Any Dogfood Is Food Enough
I've been in IT for 30+ years and I've seen dozens of examples of IT companies preaching one thing to the outside world and doing another thing - including "do nothing" - inside. In the mid-1990s, Sun Microsystems was big, created paradigm shift in computing from old mainframe to new client-server architecture, but, for its internal order management system, it used an IBM mainframe! Microsoft has been using SAP ERP since circa 1998 that I know of. At the time, Internet and Intranet were going mainstream and enterprises were in the early stages of extending their applications to end users in self-service mode. Microsoft wanted all its sales and marketing employees to access a certain product / pricing-related functionality processed on SAP. The SOP was to buy licenses for all these folks but, since they numbered in thousands, extending SAP to them would have cost the company tens of millions of dollars. While that was peanuts for Microsoft, we know from history that people with modest means don't have a monopoly over nickel-and-diming. Accordingly, Microsoft allegedly built a frontend in VB and used it to access the information from the SAP backend periodicially and distribute it to the end users. Said VB app counted as just one extra user license of SAP. SAP threatened to sue Microsoft for violation of its EULA by replacing thousands of user licenses with just one. Microsoft countered back, saying it was making very innovative use of Remote Job Execution technology. Memory serves, the lawsuit was settled before it went to / out of court - hopefully for an amount, including lawyers' fees, that was less than the 10s of $M price quoted by SAP for those additional SAP user licenses.
