Erlang

Hi Riteshh,

RE: Erlang Programming

Thanks for raising this question regarding Erlang.

The Erlang programming language is open source and has been around for over twenty years. It is a language that was first and foremost designed by Ericsson.

The language was created to replace the well proven Stored Program Control PLEX language that was used with the Ericsson’s Mobile and Wireline Products.

Erlang is a programming language used to build massively scaleable soft real-time systems with requirements on high availability. Erlang’s runtime system has built-in support for concurrency, distribution and fault tolerance.

Companies such as WhatsApp, Facebook Chat Backend,Klarna (electronic payment), numerous Universities, etc.. have solutions based on Erlang.

Reference:

erlang dot com (erlang.com)

Erlang Programming Language – Danish mathematician and engineer Agner Krarup Erlang and a syllabic abbreviation of “Ericsson Language.”

PLEX – Programming Language for Exchange (AXE10)

Erlang is very useful if you are attempting to solve the following technical architecture
issues:-

-Support a large number of concurrent processing requests
-High distribution over many Network nodes
-Rapid Application scaling. Well proven example is WhatsApp
-High end user interaction, i.e. responsive interation
-Continuous Application availability even during an Application upgrade

For sure other Languages can be used and this will be agreed with the
IT/Application Core Architecture team. An example is that a combination
of Elixir / Erlang can be used. Again, this will be a business / strategy decision.

For Instant Messaging chats you could use ejabberd – Erlang Jabber Daemon.

Reference:

Elixir is a dynamic, functional language designed for building scaleable and maintainable applications.

Elixir leverages the Erlang Virtual Machine (VM), known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in
web development and the embedded software domain.

Recommend that you look at Whatsapp URL.

There is a good white paper that describes the end to end security that the application uses.

whatsapp dot com / security.

You do not have to use WhatsApp. If the CSP supports Rich Communication Suite – RCS – then this can be used with your Smartphone.

Instead of waiting for the standards to be completed WhatsApp / WeChat / etc.. developed the OTT application so that it can be consumed. 3G / 4G / WiFi was in place and this helped with the adoption of WhatsApp.

You could even use WhatsApp as an IOT application.

For security please refer to the earlier Whitepaper reference.

Good if you can also highlight what you are trying to achieve with your different questions about Erlang, WhatsApp, Security, etc..

Hello
Can you write code of simple hello in er lang

Just a thought.

For your Application, you can look at GoLang. GoRoutine threads is designed for concurrency and alleviating “race” conditions.
