Thanks for the info and pointer to a potential solution.

I started by looking at how to install it and landed at 
https://mariadb.com/kb/en/mariadb-package-repository-setup-and-usage/

That tells me "MariaDB MaxScale is licensed under the Business Source License 
1.1, so it is not entirely free to use for organizations who do not have a 
subscription with MariaDB Corporation. If you would like more information, see 
the information at MariaDB Business Source License (BSL): Frequently Asked 
Questions."

So, I'm now trying to understand the licensing limitations of MaxScale - since 
it's not simply GPL like MariaDB is :(

Looking at https://mariadb.com/bsl-faq-mariadb/ it talks about usage "below 
the specified use limitation".

Then referring to https://mariadb.com/projects-using-bsl-11/ I see:

"Additional Use Grant: You may use the Licensed Work when your application 
uses the Licensed Work with a total of less than three server instances for 
any purpose."

So, is this "additional use grant" the same as "usage below the specified use 
limitation"?

Also, does "less than three" mean "one or two" or does it include "three"?


Finally, assuming we want to use MaxScale in a production environment with not 
"less than three" instances, where can I find the price list telling us what 
this would cost?


Thanks,


Antony.
