> HAProxy 2.2 for terminating TLS connections, and load balancing between app servers. Enables easy rolling updates of application servers.

Wonder why he is not using hetzner's load balancer [1]. At least cost-wise, the savings are huge (4xAX41-NVME are around 160€; LB31 - the most expensive one - is 36€)

That product has a serious lack of docs, and I know from experience some off-cloud vendor balancers have crappy architectures with low overall throughput limits. Their product could be a shared CPU VPS under the hood or something deeply baked into their network architecture, guilty until proven innocent

The load balancer is at the core of the product reliability. That seems a good reason to completely control it instead of relying on a black box.

It's kind of interesting that there's more horsepower/cores in the load balancers than in the downstream web/app servers...4xAX41 vs 3xAX41. So I imagine something is different about the workload there versus a typical load balancer.

I believe the load balancer is pretty new and it is probably the only service that allows connecting to dedicated servers -- which is separate from their cloud offering.

Hetzner's LB doesn't really scale. LB31 should be based on CX31 which is just 2 vCPU compared to the 12 threads of a single AX41 dedicated server.

i tried to use it out of curiosity but the documentation was really lacking and the workflow of creating the networks is bad
