🔗 Scaling real-time apps: Elixir libcluster PubSub vs Node.js

When building distributed, real-time applications, choosing the right tools for communication and scaling is crucial. Elixir, with its powerful concurrency model and libraries like libcluster and Phoenix PubSub, excels at handling thousands of concurrent connections and distributed messaging. In contrast, Node.js, while capable, faces challenges in scaling real-time features across multiple nodes.

Today we dive into how Elixir’s libcluster and PubSub work, how they compare to Node.js solutions, and why Elixir is a better choice for large-scale, distributed real-time apps.
