In-House vs. Outsourced DNS

  1. 1. WHAT'S THE DIFFERENCE IN- HOUSEDNS OUTSOURCEDDNS An in-house server or rack that hosts an organization's query traffic A third-party provider that routes traffic on a global network WHICH IS THE ONE FOR YOU? In-house systems are costly to set-up, and there are dozens of other costs to keep users online: DNS providers don't charge set-up fees, and you don't have to spend more for greater infra- structure. Just one low monthly fee Software Bandwidth IT staff Maintenance And then there are security costs like firewalls & individual server conf- igurations BUT THIS STUFF DOESN'T EVEN MATTER! If the in- house system gets flooded by an attack or too many visitors, it will be knocked offline before the traffic even reaches the firewalls In-house systems use Unicast networks That means they operate out of one location It also means there's a single point of failure DNS providers use IP Anycast networks which contain many geographically unique Points of Presence (PoP) Each PoP has dozens of name servers, each exponentially increases layers of redundancy FAIL Resolution times are faster because the name servers are closer to the querying clients
