Keeping operating modes simple is something that pays off especially in large scale systems (let alone smaller ones): https://archive.is/2S2ME (Doing Constant Work, Colm MacCárthaigh, AWS Builders' Library).

Generally, I've found that, in the guise of doing the simplest thing, I've done the most naive-est thing possible, which unfortunately comes with the burden of tech debt. So, as a rule of thumb, given the small tech shop we are, I tend to favour systems that are fully-managed or serverless and prefer to take on whatever tech debt using it throws at me.
