'SaaS', okanye 'Iprojekthi njengeNkonzo', ichaza xa abasebenzisi 'baqeshisa' okanye baboleka isofthiwe ekhompyutheni kunokuba bathengise kwaye bayifake kwiikhompyutha zabo . Kuye imeko efanayo nabantu basebenzisa i-Gmail okanye ye-mail iinkonzo zeeposi, ngaphandle kokuba i-SaaS ihamba phambili. I-SaaS ingumgaqo osisiseko emva kwekhompyuter yangaphakathi: onke amashishini kunye namawaka abasebenzi baya kuqhuba izixhobo zabo zeekhomputha njengeemveliso eziqeshwe kwi-intanethi. Yonke imisebenzi yokucwangcisa kunye nokugcinwa kwefayile kuya kwenziwa kwi-intanethi, kunye nabasebenzisi abafumana izixhobo zabo kunye neifayile esebenzisa isiphequluli sewebhu.
I-SaaS, xa idibene ne-PaaS (i-Platform ye-hardware njengeNkonzo), yenze into esiyibiza ngokuba yi- Cloud Computing .
I-SaaS nee-PaaS zichaza imodeli yoshishino yabasebenzisi abangena kwi-hub ephakathi ukufikelela kwiimveliso zabo zeekhompyutha. Abasebenzisi bavula iifayile kunye nesofthiwe kuphela ngexesha le-intanethi, basebenzisa kuphela i- browser yabo kunye neephasiwedi. Kubuyiselwa kwimizekelo ye-mainframe ye-1950 kunye neye-1960 kodwa ihambelana nezikhangeli zewebhu kunye ne-intanethi.
I-SaaS / Cloud Example 1: endaweni yokuthengisa ikopi ye-Microsoft Word nge $ 300, imodeli ye-computing yefayili "iya kuqeshisa" isofthiwe yokucwangcisa igama kuwe nge-intanethi mhlawumbi i-dollar ayi-5 ngenyanga. Awuyi kufaka nayiphina isofthiwe ekhethekileyo, kwaye ungayivalelwa kumatshini wakho wasekhaya ukusebenzisa le mveliso erenjiweyo. Usebenzisa nje isiphequluli sakho sewebhu ukuba ungene kuyo nayiphi na ikhompyutha eyenziwe ngekhompyutha, kwaye ungakwazi ukufikelela kumaxwebhu akho okucoca amagama ngendlela efanayo ukuba uya kufumana i-Gmail yakho.
I-SaaS / Cloud Example 2: ishishini lakho lokuthengisa imoto elincinci aliyi kuchitha amawaka eedola kwi-database yolwazi. Kunoko, abanikazi beenkampani babeza "baqeshisa" ukufikelela kwisiseko esithengiselwano sokuthengisa i-intanethi, kwaye bonke abathengisa imoto babeza kufumana olo lwazi ngeekhomputer zabo ezivunyelwe ngewebhu okanye i-handhelds.
I-SaaS / Cloud Isibonelo sesi-3: unquma ukuqala iqela lezempilo kwindawo yakubo, kwaye ufuna izixhobo zecomputer kumkeli wakho, umlawuli wezemali, abathengisi aba-4, abaququzeleli bobulungu aba-2 kunye nabaqeqeshi aba-3.
Kodwa awufuni ukuba intloko okanye iindleko zokuhlawula abasebenzi be-IT-time-time to build and support those tools. Kunoko, unikezela bonke abasebenzi beekliniki zezempilo ukuba bafike kwifu le-intanethi kwaye baqeshise i- software yabo ye-intanethi kwi-intanethi , eya kugcinwa kwaye ixhaswe kwindawo ethile e-Arizona. Awudingi naliphi na abasebenzi abasebenzisa i-IT rhoqo; uya kufuna kuphela inkxaso yenkxaso yesivumelwano ukuqinisekisa ukuba i-hardware yakho igcinwa.
Izinzuzo ze-SaaS / i-Cloud Computing
Inzuzo eyinqobo yeSoftware njengoko iNkonzo iyancitshiswa indleko kubo bonke abathintekayo. Abathengisi beSofthiwe akudingeki bachithe amawaka eeyure ezisekela abasebenzisi phezu kwefowuni ... bazokugcina kunye nokulungisa enye ikopi ephakathi komkhiqizo wekhompyutha. Ngakolunye uhlangothi, abasebenzisi abayi ku funeka baqokelele iindleko ezinkulu eziphambili zokuthenga i-word processing, spreadsheet, okanye ezinye iimveliso zomsebenzisi wokugqibela. Abasebenzisi baya kunoko bahlawule imali yokuqeshisa yokuqeshisa ukufikelela kwiikopi enkulu.
I-Downsides ye-SaaS / i-Cloud Computing
Umngcipheko weSofthiwe njengeNkonzo kunye nefu yekhompyutha yinto yokuba abasebenzisi kufuneka babeke inqanaba eliphezulu lokuthembela kubathengisi beprogram ye-intanethi ukuba abayi kuphazamisa inkonzo. Ngendlela, umthengisi wesofthiwe ubamba abathengi bayo "ukubamba umkhosi" kuba onke amaxwebhu abo kunye nomkhiqizo ngoku sezandleni zomthengisi. Ukhuseleko kunye nokukhuselwa kwefayile yobumfihlo kuyimfuneko ngakumbi, njengoko i-intanethi enkulu ngoku yinxalenye yentengiso yoshishino.
Xa ishishini labasebenzi abangama-600 litshintshela ifu yekhompyutha, kufuneka bakhethe i-software yomthengisi ngokucophelela. Kuya kubakho iindleko zokulawula ezincinci ukusetyenziswa kweefayili yekhompyutha. Kodwa kuya kubakho ukwanda kweengozi zokuphazamiseka kwenkonzo, ukuxhuma kunye nokukhuseleka kwe-intanethi.
