Discord: 5,000,000 Concurrent Users and Millions of Events per Second

Discord embraced Elixir early, leveraging the Erlang VM for a highly concurrent, real-time system. The Elixir prototype established today's infrastructure. We'd choose the same path again!

Elixir is Special

Elixir is a functional programming language built on the BEAM, a foundation that's almost 40 years old.

BEAM is a one-of-a-kind runtime that utilizes parallelism and fault tolerance.

Elixir applications behave predictably when things go wrong.
Elixir applications can fully utilize all CPU cores without having to write complex code.
No other language on the planet can achieve the same level of parallelism with the ease of writing the code.
Elixir also allows you to write serial code.

Simply put, Elixir has an unparalleled capability to manage high levels of concurrency and handle faults while allowing clean code writing.

Elixir Case Studies

Real-world examples of how Elixir, Erlang, BEAM, OTP, Phoenix tech stack has been successfully implemented, and the key benefits and results achieved.

Bleacher Report

150 servers were reduced to just 8
Ability to handle 8x the traffic without autoscaling
Adding content to all streams went from 30-40 seconds to 3-4 seconds
95th percentile latency hovers around 100ms and is not noticeably affected by traffic spikes
Runs on about 1/10th of the servers with low CPU utilization
10x reduction in the time it takes to update the site
The system easily handles over 200 million push notifications per day

Only 50 Software Engineers and 900,000,000 Users
Back in 2011, WhatsApp was able to handle one million established TCP sessions on a single machine, with plenty of memory and CPU capacity to spare.
Back in 2013, WhatsApp managed to process a whopping 18 billion messages within just 24 hours. This included 7 billion incoming messages and 11 billion outgoing messages.
