In my experience, people are using k8s et al and microservices because "everyone is doing it", "nobody got fired for choosing microservices", "I need more cloud stuff on my resume" and a vague (and unsubstantiated, unless you're in SF maybe) hope to hire ops staff on the cheap. Frequently, it ends up in a mix of a partial k8s setup for services plus dedicated DB, logging, backup, and other proprietary persistence infrastructure services. In other words, the union of problems/risks, and the intersection of capabilities; and in particular such that moving to another cloud provider is impossible :)

Cloud services is pretty much a business of huge marketing budgets and old-school lock-in strategies.
