Abstract
Modern data centres constitute the physical substrate of modern information systems (IS), yet their operational management often relies on fragile, manual workflows. This poster presents a hybrid NetDevOps automation framework designed to resolve the structural vulnerabilities of purely stateless Infrastructure as Code (IaC) pipelines. The architecture introduces a model-driven mathematical schema that deterministically derives expansive routing identifiers (e.g., 4-byte ASN, loopbacks, and 24-bit VNIs) directly from topological semantics. Simultaneously, it integrates NetBox as a stateful Single Source of Truth (SSoT) exclusively for constrained resources (e.g., VLANs), effectively preventing index-shift anomalies. The orchestration layer combines Ansible playbooks, Jinja2 templates, and the NETCONF protocol to enable transactional, idempotent provisioning of Juniper network devices. Validated in a dual-site EVPN-VXLAN emulation environment, the framework acts as a strict procedural enforcer, eliminating configuration drift and elevating network management into a reproducible, declarative, and auditable engineering discipline.

Infrastructure as Code in Distributed Data Centre Information Systems: An Automation Framework Based on Ansible, NETCONF, and Model-Driven Configuration
Modern data centres constitute the physical substrate of modern information systems (IS), yet their operational management often relies on fragile, manual workflows. This poster presents a hybrid NetDevOps automation framework designed to resolve the structural vulnerabilities of purely stateless Infrastructure as Code (IaC) pipelines.
