DNS

Meaning in cloud computing & devops, with examples

abbreviationCore term

In cloud computing & devops, DNS means: Short for Domain Name System: the internet's directory that turns names like example.com into the IP addresses computers use to connect.

In Turkish: alan adı sistemi, DNS

How it is used

Engineers create and update DNS records (A, CNAME, TXT, MX). A record's TTL controls how long others cache it, so changes can take time to spread. Engineers joke 'It's always DNS' because so many outages come from it.

Example sentences

  1. The new site isn't loading for some users because the DNS change hasn't reached their resolver yet.

  2. Lower the DNS TTL a day before the migration so we can switch quickly.
