Load balancing is the process of distributing network traffic across multiple servers to ensure no single server bears too much demand. Load balancers improve application availability, reliability, and performance. Cloud load balancers (AWS ALB/NLB, Azure Load Balancer, GCP Cloud Load Balancing) automatically scale and provide health checks that route traffic away from unhealthy instances. For UAE businesses, load balancing is essential for applications that need to handle traffic spikes — such as during Dubai Shopping Festival or Ramadan campaigns.
