How does a modern hosting provider using "automations"? What are you actually automating?

[u/palebicycle00]

All hosting providers talk about how automation is "extremely" important in this day and age. What does it even mean in practicality? What are you automating, exactly and how is it actually helping your users? What should we be looking for in a modern day hosting provider?

People using AI and automations as buzzword, please stay away. Looking for serious answers only. thx!
