== Erlang/OTP == [[File:Erlang OTP logo.svg|thumb|right|150px|Erlang/OTP logo]] Erlang/OTP ([[Open Telecom Platform]]) is a suite of libraries, modules, and tools for building massively scalable, fault-tolerant, and distributed systems. It provides a solid foundation for the development of concurrent Erlang applications by offering a set of ready-to-use components and abstractions. === Overview === Erlang/OTP is built on top of the Erlang programming language, developed by Ericsson. It introduces a set of design principles and practices aimed at simplifying the development of reliable and efficient systems. The core ideas behind Erlang/OTP are: * [[Actor Model]]: Concurrency is managed through lightweight, isolated processes called actors, which communicate by exchanging messages. * [[Supervision Tree]]: Fault tolerance is achieved using a hierarchical structure of supervised processes. Failures in child processes can be automatically handled and recovered from. * [[Hot Code Loading]]: Erlang/OTP supports upgrading running systems without any downtime. New versions of code can be loaded dynamically, ensuring smooth and continuous operation. * [[OTP Behaviors]]: Behaviors are generic programming interfaces that provide common functionalities and conventions for building fault-tolerant systems. Examples of OTP behaviors include supervisors, gen_servers, and gen_fsm. === Key Components === Erlang/OTP is composed of several key components. Some of the most important ones are: * **OTP Modules**: A wide range of modules for managing processes, message passing, error handling, and more. * **Erlang/OTP Libraries**: A collection of libraries providing utilities for tasks such as networking, database access, parsing, and memory management. * **OTP Behaviors**: A set of behavior modules that define callback functions and conventions for building generic components like supervisors, gen_servers, state machines, and event handlers. * **Application Framework**: The OTP application framework allows developers to structure their systems into self-contained applications, each with its own supervision tree. * **Release Handling**: Erlang/OTP includes tools for packaging applications into releases. A release is a self-contained bundle including code, configuration, and runtime environment. === Use Cases === Erlang/OTP has been used to build a wide range of systems, from telecommunication networks and financial trading platforms to multiplayer online games and social media applications. Its fault-tolerant design and ability to handle massive concurrency make it well-suited for creating reliable and scalable distributed applications. == See Also == * [[Erlang (programming language)]] * [[Concurrency (computer science)]] * [[Fault Tolerance]] * [[Supervisor (computer science)]] * [[Gen Server]] * [[Gen FSM]] == References == {{reflist}} [[Category:Elixir (programming language)]] [[Category:Concurrent computing]] [[Category:Distributed computing]] [[Category:Fault tolerance]]
