Okanye ngaba kunokwenzeka? Ngokuqinisekileyo, ukufuduka kweenkqubo ze-SAP kuyinkqubo enzima kwaye ibuhlungu, ukuphumelela kwayo kufuna umsebenzi olungelelanisiweyo wabo bonke abathathi-nxaxheba. Kwaye ukuba ukufuduka kwenziwa ngexesha elifutshane, umsebenzi uba nzima kakhulu. Asinguye wonke umntu ogqiba ukwenza oku. Kusenokubakho izizathu ezininzi. Umzekelo, inkqubo ngokwayo inde kwaye intsonkothile kumbutho. Kwaye kukho umngcipheko wokungacwangciswanga kwexesha lokuphumla kwenkqubo. Okanye abaxumi abaqinisekanga ukuba, emva kokuba benziwe olo tyando, baya kufumana izibonelelo ezilingana nemigudu esele yenziwe. Noko ke, kukho iimeko ezikhethekileyo.
Ngezantsi kwe-cut, siza kuthetha malunga nobunzima abajongene nabathengi kwinkqubo yokufuduka kunye nokugcinwa kweenkqubo ze-SAP, sixoxe ukuba kutheni i-stereotypes ayisoloko ihambelana nenyani, kwaye sabelane ngesifundo somzekelo wendlela esikwazi ngayo ukufuduka kwiinkqubo zomthengi amaziko amatsha kwisithuba nje seenyanga ezintathu.
Iinkqubo ze-SAP zokubamba
Kwiminyaka emihlanu edlulileyo, kwakunzima ukucinga ukuba abathengi baqala ukusebenzisa izixhobo zokubamba izicelo ze-SAP. Kwiimeko ezininzi ziye zaphunyezwa kwindawo yokuqala. Nangona kunjalo, ngokuphuhliswa kweemodeli zokukhupha kunye nemarike yeenkonzo zefu, umbono wehlabathi wabathengi waqala ukutshintsha. Ziziphi iingxoxo eziphembelela ukhetho oluxhasa ilifu le-SAP?
- Kwabaqalayo abasandul 'ukucwangcisa ukuphumeza i-SAP, iziseko zefu ziphantse zikhethwa ngokusemgangathweni - ukulinganiswa kwezixhobo kwiimfuno zangoku zenkqubo kunye nokungafuni ukuguqula izixhobo ekuphuhliseni ubuchule obungekho ngundoqo.
- Kwiinkampani ezinomhlaba wenkqubo enkulu, ngoncedo lokusingatha iinkqubo ze-SAP, ii-CIO zifikelela kwinqanaba elahlukileyo lolawulo lomngcipheko, kuba Iqabane linoxanduva lwe-SLA.
- Ingxoxo yesithathu eqhelekileyo yindleko ephezulu yokwakha iziseko zophuhliso ukuphumeza ukufumaneka okuphezulu kunye neemeko zeDR.
- I-Factor 2027 - umthengisi ubhengeze ukuphela kwenkxaso yeenkqubo zelifa ngo-2027. Oku kuthetha ukukhutshelwa kweziko ledatha kwi-HANA, nto leyo ebandakanya iindleko zokuphucula nokuthengwa kwamandla amatsha ekhompyutha.
Imakethi yokubamba i-SAP eRussia ngoku ingathathwa njengeqolileyo. Kwaye oku kunika ithuba elaneleyo kubathengi abafuna ukutshintsha iiplatifti zabo zokubamba. Nangona kunjalo, iiprojekthi ezinjalo zinokubangela inkxalabo phakathi kwamashishini ngenxa yobunzima benkqubo yokufuduka. Oku kunyanzela abathengi ukuba babeke iimfuno ezongeziweyo kubaboneleli benkonzo, abamele babe nobuchule obukhethekileyo kuphela ekubambeni nasekugcineni iinkqubo ze-SAP, kodwa kunye namava aphumeleleyo kwintsimi yokufuduka.
Ziziphi iingxaki zokutshintsha ukusingathwa kwe-SAP?
Ukwamkela iindwendwe kwahlukile. Ukungahambelani nenqanaba lenkonzo ebhengeziweyo, ezininzi "i-buts" kunye ne-asterisks kunye nokugcinwa kwisicatshulwa esincinci, izixhobo ezincinci kunye nobuchule bomnikezeli wokubamba, ukungabikho kokuguquguquka kwimiba yokunxibelelana nomxhasi, i-bureaucracy, imida yobugcisa, ubuchule obuphantsi benkxaso yobugcisa. iingcaphephe, kunye nezinye izinto ezininzi - ezi yinxalenye nje encinane imigibe ukuba abathengi banokudibana xa beqhuba iinkqubo zabo zoshishino kumaziko angaphandle. Ngokuqhelekileyo, kumthengi, konke oku kuhlala emthunzini, kwihlathi lenkontileka yamaphepha amaninzi, kwaye kuvela kwinkqubo yokusebenzisa iinkonzo.
