Data center migrations quickly get complicated. Large-scale migrations often result in a tangle of conditional DNS forwarding rules which require constant management and upkeep. Avoiding service disruptions in this constantly changing environment requires a great deal of effort. With BlueCat’s Intelligent DNS, you can protect against downtime by controlling the DNS resolution path. If a query returns a ‘not-found’ (NXDOMAIN) result, Intelligent DNS will re-route the query according to a pre-defined logic, ensuring services are always reachable by users.
