Rainer, there is no simple thing like "DDoS" protection.

You need to plan what ddos are you going to handle, because if you get 5
gbit/s of SYN flood, it doesn't matter what language for your website do
you choose, it matter what ddos protection service do you choose.

For example, if you are under serious ddos attack, you have only one
choice: go to company that have control over it's AS connectivity and at
least 100-200 gbit/s of connectivity and ask them for a protection. They
will give you new IP address of a proxy.  This proxy will filter about
99,99% of traffic and leave only valuable requests. So again: it doesn't
matter what language do you choose.

But of course there are serious design ideas that make erlang much superior
comparing to node.js or even Java. It is process+messaging model.
