Erlang development

Erlang is a functional programming language with strong dynamic typing. The language is perfect for developing distributed computing systems.


Features of Outsource Erlang Development


High-level language constructions

Erlang is a declarative programming language that allows describing what should be computed instead of describing how it should be computed. Erlang development outsourcing offers the use of dynamic typing, which can speed up the application development.


Parallel processing and transferring of messages

Erlang processes are lightweight (the process creation time takes a few microseconds and does not depend on the number of running processes) and even more efficient than the operating system threads, enabling Erlang to work with several tens of thousands of processes in the same app.


Distributed processing

Since Erlang processes do not use shared memory and communicate only through messages, the language easily turns a parallel app into a distributed one, where different processes are executed on different network nodes.



Erlang supports various approaches for building highly reliable systems. At a lower level, the processes can be linked together and alerted by messages upon completion of the linked process. At a higher level, with OTP, it is possible to set different policies for monitoring individual processes and process groups.


Soft real-time operation

Erlang uses automatic memory management, where “garbage collection” is performed separately for each process in the system. Hire an Erlang developer to make your system respond within a few microseconds, even with garbage collection, enabling operation at a high load with almost no loss of performance.


Operation of apps for a long time

Erlang supports “hot” code replacement of modules in a running app, in which the old and new versions of the code can run at the same time. You can address this with an  Erlang development company, if your system should not stop to update the code. The examples of these systems include telephone systems or traffic control systems.

Projects using Erlang


Erlang was used for creation of SimpleDB, which provides a storage service for Amazon Elastic Compute Cloud (EC2).


Erlang was used to create Delicious, a social bookmarking service from Yahoo! with more than five million registered users and more than 150 million bookmarks.


FB used Erlang to create a chat service serving more than 100 million active users.


Ejabberd, an instant messaging service with the use of XMPP protocol, is written in Erlang.

Erlang was developed and maintained by Ericsson in 1987 for use in telecommunication systems. It was designed for use in distributed and fail-safe soft real-time systems. The Erlang ecosystem includes a standard library of modules and a library of template solutions, known as the Open Telecom Platform framework.

Programs written in Erlang are compiled into bytecode, executed by a BEAM virtual machine, whereby there can be several virtual machines on different nodes of a distributed computing network. Erlang development software supports hot patching, which prevents the system from stopping when updates are installed.

In recent years, Erlang is used not just in telecommunication systems. Many companies use a dedicated Erlang developer to createf high-load distributed web apps. For example, Facebook chat and WhatsApp are written in Erlang. Erlang also is used in several NoSQL databases of high accessibility. Plus, the Erlang virtual machine is used in the Elixir programming language. The Elixir programming language itself is based on Erlang, which provides distributed, fail-safe, soft real-time execution, metaprogramming with macros and polymorphism. Basically, Elixir is an add-on to Erlang, simplifying development and preserving all the advantages of Erlang.
