Load Balancing

Load Balancing is a way to distribute workloads across multiple computing resources. Load Balancing is typically used to improve the reliability of a service through redundancy.

Features and Benefits

A virtual IP address [VIP] can be created on a load balancing cluster. The VIP can be configured to forward traffic received on specified ports to other IP/Port combinations. Customers will need to specify the traffic to be load balanced, and where traffic should be sent. 

When a VIP is created, and the destination services are identified, the load balancer will begin to monitor those destination services for their availability. 

If a destination service is unavailable, the load balancer will stop sending traffic to it until the service recovers.


This is a 24x7 service supported by the Network Operations Center (NOC). Escalation is provided through Data Center Operations and the NOC on-call rotation.

For planned maintenance, the NOC follows the ITS Change Management Process, and planned changes are posted on the ITS Maintenance Calendar.

Data Security

This service is appropriate for confidential and most types of restricted data (as defined here).


This service is available to all UCSC academic and administrative departments who are hosting in the UCSC Data Center.


For FY2014-15, the rate for load balancing is $265/year per configuration item. Each VIP, and each server/service pair, are configuration items.
