Scalability, Reliability and Security for E-Business in the INTERSTAGE
Application Server

Abstract
--------

Despite the  significant challenges posed  by the introduction  of new
e-commerce initiatives,  the promise  of customer and  revenue growth,
together with productivity improvements and cost savings, continues to
drive the implementation of  e-business systems. One key ingredient is
the  middleware   infrastructure  used  to   support  the  application
environment.

INTERSTAGE  Application Server  is an  advanced  application execution
platform  that  uses the  latest  Internet  software technologies  and
standards, like  J2EE, CORBA and  SOAP. To ensure a  non-stop service,
INTERSTAGE  Application  Server  integrates  OLTP functions  built  by
Fujitsu,  based  on  its  long history  of  building  mission-critical
systems.  It incorporates advanced  technologies, such  as hot-standby
and  dynamic application  swapping, in  order to  create  systems that
operate at extremely high levels of reliability and availability.

This  presentation  aims  to   show  possible  architectures  of  such
environments,  explaining  how INTERSTAGE  is  able  to provide  these
requirements  when running  entreprise applications,  both in  J2EE or
CORBA architectures. Topologies  of distributed objects, multi-server,
non-centralized administration, distributed transactions will be shown
and discussed.
