Virtual Business Services provide continuous high availability and reduce frequency and duration of service disruptions for multi-tier business applications running on heterogeneous operating systems and virtualization technologies. A Virtual Business Service represents the multi-tier application as a single consolidated entity and builds on the high availability and disaster recovery provided for the individual tiers by Symantec products such as Symantec Cluster Server and Symantec ApplicationHA. Additionally, a Virtual Business Service can also represent all the assets used by the service such as arrays, hosts, and file systems, though they are not migrated between server tiers. A Virtual Business Service provides a single consolidated entity that represents a multi-tier business service in its entirety. Application components that are managed by Symantec Cluster Server or Symantec ApplicationHA can be actively managed through a Virtual Business Service.

You can configure and manage Virtual Business Services created in Veritas Operations Manager by using Veritas Operations Manager Virtual Business Services Availability Add-on. Besides providing all the functionality that was earlier available through Business Entity Operations Add-on, VBS Availability Add-on provides the additional ability to configure fault dependencies between the components of the multi-tier application.
