Erlang



  • Easy and Scalable

  • Mature soft real-time

  • Cluster orchestration

Messaging, DHT


Enterprise


Haskell 1998 — mostly academic

OCaml 1996 — marginal classic

Scala 2004 — Java replacement

Erlang 1986 — most enterprise-like



Erlang — Dynamically Typed Functional Language


Don't be sad, Look on numbers...



MQ



    • FioranoMQ JMS

    • Tibco JMS

    • WebSphere JMS

    • RabbitMQ AMQP




MQ server — cluster heart. On of the most scalable and fast MQ — RabbitMQ — AMQP implementation of messaging protocol developed in JP Morgan.


KV


C/C++:  Redis AP, MongoDB AP

Java:     Oracle Cache Coherence AP,

               Cassandra CA, Hadoop CA

Erlang: Riak AP, CouchDB AP, Hibari AP,

               KAI AP, LeoFS AP, Mnesia CA


Erlang has more DHT implementation

than any other language 

because of its cluster ready infrastructure.
