Re: [EXTERNAL] AW: IBM i 7.6 Development tools

IMHO for ERP like enterprise based systems (production processes, accounting, high precision and throughput WMS..), native horizontal distributed systems are just needless complexity.
Those are different beasts and different requirements than the approach required to build - say - a netfl1x of gm@il ... things that couldn't have been built with central architectures, no options there, but horses for for courses... Those technologies obviously gain a lot of investment and momentum and economics and then are applied outside their original domain (i.e. see "the web", once a simple stateless document retrieval system, now the world is all-over-http, a pretty inefficient, verbose string based protocol and CPU cycle wasting galore, with pillars of strata and sessions states emulated on it...).

Today we can have - in a single machine - tens of gigabits of network, hundreds of cores in single instances... performance is not the problem (and thus to use it we need VM, then para light VM, then containers, then microcontainers, the micro stuff to coordinated all that,  then light lambda functions.... then... then... *PGM and subsystems going full circle ;-PPP ).

document based mongo and cassandra again nice tech, born in distributed environments meant to solve diffent problems.... usually in ERPs a single process can be informed by hundreds of fields in different structure, rarely one has "one view / one path" centrism to organize the data (paradoxically such systems crystallize in some sense structure to cater for easy distribution).

Not improving the 5250 and creating something incremental OS NATIVELY (not only OA, but a richer stack... known by everybody like DDS then) over it was - at the cost of being tediously trite - of course a big mistake, because it is basically, let's be honest, the only thing that limit the system in the stock form.