Ngexesha elithile, kuyacaca kumthengi ukuba inqanaba lenkonzo alifumanayo likude nokulindela kwakhe. Olu luhlobo lwe-catalyst yokufumana izisombululo zokulungisa imeko kwaye, kwimeko yokungaphumeleli, xa iingxaki ziqokelela kumda kwaye ziba buhlungu kakhulu, ziqhubela phambili kwizenzo ezisebenzayo ukuphuhlisa ezinye iindlela zokhetho kwicala lokutshintsha umnikezeli wenkonzo. .
Kutheni belinda de kube ngumzuzu wokugqibela? Isizathu silula - inkqubo yokufuduka kweenkqubo kubathengi ayisoloko ibonakala kwaye iyaqondakala. Kunzima kumxhasi ukuvavanya imingcipheko yokwenene ehambelana nenkqubo yokufuduka. Sinokuthi ukufuduka kubathengi luhlobo lwebhokisi elimnyama: akucaci, ixabiso, ixesha lokunciphisa inkqubo, iingozi kunye nendlela yokunciphisa, kwaye ngokubanzi kumnyama kwaye kuyoyikisa. Kufana, ukuba ayisebenzi, ke iintloko ziya kuqengqeleka zombini phezulu kunye nabadlali.
I-SAP yinkqubo yenqanaba loshishino, entsonkothileyo kwaye, ukuyibeka kancinci, ayitshiphuki. Uhlahlo lwabiwo-mali olufanelekileyo luchithwa ekuphunyezweni, uhlengahlengiso, kunye nokugcinwa kwalo, kwaye ubomi beshishini buxhomekeke kubukho balo kunye nokusebenza okuchanekileyo. Ngoku khawucinge ngemiphumo yokumisa imveliso ethile enkulu. Ezi zilahleko zemali, ezinokuthi zibalwe ngamanani kunye nenani elikhulu le-zero, kunye nodumo kunye neminye imingcipheko ebalulekileyo ngokulinganayo.
Siza kuhlalutya ubunzima obunokuthi buvele kwinqanaba ngalinye kwimeko yokufuduka kweenkqubo ze-SAP ukusuka komnye wabathengi bethu.
Ukulungiselela kunye noyilo
Ukufuduka kuyifomula enamalungu amaninzi awohlukeneyo. Kwaye enye yeyona nto ibaluleke kakhulu yinqanaba lokuyila kunye nokulungiselela isiseko esijoliswe kuyo (esitsha).
Kwakufuneka singene ekuphunyezweni okukhoyo kweenkqubo, ulwakhiwo lwazo. Kwiziseko ezingundoqo ekujoliswe kuzo, siphindaphinda izisombululo ezikhoyo kwenye indawo, sizincedise kwaye siziphucule kwiindawo ezithile, siziphindaphinda kwenye indawo, sicinge nzulu kwaye sikhethe izisombululo zokuqinisekisa ukunyamezelana nokufumaneka, kwaye sidibanise zonke izixhobo kangangoko kunokwenzeka.
Ngethuba lenkqubo yokuyila, ukuzivocavoca okuninzi okuhlukeneyo kwenziwa, ekugqibeleni kwenza ukuba kube lula ukulungiselela ngokusemandleni ukufuduka kwaye kuthathelwe ingqalelo zonke iintlobo ze-nuances kunye nemigibe (ngaphezulu kubo kamva).
Into esiye sagqiba ngayo yilwakhiwo lwelifu lwabucala olusekwe kwiziko lethu ledatha:
- iiseva zomzimba ezinikezelweyo ze-SAP HANA;
- Iqonga le-VMware le-virtualization yeeseva zesicelo kunye neenkonzo zeziseko ezingundoqo;

Inkqubo yokufuduka
Ngokubanzi, inkqubo yokufuduka iqulathe ezi zigaba zilandelayo:
- ukulungiswa kwawo onke amaxwebhu eprojekthi ayimfuneko;
- uthethathethwano nomnikezeli okhoyo ngoku - ukusombulula imiba yombutho;
- ukuthengwa, ukuhanjiswa nokufakwa kwezixhobo ezitsha zeprojekthi;
- uvavanyo lokufuduka kunye nokulungiswa kwenkqubo;
- ukudluliselwa kweenkqubo, ukulwa nokufuduka.
Ekupheleni kuka-Okthobha ka-2019, sasayina isivumelwano, emva koko sayila i-architecture, kwaye emva kokuvumelana nomthengi, sayalela izixhobo eziyimfuneko.
