Key Takeaways
  • Data center migrations often introduce complex, hard-to-maintain webs of conditional DNS forwarding rules.
  • Frequent DNS rule changes during large-scale migrations increase the risk of service disruption and operational overhead.
  • Controlling the DNS resolution path is critical to maintaining service availability in dynamic, multi-environment networks.
  • BlueCat Intelligent DNS can automatically re-route queries that return NXDOMAIN based on predefined resolution logic.
  • This NXDOMAIN-driven re-routing mechanism helps ensure that services remain reachable to users despite backend changes.

 

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.
