Also, haproxy is one of the most reliable software I've ever used.
I wouldn't call it the best way; Rather a good way because Kubernetes does encapsulate the really good bits from scalability, development, security and reliability aspect. It's not a panacea but if you have team bandwidth to run k8s cluster, it's definitely worth a look.
<3 HAProxy. It's a solid piece of software tested to the teeth over the years and is great; Here's the thing: You can run it as your preferred ingress controller too :) https://www.haproxy.com/blog/dissecting-the-haproxy-kubernet...
