Qhov txiaj ntsig tseem ceeb muab rau cov neeg siv SaaS yog tias nws tuaj yeem zam kev txhim kho thiab tswj software thiab tuaj yeem tso nws tus kheej los ntawm cov software nyuaj / hardware xav tau. Tus neeg zov me nyuam ntawm SaaS software, tseem hu ua hosted software lossis on-demand software, yuav saib xyuas kev ruaj ntseg, muaj thiab kev ua tau zoo ntawm software vim lawv khiav ntawm tus neeg zov me nyuam cov servers. Siv ib tug multitenant architecture, ib daim ntawv thov yog xa mus rau tsheej lab ntawm cov neeg siv los ntawm internet browsers. Cov neeg siv khoom tsis xav tau daim ntawv tso cai ua ntej, thaum cov chaw muab kev pabcuam txaus siab rau tus nqi qis dua vim tias lawv tuav ib daim ntawv thov xwb.

Tsis zoo li SaaS, DaaS tsis tsuas yog muab cov ntawv thov lossis software, tab sis kuj muab cov ntaub ntawv cuam tshuam los ntawm cov ntawv thov. Txhawm rau tso cai rau cov neeg siv kom muaj qee yam kev tswj hwm cov ntaub ntawv, feem ntau lub chaw datacenter muaj peev xwm sib koom / cais cov ntaub ntawv yog teeb tsa. DaaS's architecture yog ntau tus neeg siv khoom thiab cov neeg yuav khoom yuav qhov kev pabcuam los ntawm kev them tus nqi them txhua hli.
