ElixirConf 2023 - De Wet Blomerus - Building a globally distributed router

Elixir

Discover how to build a globally distributed router using Elixir's unique features, including its plug architecture and built-in concurrency, to improve latency, scalability, and user experience.

Key takeaways

When building a globally distributed router, consider the impact on latency and physically route requests to the closest region.
A reverse proxy can be used to route requests and add latency without users noticing.
The Elixir programming language is uniquely well-suited for building a globally distributed router due to its ability to hold onto connections and handle many requests with little resources.
Building a router for a globally distributed application requires careful consideration of the different types of requests that need to be routed, the regions involved, and the data involved.
Using Elixir’s plug architecture and the Strangler pattern can help simplify the development of a globally distributed router.
When building a router, start with a simple architecture and iterate and refine as needed.
A globally distributed router can be used to improve latency and reduce the load on servers.
When dealing with complex routing scenarios, it may be necessary to have multiple nodes for redundancy and to handle failures.
The plug architecture in Elixir is designed to be easy to use and allows for easy insertion and removal of code.
The Strangler pattern is a technique used in Elixir to gradually replace legacy code with new code.
When building a globally distributed router, it’s important to consider the consistency and availability of the data involved.
Using Elixir’s built-in concurrency features can help improve performance and scalability.
A globally distributed router can be used to improve the user experience by reducing latency and improving the speed of responses.
When building a router, consider the different types of requests that need to be routed and the regions involved.
Elixir’s concurrency model can help to improve the scalability of a globally distributed router.
