If you're curious to see NLB in action, here's a live demo: http://nlb-34dc3b430638dc3e.elb.us-west-2.amazonaws.com/ , it took about 5 minutes in the console to set it up and no changes on the targets/backends. Massive disclaimer: I work on NLB.

Is there any intent to add TLS termination? That’s a dealbreaker for us switching from the classic load balancer. Otherwise this looks really awesome, thanks!

Awesome! I have the perfect project for this haha. Does it still work with ECS integration?

Yes it does ( target group integration )

Happy to be educated. There's some easy way to alter the destination IP that way?

Like mention above IPVS: http://www.linuxvirtualserver.org/VS-IPTunneling.html This is heavily used by Facebook for their loadblancer on their racks.

Ah, ok. A kernel module, as I mentioned :)

I don't think they can add TLS termination because of the way it's implemented. NLB runs on Layer 4 - the transport layer where TCP/UDP run on. TLS technically runs on top of the transport layer.

Are there any plans to add UDP support?

This was discussed a couple of times recently, but answers seemed contradictory. ELB requires pre-warming if you expect sudden high load. But do ALB and NLB? [1] https://news.ycombinator.com/item?id=15085863 [2] https://news.ycombinator.com/item?id=14052079

Each NLB starts out with several gigabits of capacity per availability zone, and it scales horizontally from there (theoretically to Terabits). That's more capacity than many of the busiest web-sites and web-services in the world need. If you expect an instantaneous load of more than about 5Gbit/sec, in those situations we work directly with customers via AWS Support. We really try to understand the load, make sure t…

This is painful, though. I don't know about Sep 2017, but in 2016 upscaling your ELB involved answering a block of 21 or so questions in a list only given to you after you engage with support, which had some pretty esoteric items on it. It was decidedly un-AWS-ey.

This would be great to have.

Huh? It's no different than ELB.

Does NLB have the option for session affinity? i.e. keep the same tcp connection open to the same backend host?
