Choose the Best
Platform for Your ASP
ASPs take advantage of
existing Internet
connectivity to offer
corporations the
opportunity to outsource
not only peripheral
applications but also
mission-critical
applications. This trend
will continue to escalate
as customers discover that
outsourcing firms can
deliver mission-critical
applications that meet
their demands for service
licensing agreements
(SLAs). For ISPs and ASPs,
these application-hosting
responsibilities require the
choice of a platform that
can deliver the correct
balance of performance,
scalability, upgradeability
and manageability.
