Isebe le-IT ye-VTB amaxesha amaninzi kwafuneka lijongane neemeko ezingxamisekileyo ekusebenzeni kweenkqubo, xa umthwalo kubo wanda ngokuphindaphindiweyo. Ke ngoko, bekukho imfuneko yokuphuhlisa nokuvavanya imodeli eya kuxela kwangaphambili umthwalo ophakamileyo kwiinkqubo ezibalulekileyo. Ukwenza oku, iingcali ze-IT zebhanki zibeka iliso, zihlalutye idatha kwaye zifunde ukuzenzekelayo izibikezelo. Siza kukuxelela kwinqaku elifutshane ukuba zeziphi izixhobo eziye zanceda ukuqikelela umthwalo kunye nokuba ngaba bancedise ukwandisa umsebenzi.
Iingxaki ngeenkonzo zomthwalo ophezulu zivela phantse kuwo onke amashishini, kodwa kwicandelo lezemali zibalulekile. Ngeyure ye-X, zonke iiyunithi zokulwa kufuneka zilungele, kwaye ngenxa yoko bekuyimfuneko ukwazi kwangaphambili ukuba kuya kwenzeka ntoni kwaye kwanokumisela usuku apho umthwalo uya kuxhuma kwaye zeziphi iinkqubo eziza kudibana nazo. Ukungaphumeleli kufuneka kujongwe kwaye kuthintelwe, ngoko ke imfuno yokuphumeza inkqubo yokuhlalutya kwangaphambili ayizange ixoxwe. Bekuyimfuneko ukuhlaziya iinkqubo ezisekelwe kwidatha yokubeka iliso.
Ukuhlaziya emadolweni akho
Iprojekthi yomvuzo yenye yezona zinto zinovakalelo xa usilela. Yeyona nto iqondakalayo kuqikelelo, ngoko sigqibe ekubeni siqale ngayo. Ngenxa yoxhulumaniso oluphezulu, ezinye ii-subsystems, kubandakanywa neenkonzo zebhanki ezikude (RBS), zinokufumana iingxaki ngexesha lomthwalo ophezulu. Ngokomzekelo, abathengi abavuyiswa yi-SMS malunga nokufunyanwa kwemali baqala ukuyisebenzisa ngenkuthalo. Umthwalo unokutsiba ngaphezu komyalelo wobukhulu.
Imodeli yokuqala yoqikelelo lwenziwe ngesandla. Sithathe ukulayisha kulo nyaka uphelileyo kwaye sibala ukuba zeziphi iintsuku ezona ziphezulu zilindeleke: umzekelo, i-1st, i-15 kunye ne-25, kunye neentsuku zokugqibela zenyanga. Lo mzekelo wawufuna iindleko ezibalulekileyo zomsebenzi kwaye awuzange unikeze uqikelelo oluchanekileyo. Nangona kunjalo, ichonge i-bottlenecks apho kwakuyimfuneko yokongeza i-hardware, kwaye yenza ukuba kube lula ukunyusa inkqubo yokudlulisa imali ngokuvumelana nabaxumi be-anchor: ukuze banganikeli imivuzo kwi-gulp enye, ukuthengiselana okuvela kwimimandla eyahlukeneyo kwahlukaniswa ngexesha. Ngoku sizicubungula kwiindawo apho iziseko ze-IT zebhanki zinokuthi "zihlafune" ngaphandle kokusilela.
Ukufumana iziphumo ezilungileyo zokuqala, siye sadlulela kuqikelelo oluzenzekelayo.
Indlela edibeneyo
I-VTB iphumeze inkqubo yokubeka iliso evela kwiMicroFocus. Ukusuka apho sithathe ukuqokelelwa kwedatha ukwenzela ukubikezela, inkqubo yokugcina kunye nenkqubo yokunika ingxelo. Enyanisweni, ukubeka iliso kwakusele kukho, konke okwakusele kukongeza i-metrics, imodyuli yokuqikelela kunye nokudala iingxelo ezintsha. Esi sigqibo sixhaswa yikontraka yangaphandle ye-Technoserv, ngoko ke umsebenzi oyintloko ekuphunyezweni kweprojekthi yawela kwiingcali zayo, kodwa sakha imodeli ngokwethu. Inkqubo yokuxela kwangaphambili yenziwe ngokusekwe kuMprofeti, imveliso yomthombo ovulekileyo ophuhliswe nguFacebook. Kulula ukuyisebenzisa kwaye idibanisa ngokulula kunye nezixhobo zethu ezidibeneyo zokubeka iliso kunye neVertica. Xa sithetha nje, inkqubo ihlalutya igrafu yomthwalo kwaye iyikhuphele ngokusekwe kuthotho lweFourier. Kwakhona kunokwenzeka ukongeza ama-coefficients athile emini, athathwe kwimodeli yethu. Iimethrikhi zithathwa ngaphandle kokungenelela komntu, ukubikezelwa ngokuzenzekelayo kuphinda kubalwe kanye ngeveki, kwaye iingxelo ezintsha zithunyelwa kubamkeli.
