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.
