Data Center Network Transformation Sign 2: Core & Pod Design

The 2nd concrete sign of DC network transformation is deployment topology that leverages core & pod design principles. A pod is a self-contained unit of compute, network and storage; in our context, a “pod” is used interchangeably with a “pod network.” Most traditional network designs have been based on a 20-year architectural premise, based on a N-tier hierarchical topology. As data center traffic shifted to east-west, the N-tier architecture led to a highly oversubscribed network that impacted application performance, created resiliency nightmares and resulted in long and complex troubleshooting workflows. Cloud Giants figured out that a different model was needed.
