This course provides a clear and practical understanding of how modern data centres are designed to support scale, resilience, and cloud-native workloads. Participants explore the shift from traditional three-tier networks to leaf-spine architectures, software-defined networking concepts, and the separation of control and data planes. The course explains how automation, overlays, and policy-driven design enable faster deployment, multi-tenancy, and predictable performance. Emphasis is placed on understanding failure domains, east-west traffic patterns, and the operational realities of running high-availability data centre networks. By the end of the course, delegates will be able to interpret modern data centre designs, engage effectively with vendors and architects, and make informed decisions about capacity, resilience, and scalability.
Pre-requisites: Basic IP networking concepts; familiarity with Ethernet and routing fundamentals.
