Select your load balancing approach based on requirements:
Traffic volume: Low traffic can use a single NGINX. High traffic might need dedicated hardware or cloud-managed balancers.
Routing complexity: Simple round-robin works for homogeneous backends. Content-based routing needs Layer .
Budget: Open-source HAProxy costs nothing but requires expertise. Cloud balancers cost money but reduce operational burden.
Environment: On-premises might use F hardware. Cloud-native apps use provider-managed balancers. Kubernetes uses Ingress controllers.
