Tsis ntev ua ntej hnub so Xyoo Tshiab, thawj pawg khoom siv tuaj txog rau peb. Qhov no ua rau nws muaj peev xwm xa tau qee lub tshuab ntawm cov khoom siv tiag tiag. Txij li thaum tsis yog txhua yam tuaj txog, peb txuas cov khoom siv hloov pauv, cov khoom siv uas peb tau tswj xyuas kom pom zoo nrog cov neeg muag khoom thiab cov neeg xa khoom. Peb tau txais qhov seem ntawm lub hom phiaj infrastructure ntawm theem kawg.
Yuav kom ua tau raws li lub sijhawm kawg, peb cov kws tsim khoom yuav tsum tau txi lub Xyoo Tshiab hnub so thiab pib ua haujlwm ntawm kev npaj cov phiaj xwm phiaj xwm rau Lub Ib Hlis 2, nyob rau hauv nruab nrab ntawm cov hnub so. Yog, qee zaum qhov no tshwm sim thaum nws raug hluav taws thiab tsis muaj lwm txoj kev xaiv. Ntawm ceg txheem ntseeg yog qhov kev ua tau zoo ntawm cov tshuab uas lub neej ntawm kev lag luam nyob ntawm.
Qhov kev txiav txim dav dav ntawm kev tsiv teb tsaws zoo li no: ua ntej, qhov tseem ceeb tshaj plaws (kev txhim kho toj roob hauv pes, kev sim toj roob hauv pes), tom qab ntawd cov tshuab tsim khoom. Qhov kawg theem ntawm kev tsiv teb tsaws tau tshwm sim thaum lub Ib Hlis lig thiab lub Ob Hlis thaum ntxov.
Txoj kev tsiv teb tsaws chaw tau npaj mus rau feeb. Qhov no yog ib txoj kev npaj txiav tawm nrog cov npe ntawm txhua txoj haujlwm, lub sijhawm ua tiav thiab cov neeg muaj lub luag haujlwm. Tag nrho cov kauj ruam twb tau ua tiav nyob rau hauv qhov kev xeem tsiv teb tsaws, yog li nyob rau hauv kev tsiv teb tsaws chaw nws tsuas yog tsim nyog los ua raws li txoj kev npaj thiab tswj cov txheej txheem.
Kev tsiv teb tsaws tau ua tiav hauv ntau theem. Muaj ob lub tshuab hauv txhua theem.
Qhov tshwm sim ntawm peb lub hlis sprint yog ib qho system uas ua haujlwm tag nrho hauv CROC data center. Feem ntau, qhov txiaj ntsig zoo tau ua tiav los ntawm kev ua haujlwm hauv pab pawg; kev koom tes thiab kev mob siab rau txhua tus neeg koom hauv cov txheej txheem yog qhov siab tshaj plaws.
Lub luag haujlwm ntawm tus neeg siv khoom hauv qhov project
Kev sib txuas lus nrog tus neeg muab kev pabcuam peb cov neeg siv khoom tau tawm mus tsis yooj yim. Qhov no yog to taub; lawv yog tus kawg ntawm cov npe ntawm cov neeg txaus siab rau kev ua tiav ntawm qhov project. Cov neeg siv khoom tau ua haujlwm ntawm kev nce ntxiv thiab pedaling tag nrho cov teeb meem kev sib txuas lus thiab daws qhov no 100500%. Ua tsaug tshwj xeeb rau nws rau qhov no. Yog tias tsis muaj kev koom tes hauv cov txheej txheem, qhov tshwm sim ntawm qhov project yuav txawv kiag li.
Vim lub formalization ntawm cov txheej txheem nyob rau sab ntawm "yav dhau los" tus neeg muab kev pab, kev txhawb nqa infrastructure tau ua los ntawm cov kws tshwj xeeb uas tau hais deb ntawm cov teeb meem, thaum lub sijhawm ntawd tseem yog lawv cov neeg siv khoom. Piv txwv li, cov txheej txheem ntawm kev xa tawm tib lub database yuav siv sij hawm los ntawm ib teev mus rau tsib. Tom qab ntawd nws zoo li qhov no yog qee yam kev ua khawv koob, ib qho zais cia uas tsis tau qhia rau peb. Tej zaum cov kws tshaj lij kev pabcuam txhawb nqa kev xav hauv lub sijhawm no, tsis nco qab tias qhov chaw nyob deb tebchaws Russia muaj sijhawm kawg, cov kws ua haujlwm tsis muaj xyoo tshiab zaub xam lav, cov neeg siv khoom tau quaj thiab kev txom nyem ...
Qhov project tshwm sim
Cov kauj ruam kawg ntawm kev tsiv teb tsaws yog kev hloov ntawm cov tshuab rau kev tu.
