Erlang vs Tornado: What are the differences?

What is 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.

What is Tornado? A Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

Erlang can be classified as a tool in the "Languages" category, while Tornado is grouped under "Frameworks (Full Stack)".

"Real time, distributed applications" is the primary reason why developers consider Erlang over the competitors, whereas "Open source" was stated as the key factor in picking Tornado.

Erlang and Tornado are both open source tools. Tornado with 17.9K GitHub stars and 4.97K forks on GitHub appears to be more popular than Erlang with 7.7K GitHub stars and 2.09K GitHub forks.

According to the StackShare community, Erlang has a broader approval, being mentioned in 70 company stacks & 45 developers stacks; compared to Tornado, which is listed in 69 company stacks and 16 developer stacks.

    What are some alternatives to Erlang and Tornado?
    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,

    SpreadServe's RealTimeWebServer is built in Tornado. Spreadsheets loaded into SpreadServeEngine instances are projected into browsers using Tornado. Server side recalcs are pushed to the browser using web sockets.

    setup an api for a client with tornado backend. incredibly fast and lightweight. unfortunately breaks down when using third party libraries which block internally.

    Tornado with Async/Await coroutines provided in Python 3.5 make up for an excellent stack for a micro-service.
