Containers, k8s (or k3s, because less bloat) and micro-SOA (but preferably in a monorepo) make development easier.
Overdoing the infra-HA-magic is bad, of course. But if you use containers, you can spin up dev envs faster, devs can just docker-compose (I still recommend Vagrant + docker, so devs can use whatever OS they like), and it helps with config management a bit too. (Much easier testing, deployment and upgrades.)
That said paying for AWS is the worst idea ever, it's so overpriced and the most used servie is EC2, which people could get anywhere else. (Sure, there are probably nice tricks that this pony can do, but there's probably a whole cottage industry trying to copy their niche offerings.)
