Sure. I consider myself a fairly good dev. Not an amazing genius or anything but pretty competent in my area. Wouldn't have a clue how a load balancer works beyond what's in the name, I guess it balances loads. I can assume it does this by distributing requests to different servers because that just makes sense, but I don't even really know that. Networking might as well be black magic as far as I'm concerned. I'm grateful we have a decent infra team who knows about all that. So I'm not surprised.
