I use k8s with load balancer and feature of my project - is a development/staging temporary environment per every user that uses my project. For every user, I am run pod with ssh,MySQL/mongo,rabbit or another tcp/udp external ports. I am proxying these ports with ConfigMap k8s component helpful, but I limited diigitalocean limits(40 ports) and I am can't scale my project because LoadBalancer is my bottleneck...
I suggest make LoadBalancer limit - dynamic, and make different price plans with different limits per each plan(i think about plans from 40 proxy ports count limit till 500 or more)
New feature with a high perfomance load balancer "Large $60/month", also doesn't cover this issue... Maximum ports forwarding rules also still is 40 for all LB types
