Infrastructure as Code is powerful; Terraform + k8s (with nginx-ingress/cert-manager/external-dns) and you never need to worry about infrastructure again...
They are listed in the ascending order of how many problems they cause, and how much we have to worry about them ... I will never ever touch K8s if I can possibly avoid it.
At my last job, heroku was the cause of at least an outage a month. The redis add-on was particularly troublesome, as I recall.
That's not to say the rest aren't bad, of course, but I'd much rather have control in my hands than wondering if the next time it goes down again how many angry phone calls we'll get and if there is even anything we can do about it.
Give me a few bare servers any day, but you take what you can get I guess.
Yeah, until your team starts using PaaS services and your terraform modules are a mess that barely supports a third of the product's configuration, and that process is going to accelerate more and more over time.
Problems that most devs wish that they had but don't.
