Questions tagged [automation]

Automation is the process of building or integrating software that takes a manual or laborious task and brings it under machine control, thus reducing labour. Use this tag to describe questions that are about automation.

Automation is a key skill in the "DevOps Toolkit" by automating a process we are able to:

  • Increase throughput
  • Decrease toil
  • Reduce the incidence of errors

Automation is a part of DevOps but it is not the full story; when we automate a process we make it reliable and repeatable and thus we can run the process regularly.
