11.1 What is a load balancer?

A load balancer allows you to distribute the workload (for example of the Web Server, Email Server, Database Server ...) balancing it between two or more Cloud Servers. To load balance the workload the Cloud Servers need to have an identical configuration and contain the same data.

By using a load balancer that is connected to a set of Cloud Servers, via redundancy, increases the level of reliability and guarantees the continuity of the provided service. This allows you to optimize the resources of your structure, maximizing productivity and reducing the response times, therefore avoiding possible overloads.
Should one of the Cloud Servers that are being balanced stop working for any reason, the load balancer will automatically exclude it from the balance and use the other Cloud Servers, therefore guaranteeing the  continuity of the provided service; at the same time the system will send an Email and/or SMS notification to the contact details entered when activating the service or after the activation.

The load balancer is recommended in all cases whether you require one or more of the following:
  • guarantee continuity of the provided service
  • be ready for sudden peak traffic
  • manage high traffic levels

Service costs

The service has a monthly cost (30 days) which is deducted in advance from the credit upon activation (for more information see the price list). The cost is not affected by the number of and type of rules that are used, by the number of balanced Cloud Servers/Dedicated Servers and by the status of the load balancer. If a load balancer is deleted the cost charged in advance will be lost.