Into ekufuneka uyibeke ingqalelo kuqala lixesha lokuhanjiswa kwezixhobo. Ngokomyinge, ukuhanjiswa kwe-hardware eqinisekisiweyo ye-SAP NAHA ehlangabezana neemfuno zomenzi wesoftware kwiiplatifti ze-hardware kuthatha iiveki ze-10-12. Kwaye kuthathelwa ingqalelo ixesha lonyaka (ukuphunyezwa kweprojekthi kwawela kanye ngoNyaka omtsha), eli xesha linokunyuka ngenye inyanga. Ngako oko, kwakuyimfuneko ukukhawuleza inkqubo ngokusemandleni: sasebenza kunye nomthengisi-umnikezeli kwaye savumelana ngokuhanjiswa ngokukhawuleza ngenqwelomoya (endaweni yeendlela zomhlaba kunye nolwandle).
NgoNovemba noDisemba zachithwa kulungiselelwa ukufuduka nokufumana ezinye zezixhobo. Senze amalungiselelo kwibhentshi yovavanyo kwilifu lethu likawonke-wonke, apho sisebenze kuwo onke amanyathelo aphambili kwaye sabamba ubunzima kunye neengxaki ezinokubakho:
- ulungiselele isicwangciso esineenkcukacha zonxibelelwano phakathi kwamalungu eqela leprojekthi kunye namaxesha omzuzu ngomzuzu;
- yakha ibhentshi yovavanyo yesiseko sedatha kunye neeseva zesicelo malunga nendlela efanayo naleyo yeziseko ezijoliswe kuzo;
- kulungiswe amajelo onxibelelwano ayimfuneko kunye neenkonzo zeziseko ezingundoqo ukuvavanya ukusebenza kohlanganiso;
- sebenza iimeko zokuqhawula;
- Ilifu likwasinceda ukuba senze iitemplates zoomatshini eziqwalaselwe kwangaphambili, esithe ke sazithumela ngaphandle kwaye sazithumela kwindawo ekujoliswe kuyo.
Kungekudala ngaphambi kweeholide zoNyaka oMtsha, ibhetshi yokuqala yezixhobo yafika kuthi. Oku kwenze ukuba kube nokwenzeka ukuhambisa ezinye iinkqubo kwi-hardware yokwenyani. Ekubeni kwakungekho yonke into efikileyo, sidibanise izixhobo ezitshintshileyo, ukubonelela esikwaziyo ukuvumelana nomthengisi kunye nabasasazi. Sifumene iintsalela zeziseko ezingundoqo ekujoliswe kuzo kwinqanaba lokugqibela.
Ukuhlangabezana nomhla wokugqibela, iinjineli zethu kuye kwafuneka zincame iiholide zoNyaka oMtsha kwaye ziqalise umsebenzi wokulungiselela iziseko ekujoliswe kuzo nge-2 kaJanuwari, phakathi kweeholide. Ewe, oku kuyenzeka ngamanye amaxesha xa kusitsha kwaye kungekho ezinye iindlela. Okusemngciphekweni yayikukusebenza kweenkqubo apho ubomi beshishini buxhomekeke kuzo.
Ulungelelwaniso oluqhelekileyo lokufuduka lubukeka ngolu hlobo: okokuqala, ezona nkqubo zincinci zibalulekileyo (imbonakalo-mhlaba yophuhliso, imbonakalo-mhlaba yokuvavanya), emva koko iinkqubo ezivelisayo. Inqanaba lokugqibela lokufuduka lenzeka ekupheleni kukaJanuwari nasekuqaleni kukaFebruwari.
Inkqubo yokufuduka yayicwangcisiwe ukuya kutsho kumzuzu. Esi sisicwangciso esisikiweyo esinoluhlu lwayo yonke imisebenzi, ixesha lokugqiba kunye nabantu abanoxanduva. Onke amanyathelo sele esetyenzisiwe ekufudukeni kovavanyo, ngoko ke ekufudukeni okuphilayo kwakuyimfuneko nje ukulandela isicwangciso kunye nokulungelelanisa inkqubo.
Ukufuduka kwenziwa ngokucwangcisiweyo kwizigaba ezininzi. Kukho iinkqubo ezimbini kwinqanaba ngalinye.
Isiphumo seenyanga ezintathu ze-sprint yayiyinkqubo esebenza ngokupheleleyo kwiziko ledatha ye-CROC. Ngokubanzi, iziphumo ezincumisayo zafunyanwa ngokusebenza kweqela; igalelo kunye nokuzinikela kwabo bonke abathathi-nxaxheba kwinkqubo bekuphezulu.
Indima yomthengi kwiprojekthi
