For many years, city planners built elevated highways. It was their way of bypassing congested surface arteries without digging up neighborhoods. But over time, the planners found that elevated highways didn’t improve conditions — they instead made them worse.
Virtual networks (VLANs) and outdated micro-segmentation strategies are like elevated highways, as they’ve created more problems for network engineers. Complicated overlays make networks difficult to manage and lack the fabric-wide security that’s needed to protect critical data.
