Some time ago I got seriously interested in Erlang (coming from C++/PHP/Java world) - and I've seen it has been successfuly used in the industry, by Ericsson, Facebook, Goldman Sachs, etc. So, I thought it would be a great platform to build high demanding apps, with low-latency profile, with a lot cleaner and nicer language than, for example, Java (for me).
But after "wow effect" has gone, I discovered that there are many high performance Java libraries that seem to resolve many problems that Erlang is theoretically best suited for (real-time, low-latency applications, concurrency, fault-tolerance, etc.). Moreover, it seems that there are things that, despite Erlang profile, are just not possible to achieve on BEAM (like LMAX Disruptor concurrent framework).
So the question arises: is Erlang still the best platform to build such demanding applications ? Wouldn't it be better if we stick to one, very mature (J)VM and try to make it even better than trying to achieve something similar with less resources available (size of OTP team vs. JVM team, supporters, etc) ? And is it possible at all to achieve this kind of performance and adoption with BEAM ?
And just to make things clear: I don't want to init a flame war here. I am just curious because I really like Erlang and I think it's a great platform and I'd like to invest time and effort to build real-life projects on it. But I'd just like to know what others might say about that and - if I am wrong - maybe someone could correct me.
