Hi all!
Thank you very much for the replys, all util information for my decisions.

As Chris noted:
- My first post need to be fine tuned. Until next monday
I will post the answers for the three questions (actual hardware, app type
and access peak/average relation).
- I`m most interested in knowing whether or not a Rails equivalent to
current ASP application (and the new app that will be developted) will be
capable of running on the same hardware and infrastructure as my
existing setup with approximately the same resource requirements and
performance.

For now, I can make only a little fine tune: I said one milion pageviews,
but it is not exact, because 50% of the pageviews are consumed by the
forum, and the new rails site won`t include the forum, rather we will
use Vbulletin or Jive SBS. Also, the rest 50% pageviews are consumed partially
by static content.

Regarding hardware, I already use slicehost for some projects and like it.
I`am thinking about to use 2GB slice:

Plan RAM Storage BW Monthly Cost
2GB slice 2048MB 80GB 800GB $130
from http://www.slicehost.com/

Of course, it is just a possibility, since this decision depends strongly of the
research I`m doing now (including your replys).

Hi Tom,

Just to fine tune your original question, you're probably most interested in knowing whether or not a Rails equivalent to your current ASP application will be capable of running on the same hardware and infrastructure as your existing setup with approximately the same resource requirements and performance.  If I were sitting down with you as a consultant, I would immediately ask the following questions:
  • What does your current hardware and infrastructure solution look like?  (i.e. number and type of servers, where hosted, etc.)
  • What does your application look like?  (i.e. mostly static content, dynamic application functionality, little/lots of Ajax, etc.)
  • How much higher is your peak load than your average load?  (i.e. 10x, 50x, 100x, etc.)
Without that information, you're going to get a lot of answers about how Rails scales well without really knowing whether or not Rails will scale well for you.  However, if we assume a peak load somewhere between 10x and 20x, you're talking about something on the order of a few hundred requests per minute which is not such a high demand to place on a basic Rails app running on a single recent model server, especially if you're able to implement some form of caching.
