Also, simple stuff like bandwidth is wildly overpriced with Vercel. My company switched away from all their magic image resizing stuff because as our traffic increased the bandwidth was 10x that of doing all media content through Prismic.
Vercel is hosted on AWS, and they're definitely not in the business of subsidizing AWS per-GB costs. Although the >2x markup is egregious ($40/100gb aka $0.40/gb over 1tb, versus AWS' $0.15/gb in its most expensive region, Sao Paulo, Brazil).
