SummaryEnterprise applications are often based on tight-
ly coupled, central ized architectures. This results in
per formance bottlenecks, s ingle points of fai lures,
and poor response to changing requirements. The
PADRES system provides a secure, scalable, and resi l-
ient infrastructure for loosely coupled applications,
and al lows f lexibi l ity in reacting to changing busi-
ness and technological requirements.
Scalable ESB for SOA and EDA
Decentralized management and orchestration
Decoupled, event-driven application integration
Secure, failure-resilient and load-balanced messaging
Distributed, in-network complex event processing
Agile business activity and infrastructure monitoring

Content-based Publish/Subscribe
A PADRES over lay network consists of brokers and
cl ients. Brokers use content-based message routing
to provide scalable and rel iable ESB infrastructure
ser vices. Cl ients are application components that
interact through the overlay using the publish/sub-
scr ibe paradigm.
