In contrast, east west traffic never leaves the internal fabric; it moves horizontally between virtual machines, bare metal servers, storage arrays, and other services. Attackers who breach the perimeter can move laterally across the internal network with relative ease, targeting vulnerable services that communicate freely.
Business Processes Traffic Impact in East West vs North South Network Architectures
This requirement has driven the adoption of leaf spine architectures, which replace traditional three-tier models to provide predictable, non-blocking connectivity. Database replication, distributed caching, and service-to-service API calls all rely on the underlying network’s ability to handle microbursts and maintain low round-trip times.
Traditionally, network design prioritized north south traffic, which moves in and out of the data center to and from external users on the internet. North south traffic enters the data center through an edge, traverses core and distribution layers, and reaches a final server before exiting back to the user or another external service.
How Business Processes Traffic Impact East West Versus North South Flows
In a leaf spine layout, every leaf switch connects to every spine switch, creating multiple equal-cost paths that prevent bottlenecks. The result is a fabric capable of supporting massive server-to-server communication without sacrificing speed, a critical requirement for modern distributed applications.
