In 1998 I worked for a small nasdaq company that had a successful software as a service product that was growing quickly.

We used Clarion and MSSQL7 on windows because it was cheap. Since we started making real money, some figured we could finally afford Oracle and Sun (back when they were different).

I was a junior so my job was to evaluate the migration of one of our sql servers to oracle to test it out. I talks with the Oracle team who helps people plan purchases. They took my transaction level (~100M/year) and size (1-2GB/year) and came back with $1M for the system. This replaced a functioning $10k server. And we had maybe a dozen that would have to eventually move.

When I told them the current server was $10k, they revised their estimate to $100k. I recommended we not move.

I left the company a little while later and I think they ended up buying lots of Oracle.

Companies have money and don’t mind spending on useless stuff.
