Are you saying Erlang is as successful as rails, node or django?

The notion of success is quite relative anyway when it comes to subjective things.

Comparing to PHP Rails is an enormous success, but comparing to J2EE it still has something to catch up.

As for node, I doubt that it is a "success". For me it is just a product of Javascript "sectarian hype" along with cumbersome design decisions.)

The principles and desing decisions behind Erlang are well-researched and "robust". Details are in armstrong-thesis-2003.pdf

That's interesting. To me, J2EE is a pic failure in turns of developer enthusiasm (might be considered successful because of usage). I am yet to meet a developer who likes to code in J2EE and they would take every opportunity to jump ship to just about anything. That said, mine is a startup world and nobody I know writes new code in J2EE.

It controls serving of probably more than 50% of world smartphone to internet data traffic. That is pretty successful.

It handles tens of billions of messages per day for Whatsapp, that is successful.

Riak and RabbitMQ handle a lot of data and messages for many companies.

Ejabberd and derivatives are probably the default enterprise chat/XMPP backends.

If anything one can argue it is more successful than any of those technologies.

What are node's success stories? Paypal, Walmart, New York times. I haven't been following but those are ones I remember using it.

I have nothing against Erlang. Good for erlang if its successful. I wonder why then I see AOL these defensive posts about why Erlang has not been adopted enough
