Erlang vs Netty: What are the differences?

Erlang: A programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems; Netty: Asynchronous event-driven network application framework. Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server.

Erlang belongs to "Languages" category of the tech stack, while Netty can be primarily classified under "Concurrency Frameworks".

"Real time, distributed applications" is the top reason why over 49 developers like Erlang, while over 2 developers mention "High Performance" as the leading cause for choosing Netty.

Erlang and Netty are both open source tools. Netty with 19.9K GitHub stars and 9.05K forks on GitHub appears to be more popular than Erlang with 7.75K GitHub stars and 2.1K GitHub forks.

WhatsApp, Heroku, and thoughtbot are some of the popular companies that use Erlang, whereas Netty is used by Outbrain, Appian, and Rapido. Erlang has a broader approval, being mentioned in 70 company stacks & 47 developers stacks; compared to Netty, which is listed in 11 company stacks and 14 developer stacks.

        What are some alternatives to Erlang and Netty?
        Elixir
        Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.
        Haskell
        Go
        Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
        Clojure
        Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system.
        OCaml
        It is an industrial strength programming language supporting functional, imperative and object-oriented styles. It is the technology of choice in companies where a single mistake can cost millions and speed matters,

        Consul

        Postmates built a tool called Bazaar that helps onboard new partners and handles several routine tasks, like nightly emails to merchants alerting them about items that are out of stock.

        Since they ran Bazaar across multiple instances, the team needed to avoid sending multiple emails to their partners by obtaining lock across multiple hosts. To solve their challenge, they created and open sourced ConsulMutEx, and an Elixir module for acquiring and releasing locks with Consul and other backends.

        It works with Consul鈥檚 KV store, as well as other backends, including ets, Erlang鈥檚 in-memory database.

        Another major decision was to adopt Elixir and Phoenix Framework - the DX (Developer eXperience) is pretty similar to what we know from RoR, but this tech is running on the top of rock-solid Erlang platform which is powering planet-scale telecom solutions for 20+ years. So we're getting pretty much the best from both worlds: minimum friction & smart conventions that eliminate the excessive boilerplate AND highly concurrent EVM (Erlang's Virtual Machine) that makes all the scalability problems vanish. The transition was very smooth - none of Ruby developers we had decided to leave because of Elixir. What is more, we kept recruiting Ruby developers w/o any requirement regarding Elixir proficiency & we still were able to educate them internally in almost no time. Obviously Elixir comes with some more tools in the stack: Credo , Hex , AppSignal (required to properly monitor BEAM apps).
