Why is there no middleware in Erlang?

Question

I asked a question earlier about ESBs written in Erlang or Java, and there didn't seem to be anything in Erlang, and only products in Java.

I guess I find it difficult to understand why a language like Erlang has no such middleware products, especially seeing as it should be ideally suited to the job.

Update: There are in fact "some" middleware products for Erlang:

@aChristian suggested RabbitMq

Also, Erlang does have middleware, in fact it is a standard part of the Erlang distribution. It is called OTP.

Answer 1

Probably because a lot more people use Java, especially those people who write middleware products. As in "For every Erlang programmer, there are 300 Java programmers".

Answer 2

ESBs are used by large companies (E is Enterprise in ESB). Large companies tend to prefer the nr1 technology/vendor/consultancy company to reduce risk. See also "No one ever got fired for choosing IBM"
