That's something I find so fascinating. The "cloud" will almost always be more expensive and "not worth it" if you are only using the IaaS services. I mean, look at the numbers, everyone sees that.
Cloud only ever is worth it when one uses the higher-tier services, like AWS Lambda and the likes.
Even running Kubernetes in the cloud is only semi worth it, because it's not high enough in the stack and still touches too many low-level IaaS services.
Of course, higher tier means more vendor lock-in and more knowledge required and all that. But if you are not willing to pay that price, then OVH, Hetzner and the likes will have better offerings for you.
