Architecting a vRealize Business Solution : Design Considerations : 4.1 Architectural Overview : 4.1.2 vRealize Business Server
   
4.1.2 vRealize Business Server
The vRealize Business server is based on a Tomcat Server instance, communicating through the Java Persistence API (JPA) and the Hibernate framework to a VMware vFabric® Postgres database over a JDBC connection.
The data collector populates the local vFabric Postgres database with infrastructure events and usage statistics from vCenter Server. The vRealize Business server then consumes the collected data from the vFabric Postgres database.
The vRealize Business server uses the Quartz job scheduler to schedule hourly, daily, and monthly collection jobs. Quartz jobs collect the following data:
Endpoint inventory
Utilization
Cost formula
Reference library updates
Costs are then calculated and updated based on this data.
