Eric:
I would be with Anne and disagree with the
statement below, Amazon is in the retailing business and not “selling”
software but using technology to allow people to access and utilize its primary
service – retailing goods.
The same would be in the case of eBay
whose primary service is the collaboration platform and not in the software
business.

[service-orientated-architecture] SAAS vs SOA
Hi Anne,
Wouldn't Amazon.com (or Ebay) be a case of a
company
that is not a software vendor but that is still
selling software as a service? And using
services as
the enabling technology to do so?
