HTTP2 over AWS ELB under TCP Mode

Does anyone have the experience using HTTP2 server behind AWS ELB running in TCP Mode?

As I know, AWS ELB does not support HTTP2 now, however, by using TCP mode, it should pass the request to the backend server transparently.

Does someone have the experience for sharing?

Thank you.

Supposedly the new Application Load Balancer supports HTTP/2. I'm a little unclear whether it's useful, however, if CloudFront doesn't support it yet: https://aws.amazon.com/blogs/aws/new-aws-application-load-balancer/

ELB has no way of pipelining connections. Therefore you cannot trick it into do http2. Maybe with the new version coming out, but not sure.

Yes, TCP port 443 works to bypass ELB's HTTPS, but there's no way to do session stickiness since ELB can't read the cookies over the wire.

You may also consider using h2c (HTTP/2 over cleartext).
