What is the Erlang language suitable for?

Erlang language is ideal for developing highly reliable, high-concurrency distributed systems, especially for real-time applications and communication systems. Here are some use cases where Erlang language is suitable:

1. In the telecommunications field, Erlang was originally developed by the Swedish telecommunications company Ericsson, making it ideal for applications in the telecommunications industry such as telephone exchanges, call centers, and SMS transmission systems. Erlang’s concurrent processing capabilities and fault tolerance make it an ideal choice for handling large numbers of concurrent connections and high availability requirements.
2. Instant messaging applications: Erlang is widely used in instant messaging applications. For example, WhatsApp Messenger was developed using Erlang and excels in handling large numbers of concurrent user connections.
3. Real-time monitoring and control systems: Erlang’s lightweight process model and message passing mechanism make it very suitable for developing real-time monitoring and control systems, such as industrial automation systems, network monitoring systems, and smart device control systems.
4. Distributed Systems: Erlang is very suitable for developing and managing distributed systems. It provides native support for distributed computing, including transparent message passing between processes and easy scalability of distributed nodes.

In conclusion, Erlang is suitable for developing distributed applications that require high reliability and high concurrency, especially real-time applications and communication systems.
