License](https://github.com/CloudI/CloudI/blob/master/src/LICENSE)\n\n## ABOUT\n\n### What is CloudI?\n\n(short answer) \"A distributed application server that provides efficient\nmessaging for many programming languages within a single service abstraction\nthat is both scalable and fault-tolerant.\"\n\n(shorter answer) \"A rock-solid transaction processing system for flexible\nsoftware development.\"\n\n(shortest answer) \"A Cloud at the lowest level.\"\n\n### Who would use CloudI?\n\nSoftware developers that do not want to get locked into corporate vendors\nor frameworks that push for perpetual commercial support or licenses.\n\n### Why should CloudI be used?\n\nCloudI makes software fault-tolerant and scalable, utilizing Erlang,\neven if the software is legacy source code.  CloudI mitigates\nsoftware development risk (delays or failures) when making\nsoftware scale in non-Erlang programming languages, or during a conversion\nof a software system (fully or partially) to the Erlang programming language.\n\n### How should CloudI be used?\n\nThe CloudI API provides a simple set of functions for\nService-Oriented Architecture (SOA) development in any supported language\n(currently ATS, C/C++, Erlang/Elixir, Go, Haskell, Java, JavaScript,\n OCaml, Perl, PHP, Python, Ruby and Rust):\n\n* `subscribe`, `unsubscribe`, `subscribe_count`\n* `send_async`, `send_sync`, `mcast_async` (`mcast_async` == publish)\n* `recv_async`\n* `return`, `forward`\n\nExternal communication that needs to scale (beyond 10,000 connections)\ncan use an existing internal CloudI service (implemented in Erlang or Elixir)\nwhich may do processing for one or more external CloudI services\n(implemented in ATS, C/C++, Go, Haskell, Java, JavaScript, OCaml, Perl, PHP,\n Python, Ruby and/or Rust)\n\nEven if external communication doesn't need to scale, private cloud\ncomputing tasks (number crunching) can gain fault-tolerance and internal\nsystem scalability within CloudI.\n\n### Where should I find more information?\n\nPlease see the [FAQ](https://cloudi.org/faq.html) for more details.\n\n## INSTALLATION\n\n### Requirements\n\n* `Erlang \u003e= 22.0` (`erlang
