MySQL'a dual licensing has been the source of a lot of confusion for
quite a long time, and what few notes can be found at their site about
when their license requires a license doesn't help a great many people
make an appropriate determination.
I've written them to get clarification on three specific usage scenarios
that are not uncommon, and while their sales staff was quick to reply to
my interest in possibly getting a license I've not heard back from them
on whether it's actually needed in the scenarios I'm considering.
Here's an example of the confusion, from JoelOnSoftware:
This comment there tries to help sort it out:
Most of the things mentioned here are irrelevant.
"If you develop and distribute a commercial application and
as part of utilizing your application, the end-user must
download a copy of MySQL; for each derivative work, you (or,
in some cases, your end-user) need a commercial license for
the MySQL server and/or MySQL client libraries."
Unfortunately that URL no longer points to the material cited, so you
have to wade through the links there to try to find guidance on how the
license applies to a given use.
Here's a scenario I can't figure out: if I make a DB on my server using
my own proprietary code running on top of MySQL, and I sell
subscriptions to this proprietary system, do the "per seat" definitions
for MySQL licensing apply to my customers as "seats" for my DB use?
Still waiting to hear back from them on that.
It's too bad they don't make it simpler for folks to understand when
it's necessary to purchase a license and how much it will cost. It's
confusing for the market and no doubt they lose a great many sales based
on the near-ubiquitous -- if erroneous -- presumption that it's always
gratis. Free as in freedom != free as in beer. ;)
Ruslan, I couldn't find the original post you quoted. Where did this
