The Excess Capacity Myth Debunked
The popular story that AWS began by renting out Amazon.com's idle Q1-Q3 server capacity is shown to be technically and financially implausible, confirmed false by Werner Vogels himself.
- Pre-cloud infrastructure was tightly coupled and not easily shareable across tenants
- AWS customer demand would conflict directly with Amazon's own Q4 holiday capacity needs
- Werner Vogels publicly confirmed the excess-capacity story is a myth
“the excess capacity story is a myth it was never a matter of selling access capacity”
“amazon web services was always considered a business by itself with the expectation that it could even grow as big as the amazon.com retail operation”
