How does Scala support adaptive backpressure-aware load balancing?

Adaptive load balancing routes traffic based on system load and backpressure signals.

In Scala-based reactive systems, load balancing can be enhanced by incorporating runtime metrics such as queue depth, CPU usage, and backpressure signals. Instead of static round-robin, traffic is routed dynamically to healthier nodes. Akka Cluster tools and service mesh integrations help achieve adaptive routing. This ensures system stability under uneven load distribution.
