Learn More About Load Balancing Software

What is Load Balancing Software?

Load Balancing software is used to organize resources to applications or websites as traffic demands. Business use Load Balancing tools to automate resource distribution so that they do not have to pay for more resources than they need, and can ensure that their applications and websites can handle sudden spikes in traffic. Businesses that don’t use load balancing tools may distribute resources efficiently, which can result in increased costs, or in the worst-case scenario, application, or website failure under heavy traffic. Load balancing tools are essential for businesses with multiple applications and websites or applications that highly vary in the amount of traffic they have at any given time.

Features & Capabilities

The most common features of load balancing tools are as follows:

  • Resource Distribution
  • Traffic Monitoring

Many vendors offer discounts for businesses that handle large amounts of queries in a month.
