The Lost Generation discovers IBM Mainframe Channel Programs?

Want to bet if they are going to make all the same mistakes themselves, or if they are willing to learn from history?

Seems like they only resemble Channel Programs in spirit since they don't use any specialized hardware. If it all runs on commodity hardware and is completely generic/customizable in software then it seems a lot more useful and economical than anything for a mainframe.

All snark aside, is there potential benefit to Varnish Cache with this becoming widely adopted? Things that could only be accomplished at lower layers like this implies access to?

Since there is already highly efficient event driven I/O and a context switch is bound to happen for applications that require major business logic in user space, I doubt there will be huge benefits for large server applications.

Maybe simplified versions work with this paradigm with significant performance gains, but I doubt that you could simply plug Varnish or nginx in and see much of an improvement.

There is still quite a complexity gap between e.g. interpreting firewall filter rules and a full blown web reverse proxy..

I think you could use this to generate a reverse proxy for the current config in nginx, maybe if only for some subset of configurations. Like a fast path for common flows. But it wouldn't be easy.

Enlighten us grey one.

Which mistakes? Like, I've def got a few in mind, but I'd like to hear your perspective.
