Architectural Evolution and Best Practices. By restricting communication between specific applications, microsegmentation limits the attack surface and contains breaches even if an adversary gains access to the internal fabric.
Why East West Traffic Dominates Modern Networks and What It Means for Your Infrastructure
Unlike north south traffic, which is easily monitored at the edge, internal communication can be opaque without the right tools. Consequently, infrastructure teams must prioritize non-blocking fabrics and high-speed links, such as 25G or 100E interconnects, to ensure that the internal conversation does not become the weakest link in the chain.
Traditionally, network design prioritized north south traffic, which moves in and out of the data center to and from external users on the internet. Understanding this shift is essential for optimizing infrastructure, as the two traffic types demand different approaches to bandwidth, latency, and security.
The Rise of East West Traffic in Modern Network Architectures
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. However, the dramatic rise of virtualization, containerization, and microservices has shifted the center of gravity, making east west traffic—the communication between servers and applications inside the data center—dominant.
