I'm not really clear on how moving off Kubernetes saves you money in this scenario. Seems like the most likely source of the cost is the AWS, which is the non-free part. I'm just learning k8s, so I feel you on the learning curve.

Kubernetes has a minimum node count.
Moving to one node, saves cost, by a factor of 3. Not to mention all of the other resources it creates (load balancers).
The largest reason is cost. My small deployment (3 nodes) is running around $100 / mo on AWS (That's my app, nginx, redis, and postgres).
It doesn't even need 3 nodes, I don't recall if 3 is the minimum, but realistically I only need one (for now). For larger projects this is probably a non-issue.
Second largest reason, is that really I have no idea what is going on on these nodes, and I probably never will. Magically my services run when I have the correct configurations. Not to say that's always a bad thing, but I've found it difficult to determine the default level of security as a result of this.
A third reason is the learning curve. This is less of an issue because I've invested the time to learn already. But like, the first time I tried to get traffic ingressed was painful.
As to what I'm moving to, I migrated one of my websites to a simple rsync + docker-compose setup and am pretty happy with it. In the past, I ran ansible on a 50 node cluster and it worked really well.
