What scaling methods, besides using worker threads, are you familiar with?

In addition to using worker threads in Node.js, there are other scaling methods:

• Clustering (Cluster module) — allows running multiple Node.js processes that can utilize all CPU cores, distributing the load.

• Load Balancing — using external load balancers (e.g., Nginx) to distribute requests among multiple application instances.

• Microservices architecture — splitting the application into independent services that can be scaled separately.

• Using message queues (RabbitMQ, Kafka) — for asynchronous task processing and offloading the main thread.

• Caching (Redis, Memcached) — reduces database load and speeds up response times.

Each of these methods helps improve the performance and resilience of the application.
