I've seen several job postings requiring 10 years' experience with the cloud platform I work with. It released in 2015.

I always go by the "75% rule" - if I meet 75% of requirements they ask for, I apply. You never know who actually wrote and contributed to the posting. The requirements can be far removed from what the hiring manager actually cares about.
