Platform engineering before it had a name: Automating test environments at scale

Marc Hornbeek discusses a real-world platform engineering success story from a global network systems manufacturer, long before the term “platform engineering” existed. Faced with severe release delays caused by manual, error-prone test environment setup, his team designed and operated a self-service internal platform that automated the provisioning, reservation, monitoring, and release of complex test environments.

By embedding environment intent directly into test cases and abstracting infrastructure complexity behind a simple notation, the platform transformed developer workflows, increased test infrastructure utilization, and became the enterprise standard for testing at scale. The talk highlights timeless platform engineering principles that remain directly applicable to modern internal developer platforms.
