please explain how to get high capacity architectures with both the default asp.net web forms and mvc models with regard to being able to serve millions of page views.
i want to know how to set up each model from DB clustering, to caching, logical/ physical tiers, load balancing iis servers, scaling out or up, session state management and so on...
is one more scalable than the other?
There is no one answer. A good option is to check the architectures for some respected Open source projects to see what other people are doing.
