Processing web requests & some reports, pretty much the same as everyone do nowdays. Dev team add some features, but still on scale it the same - web requests and reports.
CPU is pretty much idling, like ~ 10-15% used on average, in spikes may be 20%. But that's minimal CPU hoster gives with RAM 128GB+ platform, so using it.
RAM (~ 110GB) obviously used for DB and the for auxilary tasks.
DB itself is medium sized, with raw data ~ 1.5TB yet
DISK IO on average is pretty high, around 55%, with often spikes to 100%, that part I'd add more IOPS on if response times grow above the limits.