Le ndlela ichonga imijikelo engundoqo, umzekelo, ngonyaka, ngenyanga, ngekota nangeveki. Iintlawulo zemivuzo kunye nentuthuko, ixesha leeholide, iiholide kunye neentengiso - konke oku kuchaphazela inani leefowuni kwiinkqubo. Kwavela, umzekelo, ukuba imijikelezo ethile idibanisana, kwaye umthwalo oyintloko (75%) kwiinkqubo zivela kwiSithili se-Central Federal. Amaqumrhu asemthethweni kunye nabantu ngabanye baziphatha ngokwahlukileyo. Ukuba umthwalo ovela kwi "physicists" usasazwa ngokulinganayo ngeentsuku zeveki (oku kuninzi kweentengiselwano ezincinci), ngoko kwiinkampani i-99,9% ichithwa kwiiyure zokusebenza, kwaye ukuthengiselana kunokuba mfutshane, okanye kunokucutshungulwa ngaphakathi kweenkampani ezininzi. imizuzu okanye iiyure.
Ngokusekelwe kwidatha efunyenweyo, iintsingiselo zexesha elide zichongwa. Inkqubo entsha ibonakalise ukuba abantu bahamba ngobuninzi kwiinkonzo zebhanki ezikude. Wonke umntu uyayazi le nto, kodwa asizange silindele ubungakanani obunjalo kwaye ekuqaleni asizange sikholelwe kuyo: inani leefowuni kwiiofisi zebhanki liyancipha ngokukhawuleza, kwaye inani leentengiselwano ezikude likhula ngexabiso elifanayo. Ngokufanelekileyo, umthwalo kwiinkqubo nazo ziyakhula kwaye ziya kuqhubeka zikhula. Ngoku siqikelela umthwalo kude kube nguFebruwari 2020. Iintsuku eziqhelekileyo zinokuqikelelwa ngempazamo ye-3%, kunye neentsuku eziphezulu kunye nempazamo ye-10%. Esi sisiphumo esihle.
ngenye into
Njengesiqhelo, oku akuzange kube ngaphandle kobunzima. Indlela yokongeza kusetyenziswa uthotho lweFourier ayiweleli zero kakuhle - siyazi ukuba amaqumrhu asemthethweni avelisa intengiselwano ezimbalwa ngeempelaveki, kodwa imodyuli yokuqikelela ivelisa amaxabiso akude no-zero. Bekusenzeka ukuba zilungiswe ngenkani, kodwa iintonga aziyondlela yethu. Ukongeza, kwafuneka sisombulule ingxaki yokufumana idatha ngokungenabuhlungu kwiinkqubo zomthombo. Ukuqokelelwa rhoqo kolwazi kufuna izixhobo ezinzulu zekhompuyutha, ngoko ke sakha iicache ezikhawulezayo sisebenzisa ukuphindaphinda kwaye sifumane idatha yeshishini kwiikopi. Ukungabikho komthwalo owongezelelweyo kwiinkqubo zenkosi kwiimeko ezinjalo kuyimfuneko yokuthintela.
Imingeni emitsha
Umsebenzi othe ngqo wokubikezela iincopho zasombululwa: akuzange kubekho ukungaphumeleli okunxulumene nomthwalo ogqithisileyo ebhankini ukususela ngoMeyi walo nyaka, kwaye inkqubo entsha yokubikezela idlale indima ebalulekileyo kule nto. Ewe, kwavela ukuba akwanelanga, kwaye ngoku ibhanki ifuna ukuqonda ukuba ziyingozi kangakanani iincopho kuyo. Sifuna uqikelelo kusetyenziswa iimethrikhi ukusuka kuvavanyo lomthwalo, kwaye malunga ne-30% yeenkqubo ezibalulekileyo ezi sele zisebenza, ezinye zisendleleni yokufumana uqikelelo. Kwinqanaba elilandelayo, siya kuqikelela umthwalo kwiinkqubo ezingekho kwiintengiselwano zoshishino, kodwa ngokweziseko ze-IT, oko kukuthi, siya kuhla kwinqanaba elinye. Ukongeza, kufuneka senze ngokuzenzekelayo ukuqokelela kweemetriki kunye nokwakhiwa kweengqikelelo ezisekelwe kuzo, ukwenzela ukuba singajongani nokukhuphela. Akukho nto intle ngayo - siwela nje ukubeka iliso kunye novavanyo lomthwalo ngokuhambelana nezona nkqubo zibalaseleyo zehlabathi.
