IBM AS/400: Databases all the way down (2019) [video]
I like to joke there are platforms that were so ahead of their time they are still ahead of ours. The AS/400 is one such thing. It concerns me IBM doesn't seem to provide enough entry-level resources (and I believe nobody would do a green field project on IBMi that required a company to invest on the platform unless it already had a sizeable investment on it). For all three of their crown jewels, AIX, Z and i, IBM is doing a terrible job in onboarding new clients.BTW, I've been trying to set up a small AIX box to do some software testing (and not make the mistake of making a Unix app dependent on linuxisms) on IBM cloud and, even when you navigate the confusing UI and metaphors (there is no "give me a POWER10 AIX VM with this many vCPUS, this much memory and this much disk" option), it's failing for me for unfathomable reasons while trying to create a storage volume with the default options. On a side note, I can create a Linux VM running on s390x from the same flow I create x86 ones, but I can't select a z/OS disk image, or a POWER processor. If I want a z/OS machine, I have to go through an entirely different workflow (one I went through, only to never be able to figure out the IP addresses I could ssh to).
