Load balancing, simply, is the distribution of a workload across many nodes. In the webhosting industry, it is typically used for balancing http traffic over multiple servers acting together as a web front-end.
Load Balancers allows users to intelligently distribute traffic to a single IP across any number of Storm Servers. This means that traffic can be shared across multiple servers to increase performance during times of high activity, increasing the reliability of your web application. You can scale up in anticipation of a traffic increase, and back as your traffic slows, paying for only what you need. Load Balancing also allows you to build your application with redundancy in mind. If one of your server nodes fails, the traffic is distributed to your other nodes without any interruption of service.
Load Balancing is fault tolerant and redundant by utilizing multiple servers running Zeus Load Balancer 7.
When and Why to Use Load Balancing
Load balancing, by its very nature, is the solution for more than one problem. You can use load balancing to keep your site up through traffic spikes, or grow with you as your resource needs increase.
The most common uses for Load Balancing:
-
Failover and Redundancy: If one node fails, the traffic is redistributed and your site stays up.
-
Load Distribution: As your site gains popularity, share the load across many nodes.
-
Preparation for Traffic Spikes: If you are anticipating an increase in traffic you can clone your server, and load balance between them before the traffic hits.
