sql server replication: Hello there

I have one server that recive data, and 1 or more servers who just
presenting the data.

From my knowlage there are two way to do that:
1. transactional replication,
2. Windows clustring.

I'm wondering which one of them are better.

Roy,
clustering isn't a way of distributed processing or load balancing so I
wouldn't include it here.
I'd look at transactional replication vs log shipping (see here
http://www.replicationanswers.com/Standby.asp) vs database mirroring with
database snapshots.

It's more of a front-end thing. It allows there to be > 1 website to access
the backend. However the data still exists in one place so backend processing
is not distributed.

Use transactional replication. Transactional replication can be used in NLB
environments where all the web servers which form the front end of your NLB
servers hang off a single SQL Server, or they each have their own SQL
Server. Replication can keep all these servers in sync.

Whell Hilary.

Thw web application is quite huge. In fact there are 2 layers in that area,
Business and presntation. Today they are in diffrent server and use windows
clustering to improve performance.

If I will do what you offered about placing sql server asubscriber at the
business server, will it reduce performance because the same server has to
manage sql server and business layer together?
