After attending Oracle Openworld in October I've been thinking about performance issues with Oracle applications over the wide area network (WAN). With the changing business environment IT organizations are re-architecting how they deploy enterprise applications. Oracle applications automate business processes and increase productivity, but in this new network-centric world their performance is being impacted by longer WAN links and inefficient Internet protocols resulting in reduced performance and decreased user productivity.
Globalization and outsourcing has created a workforce that is spread across the world. At the same time, to reduce IT costs resulting from the spread of regional systems, and to take advantage of large scale virtualized systems, organizations are centralizing their application and IT infrastructure in the data center. The result of this trend is that the distance from the end user to the application server has increased dramatically and the connection is often over links with limited bandwidth.
