SLA, tseem hu ua "kev pom zoo-theem kev pabcuam", yog daim ntawv cog lus lees paub ntawm cov neeg siv khoom thiab cov neeg muab kev pabcuam txog yam uas tus neeg siv khoom yuav tau txais los ntawm kev pabcuam. Nws kuj teev cov nyiaj them thaum lub sij hawm poob vim qhov ua txhaum ntawm tus neeg xa khoom, thiab lwm yam. Hauv qhov tseem ceeb, SLA yog daim ntawv pov thawj nrog kev pab los ntawm qhov chaw muab ntaub ntawv lossis chaw muab kev pabcuam txhawb nqa tus neeg siv khoom uas nws yuav tau txais kev saib xyuas zoo rau txhua txoj hauv kev. Lo lus nug yog tias koj tuaj yeem sau txhua yam koj xav tau hauv SLA, thiab cov xwm txheej sau hauv daim ntawv no tsis tshwm sim ntau dhau. SLA nyob deb ntawm cov lus qhia hauv kev xaiv lub chaw khaws ntaub ntawv thiab koj yeej yuav tsum tsis txhob cia siab rau nws.
Peb txhua tus tau siv los kos npe rau qee yam kev pom zoo uas ua rau qee yam kev lav phib xaub. SLA tsis muaj qhov tshwj xeeb - feem ntau yog cov ntaub ntawv tsis muaj tseeb tshaj plaws uas xav tau. Qhov tsuas yog qhov uas tej zaum tsis muaj txiaj ntsig ntau yog NDA hauv kev txiav txim siab uas lub tswv yim ntawm "kev lag luam zais cia" tsis muaj tiag tiag. Tab sis tag nrho cov teeb meem yog tias SLA tsis pab cov neeg siv khoom hauv kev xaiv tus neeg xa khoom zoo, tab sis tsuas yog cuam tshuam cov plua plav hauv qhov muag.
Dab tsi hosters feem ntau sau rau hauv pej xeem version ntawm SLA uas lawv qhia rau pej xeem? Zoo, thawj kab yog lo lus "kev ntseeg siab" ntawm tus tswv tsev - cov no feem ntau yog cov lej ntawm 98 txog 99,999%. Qhov tseeb, cov lej no tsuas yog ib qho kev tsim zoo nkauj ntawm cov neeg lag luam. Ib zaug dhau los, thaum hosting tseem hluas thiab kim, thiab huab tsuas yog npau suav rau cov kws tshaj lij (nrog rau kev siv dav dav rau txhua tus), qhov taw qhia hosting uptime yog qhov tseem ceeb, tseem ceeb heev. Tam sim no, thaum txhua tus neeg siv khoom siv, ntxiv lossis rho tawm, cov khoom siv tib yam, zaum ntawm tib lub pob txha caj qaum thiab muab cov kev pabcuam tib yam, qhov taw qhia uptime yog qhov tsis tseem ceeb kiag li.
Puas muaj ib qho "tsim" SLA?
Tau kawg, muaj cov qauv zoo tshaj plaws ntawm SLA, tab sis txhua tus ntawm lawv yog cov ntaub ntawv tsis yog cov qauv thiab tau sau npe thiab xaus ntawm tus neeg siv khoom thiab tus neeg muag khoom manually. Ntxiv mus, hom SLA no feem ntau txhawj xeeb txog qee yam kev cog lus ua haujlwm ntau dua li cov kev pabcuam.
Dab tsi yuav tsum muaj SLA zoo suav nrog? Txhawm rau muab nws TLDR, SLA zoo yog cov ntaub ntawv tswj hwm kev sib raug zoo ntawm ob lub koom haum, uas muab ib qho ntawm cov tog neeg (tus neeg siv khoom) siab tshaj plaws tswj cov txheej txheem. Ntawd yog, nws ua haujlwm li cas hauv lub ntiaj teb tiag: muaj ib daim ntawv uas piav qhia txog kev sib cuam tshuam thoob ntiaj teb thiab tswj kev sib raug zoo ntawm ob tog. Nws teev ciam teb, cov cai, thiab hauv nws tus kheej dhau los ua lub zog ntawm kev cuam tshuam uas ob tog tuaj yeem siv tau tag nrho. Yog li, ua tsaug rau qhov tseeb SLA, tus neeg siv khoom tuaj yeem yuam kom tus neeg cog lus ua haujlwm raws li kev pom zoo, thiab nws yuav pab tus neeg cog lus tawm tsam "xav tau" ntawm tus neeg siv khoom ntau dhau uas tsis raug cai los ntawm daim ntawv cog lus. Nws zoo li qhov no: "Peb SLA hais qhov no thiab hais tias, tawm ntawm no, peb ua txhua yam raws li tau pom zoo."
