I'm a web developer for an ad agency. We are looking to use Moodle to produce a course for representatives in many different time zones, currently there are 17000 but will be up to 30000 they will only be taking once lesson at the moment, possibly more later.
I will probably use a VPS with 4gb of dedicated ram. Is that enough for this amount of users or would one 4gb server instance with 4gb of ram for the Moodle install and one 4gb server instance for the database be necessary.
The second item I need to know. we will be making the course lesson with Adobe Captivate 5, can Moodle out of the box keep scoring and success stats and tell the student they have successfully completed a lesson or do i need additional software?
