Authentication on Level 4 Load Balancer - What options are there?
I´ve stumbled across Digital Ocean and it´s managed Kubernetes Cluster and I´m pretty happy with it, except the lack of an API Gateway that provides authentication out of the box.
In order to get my MVP up and running, I´d love to keep costs as low as possible. That implies having the least amount of pods running as possible which is one of the reasons I don´t want to do authentication on my Ingress Controller besides the complexity and maintenance costs, and I also don´t want unauthenticated requests to eat up resources of my cluster.
What managed solutions are there to do authentication on Layer 4? There is APIGee which is expensive (I guess - no public pricing information) and cloud platforms such as AWS or Google Cloud do not allow to use their API Gateways outside of their platform
