hub vs. server?

[KlavsKlavsen]

What is selenium server vs. selenium hub?

I would like to have my main server - containg whatever is necessary - so I can add extra nodes alter on (windows nodes for IE f.ex.).. the readme doesn't seem to make it clear, what I should choose :( - and explicitly says that ::hub and ::server conflicts - as they use the same port by default..

Selenium server is a stand alone application for using a single server as a test node. Selenium hub acts as a proxy in front of one or more Selenium node instances. A hub + node(s) is called a Selenium grid. Running Selenium server is similar to creating a Selenium grid from a hub and a single node on the same host. I highly recommend reading the Selenium documentation to help determine what the best approach for your usage case(s) is.
