Phoenix Framework
Phoenix is a web development framework written in the Elixir programming language, built on top of the Erlang VM (BEAM). It follows the Model-View-Controller (MVC) pattern and is designed for building scalable, real-time applications with high performance and fault tolerance. Phoenix leverages Elixir's concurrency model and OTP (Open Telecom Platform) to handle massive numbers of simultaneous connections efficiently.
Developers should learn Phoenix when building high-traffic web applications, real-time features like chat or live updates, or systems requiring high availability and fault tolerance, such as financial platforms or IoT backends. It's ideal for scenarios where low latency and scalability are critical, as its underlying Erlang VM excels at handling concurrent processes with minimal resource overhead.
