-- Main.hyperic - 02 Apr 2007 Charles Lee, VP of Engineering at Hyperic, will explain how Hyperic engineers took PostgreSQL, an open source database, and scaled it to handle the load of Hyperic HQ, a Java-based Open Source systems management project. Charles will discuss PostgreSQL performance tuning, and the difference between EJB and Hibernate. Scaling Open Source components to meet the reliability and feature needs of customers is quite a challenge, regardless of which tools are used. In this case, the flexibility of Open Source software and the usability of Java result in a cross-platform best-of-breed enterprise product.
