I am a self-taught engineer, so I did not get pulled into Matlab in college. The company purchased team licenses for the Pragmatic Studio’s Elixir courses, which were invaluable. Not sure why bytecode generated by a APLv2 project Erlang Developer job couldn’t be executed in a fully open source environment.
Significance in modern software development
The main reason is the constant emergence of new programming languages. However, some programming languages, such as Erglang, have been challenging for years. If you are also thinking of learning a programming language, don’t worry, because you don’t need any previous programming experience.

It makes the code easier to understand and maintain, reduces maintenance costs and stops developers from reinventing a square wheel. Erlang is a distributed, fault-tolerant functional programming language well-suited for building massively scalable soft real-time systems. Originally developed by Ericsson in 1986 for telecom applications, Erlang has since spread to companies like WhatsApp, Klarna, and Discord who rely on its capabilities for high availability and uptime. Erlang is a prominent programming language and an excellent runtime environment. It’s an asynchronous language that completes tasks quickly and has built-in functions for distribution and fault tolerance. It’s a robust and dynamically typed language with high scalability.
What is Erlang?
- They write the code, the unit tests, the integration tests, deployment, health/readiness checks, and if all that passes then the deployment tools take care of swapping in the new process with zero downtime.
- The language was initially designed to address the demanding requirements of telecommunication infrastructure, showcasing its robustness in managing numerous concurrent processes and ensuring fault tolerance.
- One of the first things I try to find out when I meet a programming language inventor is what problem were they trying to solve when creating the language.
- Erlang can easily provide that since it has inherent fault tolerance and increasing uptime of the system.
- Used Erlang to run messaging servers, achieving up to 2 million connected users per server.
- Any long-distance calls you made in the UK were routed using Erlang through an AXD301 switch.
The main purpose of developing Erlang was to use it in telecommunication services. That’s why it includes a sophisticated runtime environment and OTP libraries. The applications and systems developed using Erlang and OTP are more adaptable and result-oriented. Java, Eiffel and some other languages have type systems which are mostly checked at compile time, but with some remaining checking done at run time. Such type systems provide some guarantees about types which can be exploited by the compiler, this can be useful for optimisation. During the 1980s there was a project at the Ericsson Computer Science Laboratory which aimed to find out what aspects of computer languages made it easier to program telecommunications systems.

Very technologically cool, but I’d much rather inject the new functionality into the source code. From there it can it make its way through the unit tests, integration tests, deployment, health/readiness checks, and if all that passes then I’ll allow it to be called. I would think (without knowing too much about Erlang’s mechanisms) that the mechanisms of Erlang are quite different from what a Lisp runtime typically does.
- For example, you study constantly for a certain period of time, and then play by finding a way to apply everything you have learned so far.
- Else I think we will see Erlang in a few companies, and it will be more of a building block for Elixir.
- The most common class of ‘less suitable’ problems is characterised by performance being a prime requirement and constant-factors having a large effect on performance.
- To implement this, code is loaded and managed as “module” units; the module is a compilation unit.
- They are neither operating system processes nor threads, but lightweight processes that are scheduled by BEAM.
- Due to its concurrency distribution properties, engineers can use Erlang to develop instant messaging applications.
Why did WhatsApp choose Erlang?
It is process-oriented, ie more isolated processes that communicate with each other via messages. The result of this operation is the creation of new messages, changes in the state of messages and similar actions. The system is very flexible when it comes to adding more machines to the network. Pure functions, higher order functions, and pattern matching are often used. That’s why we say that this language is used to create a system that manages a third-party gateway. For example, millions of messages are exchanged daily between different users.
