The best part of bootiful is that it's free for testing purposes! I am using this service as my first step towards creating applications which are scalable/maintainable at large scale (i'm talking about millions+ users).
So far so good - everything works fine but i have some doubts regarding security aspects like logging into account etc., maybe they can be improved or something may not work properly sometimes because we're just starting out :) We haven't found any problems yet though when dealing solely within our own environment; however there might come up issues related only eith other organizations' environments since all data will go through their servers anyway by default. Also you need someone who has experience managing databases such MySQL & PostgresSQL DBs before implementing them yourself otherwise things could get very messy later down-the line :D.
