Elixir is a new generation functional & concurrent programming language built on top of Erlang's VM - BEAM. It's a language designed for productivity, extensibility & maintainability, brining in best of Erlang's fault-tolerance, distributed computing & concurrency.
Phoenix is the most popular web framework for Elixir language that makes building Real Time applications, APIs and web applications super easy. Phoenix is fast and has excellent support for handling large numbers of concurrent users with very low latency and response times.
As a compiled, dynamically typed language with a functional paradigm, Elixir allows engineers to rapidly build and prototype ideas, reduce unnecessarily shared state (a common source of bugs). The compiling of Elixir to Erlang byte code allows an Elixir application to be extremely performant while also being highly fault tolerant. The language’s focus on simplicity of syntax simplifies the task of client engineers ramping up and maintaining projects.
The Phoenix framework, as its name suggests, rose from the experience of earlier rapid web development frameworks such as Ruby on Rails, took their lessons and applied them using the strengths of the Elixir language and ecosystem. Phoenix serves several versatile needs which frequently come up on server-side development:
Phoenix is an excellent choice for classical web application development. It has all the bells and whistles one would expect for a project in this class and our engineers have used it to great effect with our clients.
In today’s world, applications often package and present information to a variety of clients in a variety of formats from a variety of sources. Phoenix has robust libraries for building those API whether they be traditional REST or GraphQL (or both). Our team has extensive experience building and consuming APIs and Phoenix provides a great model to build robust API servers.
A pioneering approach to web development, LiveView allows information about your application clients to be kept server side, but thanks to Elixir’s facility with concurrency, allows for rich interactions on the client side for the cases where a product requires a robust interaction pattern, but does not meet the bar for a full fledged client side single page application.
Elixir applications can respond in microseconds. You can handle more requests on the same hardware.
E.g. E-commerce, Social Media, APIs
Perfect for fault-tolerant & decentralized system - load is spread across multiple connected systems.
E.g. Metrics based Dashboard, Business Intelligence
Server side push notifications across different clients web or mobile on a Real Time basis.
E.g. Chat Application, Messaging Platform, Dashboards
Rely on being available 24/7 (100% up-time) with proven fault tolerant & fail safe Erlang's OTP engineering
E.g. Payment Systems, Video Streaming, SaaS Applications
Integrations with external services, have to wait and respond to asynchronous events.
E.g. Gamification, Send email or notification based on an event, Chat Bots
With built-in Micro-services & fault tolerance architecture of OTP & Functional language paradigm, Elixir is very much suited for Large Enterprise Applications
E.g. ERP, CRM, Workflow Applications
