Webinar – DNS High-Availability Tools – Open-Source Load Balancing Solutions

The DNS protocol has built-in high availability for authoritative DNS servers (this will be better explained in the webinar!), but client machines can see a degraded DNS service if a DNS resolver (caching DNS server) is failing.

In this webinar, we look into how the DNS clients in popular operating systems (Windows, Linux, macOS/iOS) choose the DNS resolver among a list of available servers, and how a DNS resolver service can be made failure-tolerant with open-source solutions such as “dnsdist” from PowerDNS and “relayd” from OpenBSD.
