Best Load Balancing Software

Load balancing software helps distribute resources and incoming traffic to websites or applications. High-traffic sites require distribution tools to effectively scale infrastructure support and ensure proper functionality. These tools help network administrators and IT managers control and distribute traffic across servers, server farms, or server pools. Some solutions provide automation via balancing algorithms that identify fluctuations and distribute resources efficiently. Without load balancing software, companies with high-volume traffic and those with rapidly fluctuating traffic flows would waste resources and potentially damage server equipment. Inefficient resource usage could cause poor functionality, and damaged infrastructure hardware could cause complete site or application failure.

To qualify for inclusion in the Load Balancing category, a product must:

  • Monitor web traffic and distribute resources
  • Scale infrastructure workloads to match traffic
  • Provide or integrate with failover and backup services
