'SaaS', kapena 'Software monga Service', limafotokoza pamene olemba amaleka 'kapena kubwereka pulogalamu ya intaneti mmalo mogula ndi kuziyika pa makompyuta awo . Ndizofanana ndi anthu omwe amagwiritsa ntchito Gmail kapena Yahoo makalata othandizira, kupatula kuti SaaS ikupita patsogolo. SaaS ndi maziko otsogolera makompyuta onse: malonda onse ndi antchito zikwi adzathamanga zipangizo zawo zamakompyuta monga malonda okhomedwa pa intaneti. Ntchito yonse yogwiritsira ntchito ndikupulumutsa kusungirako idzachitidwa pa intaneti, ndi ogwiritsa ntchito kugwiritsa ntchito zipangizo zawo ndi mafayilo pogwiritsa ntchito osakatuli.
SaaS, pokhala ndi PaaS (hardware Platform monga Service), imapanga zomwe timatcha Cloud Computing .
SaaS ndi PaaS amafotokoza momwe bizinesi ikugwiritsira ntchito pulogalamuyi kuti ipeze mapulogalamu awo. Ogwiritsira ntchito amatsegula mafayilo awo ndi mapulogalamu pokhapokha pa intaneti, pogwiritsa ntchito makasitomala awo ndi apasipoti. Kuyambiranso kwa machitidwe a mainframe a 1950 ndi 1960 koma ofanana ndi ma intaneti ndi ma intaneti.
SaaS / Cloud Example 1: M'malo mogulitsirako Microsoft Word kwa $ 300, mtambo wa computing chitsanzo ungathe "kubwereka" mawu processing software kwa inu kudzera pa internet mwina $ 5 pa mwezi. Simungatseke pulogalamu iliyonse yapadera, komanso simungatseke pamakina anu apamanja kuti mugwiritse ntchito mankhwalawa pa intaneti. Mukungogwiritsa ntchito makasitomala anu amakono kuti mutsegule pa makompyuta aliwonse ogwiritsidwa ntchito pa intaneti, ndipo mungathe kupeza malemba anu ogwiritsira ntchito mofanana momwe mungapezere Gmail yanu.
SaaS / Cloud Example 2: bizinesi yanu yaing'ono yamalonda sizingagwiritse ntchito ndalama zambiri pamalonda. M'malo mwake, eni ake am'banjamo "angabwereke" kupeza malo osungirako malonda a pa intaneti, ndipo ogulitsa magalimoto onse amatha kupeza malingalirowa kudzera pamakompyutala awo omwe amagwiritsidwa ntchito pa intaneti kapena m'manja.
SaaS / Cloud Chitsanzo 3: mumasankha kuyamba gulu lachipatala mumzinda mwanu, ndipo mukusowa zipangizo zamakono kwa ovomerezeka, olamulira zachuma, 4 ogulitsa, 2 oyang'anira umembala, ndi aphunzitsi atatu.
Koma simukufuna kupwetekedwa mutu kapena mtengo wolipilira nthawi yothandizana ndi ntchito yopanga komanso kuthandizira zipangizo zamakina. M'malo mwake, mumapatsa gulu lonse la masewera olimbitsa thupi kuti mulowetse mtambo wa intaneti ndi kubwereka maofesi awo pa intaneti , omwe adzasungidwe ndi kuthandizidwa kwinakwake ku Arizona. Simudzasowa antchito othandizira nthawi zonse; mufunikira kokha thandizo la mgwirizano kuti pakhale ma hardware.
Ubwino wa SaaS / Cloud Computing
Kupindula kwakukulu kwa mapulogalamu monga ntchito ndi ndalama zochepa kwa aliyense wogwira ntchito. Ogulitsa malonda samasowa kuti azigwiritsa ntchito maola masauzande akuthandiza ogwiritsa ntchito pa foni ... iwo amangosunga ndi kukonza kope limodzi lopangidwa pa intaneti. Mofananamo, ogwiritsa ntchito sayenera kutaya ndalama zambiri zogulira mawu, spreadsheet, kapena zinthu zina zomaliza. Ogwiritsa ntchito amatha kubweza ndalama zowonetsera ndalama kuti apeze kopi yaikulu yaikulu.
Downsides ya SaaS / Cloud Computing
Kuopsa kwa Mapulogalamu monga Service ndi cloud computing ndi kuti ogwiritsa ntchito ayenera kuika chikhulupiliro chokwanira kwa ogulitsa mapulogalamu a pa Intaneti kuti asasokoneze utumikiwo. Mwanjira ina, wogulitsira pulogalamuyo amachititsa makasitomala ake "kuwatenga" chifukwa zolembedwa zawo zonse ndi zokolola zili m'manja mwa wogulitsa. Chitetezo ndi chitetezo cha fayilo yachinsinsi zimakhala zofunikira kwambiri, popeza intaneti yaikulu tsopano ili gawo la malonda.
Pamene bizinesi ya antchito 600 imasintha kupita ku cloud computing, iwo ayenera kusankha awo ogulitsa mapulogalamu mosamala. Padzakhala kuchepetsedwa kwakukulu kwa kayendetsedwe ka kayendetsedwe ka ntchito kuti mugwiritse ntchito mapulogalamu a cloud computing. Koma padzakhala kuwonjezeka kwa ngozi za kusokonezeka kwa ntchito, kulumikizana, ndi chitetezo cha intaneti.
