Most tools, frameworks and articles in IT, SaaS in particular, are about spinning up things. It is what people find exciting.
Work a few years in Ops and you learn that spinning up things is not a big part of your work. It's maintenance, such as deleting stuff.
Unfortunately this process is the hardest, and there's very little to help you do it right. Many tools, framework and vendors don't even have proper support for it.
Some even recommend 'rinse and repeat' instead of adjusting what you have - and this method is not great if you value uptime, nor if you have state that you want to preserve, such as customer data :-)
Deleting stuff, shutting services down, turning off servers - those are hard tasks in IT.
