Aws is closer to monopoly than to utility

[groundzeros2015]

A monopoly with at least 3 major competitors and which exists because it created a new thing, not because it controls a fixed shared resources.

[monocasa]

Most utilities are monopolies.

[bluGill]

most utilities are natural monopolies. The cost to run wires/pipes to my house are a significant portion of the cost to serving me, so you wouldn't run wires to my house in hopes that I buy from you later.
