The Evolution of Network Configuration Management#

Tim Raphael

• Why: Config management is where the PM's declarative/intent-driven world (Kubernetes-style APIs) meets traditional networking — a well-structured survey of the evolution from hand-crafted configs to intent-driven operations is useful context for anyone building network tooling.
• What: A journey through the evolution of configuration technologies and lessons learned: scripting, imperative operations, workflows, playbooks, APIs, RPCs, declarative models, and intent-driven operations — and how networks should be configured going forward (from abstract only).
• How: Conceptual/survey talk tracing the maturity curve rather than a single tool or case study.
• Where applicable: Broadly applicable; most valuable as a shared-vocabulary framing for where an organisation sits on the imperative-to-declarative spectrum.
