Suitability for piloting (or permanent) external high-volume Web Apps

Mendix seems great, but what do you think about suitability for creating consumer webpages. - Demanding rich UI - lots of anonymous users, some of them creates user accounts on a self service basis. and Will the subscricption model be very expensive for thar usage pattern (many hits, many users)?

Not pretending being complete my humble opinion:

Mendix can be be used for high-volume web apps but it needs heavy hardware and optimization to get that working. It was not designed for that purpose. A custom written lower-level language site will win on performance but not on implementation time and costs. It depends on the requirements.

Self service can be done in Mendix.

Rich UI: you have to define that, but prepare to write widgets.

You can negotiate prices.
