I am building a user generated multisite and do not have significant control over the rate of growth or the size of the overall network. If the day comes that a 1,000 new sites are generated by our users we want to be ready.
I see that Amazon Web Service and Google App Engine might be good solutions. I am wondering what are the disadvantages here? What type of additional tasks will I need to take on with these options over the run of a mill hosting provider on VPS or dedicated?
