Spotify’s Love/Hate Relationship with DNS
Spotify has a history of loving “boring” technologies. It’s not that often people talk about DNS; when they do, it’s usually to complain, or when a major outage happens. Otherwise, DNS is initially set up – probably with a 3rd party provider – and then mostly forgotten about. But it’s because DNS is boring that we love it so much. It provides us with a stable and widely-known query interface, free caching, and service discovery.
This talk walks through how we have designed and currently manage our own DNS infrastructure, our curious ways in which we use DNS, and the future of boring technology at Spotify.
