**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 76 answers here cite 1,047 pages; the sites cited most are cloudzero.com, cloudaware.com, amnic.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
