: Building security into the initial architecture—using Zero Trust Access and micro-segmentation—rather than adding it as a secondary layer.
: All IT resources (servers, storage, clients) are interconnected across a converged foundation.
: Breaking the network into smaller, functional modules (e.g., Campus, Data Center, WAN) to limit failure domains and simplify upgrades. Designing for Cisco Network Service Architectur...

Cisco utilizes two primary frameworks to guide network design: the traditional hierarchical model for physical structure and the for service integration.
