      4. Our team who run it are TLS/SSL experts. Folks who've contributed to the RFC. Folks who are clued in on the latest protocol attacks. They are also scale and operational experts. The team started as the front-end team for Amazon S3, and now manage nearly every AWS front end.

      5. NLB's TLS support integrates with Amazon Certificate Manager; we can automatically rotate, replace, and revoke certificates. No more outages because of an expired certificate!

      6. We have access logs, and can tell you about your TLS clients! We log things like the cipher suite and protocol version used, which makes it easy to audit if it's safe to disable an old algorithm.

      7. NLB's TLS support can still use TLS to your targets, so you still get TLS traffic all the way to your target. This might seem strange, if you're going to run TLS on your own end anyway, what's the point?

      ... well, NLB runs on Amazon VPC. On VPC we encapsulate, authenticate and secure traffic at the packet level. Packets can't be spoofed or MITMd on VPC. Traffic only goes where you send it. That makes it possible to use a self-signed, or even expired, certificate on your end.

      In TLS/SSL, certificates are just about authenticating the server or the client, but since Amazon VPC does that at the packet level, you can offload the problems that comes with certificate management to us.

      8. You can run plaintext too. I wouldn't recommend it, but you can also use NLB TLS as a total TLS/SSL off-loader; you can run plain TCP to your targets and NLB will translate between TLS to/from your clients and TCP to/from you. We *still* preserve the source IP, even then.

      9. If you've been using our Classic Load Balancer as a L4 load balancer with support for TLS, you can now move to NLB!

      That's it from me! You can start using it right now, I've had a test NLB going for a few weeks myself. Super super delighted to get this out there. AMA and let me know if you have any suggestions or questions! EOF.

      On the AMA side, does it or will it preserve source IPs across PrivateLink services shared across accounts?

      Nope! an NLB as part of privatelink doesn't preserve the source IP. That's because many source VPCs can have overlapping ranges, so it wouldn't disambiguate the traffic. Instead we send a ProxyProtocolV2 header with an extension that indicates the source ip/port and origin VPC.
