.
