Cloud and Data platform have common needs as dev platforms, but there are challenges that are unique to each area.
E.g often orgs are dealing with multiple cloud platforms over time, and rationalization could show clear ROI numbers
Maybe Data platform could cover needs from ML/AI Platforms as well.
Dev for sure cover a big chunk of the pie but will be great if someone could write an article covering Cloud & Data. Mostly the ROI spreadsheet will be significantly different.
Your article is great because I saw this pattern multiple times across orgs:
Limited ability to demonstrate with numbers, how they can invest/rationalize in order to get the ROI savings later.