Qhov ntawd yog, "qhov tseeb SLA" = "ib daim ntawv cog lus tsim nyog rau kev pabcuam" thiab muab kev tswj xyuas qhov xwm txheej. Tab sis qhov no tsuas yog ua tau thaum ua haujlwm "raws li sib npaug".
Dab tsi yog sau rau ntawm lub vev xaib thiab dab tsi tos hauv kev muaj tiag yog ob yam sib txawv
Nyob rau hauv dav dav, txhua yam uas peb yuav tham ntxiv yog ib qho kev lag luam tricks thiab kev sim ntawm attiveness.
Yog tias peb coj cov neeg nyiam nyob hauv tsev, ces ib qho kev qhia zoo dua li lwm qhov: 25/8 kev txhawb nqa, server uptime 99,9999999% ntawm lub sijhawm, ib pawg ntawm lawv tus kheej cov ntaub ntawv chaw tsawg kawg hauv Russia. Thov nco ntsoov cov ntsiab lus hais txog cov chaw zov me nyuam, peb mam li rov qab los rau nws me ntsis tom qab. Nyob rau hauv lub sijhawm no, cia peb tham txog qhov kev ua txhaum cai zoo tshaj plaws thiab qhov uas ib tus neeg ntsib thaum nws tus neeg rau zaub mov tseem poob rau hauv "0,0000001% ntawm kev ua tsis tiav."
Nrog rau qhov ntsuas ntawm 98% thiab siab dua, ib qho kev poob qis yog ib qho kev tshwm sim ntawm lub verge ntawm kev ua yuam kev. Cov cuab yeej ua haujlwm thiab kev sib txuas yog nyob ntawd lossis lawv tsis nyob. Koj tuaj yeem siv tus tswv tsev nrog "kev ntseeg siab" kev ntsuam xyuas ntawm 50% (raws li nws tus kheej SLA) rau xyoo tsis muaj teeb meem, lossis koj tuaj yeem "ua tsis tau" ib hlis ib zaug rau ob peb hnub nrog cov txiv neej uas thov 99,99%.
Thaum lub sijhawm poob los (thiab, peb nco ntsoov koj, txhua tus neeg poob rau ib hnub), tom qab ntawd tus neeg siv khoom tau ntsib nrog lub tshuab ua haujlwm sab hauv hu ua "kev txhawb nqa", thiab daim ntawv cog lus kev pabcuam thiab SLA tau tshwm sim. Nws txhais li cas:
- Feem ntau, rau thawj plaub teev ntawm kev poob qis koj yuav tsis tuaj yeem nthuav tawm txhua yam, txawm hais tias qee tus tswv tsev pib rov xam cov nqi (cov nyiaj them poob haujlwm) txij li lub sijhawm sib tsoo.
- Yog tias lub server tsis muaj nyob rau lub sijhawm ntev dua, koj tuaj yeem xa daim ntawv thov kom rov suav cov nqi se.
- Thiab qhov no yog muab hais tias qhov teeb meem tshwm sim vim qhov ua txhaum ntawm tus neeg muag khoom.
- Yog tias koj qhov teeb meem tshwm sim los ntawm ib tus neeg thib peb (ntawm txoj kev loj), nws zoo li "tsis muaj leej twg yuav raug liam" thiab thaum qhov teeb meem raug daws yog qhov teeb meem ntawm koj txoj hmoo.
Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias koj tsis tau nkag mus rau pab pawg engineering, feem ntau koj raug tso tseg los ntawm thawj kab ntawm kev txhawb nqa, uas cuam tshuam nrog koj thaum cov engineers tiag tiag sim kho qhov teeb meem. Suab paub?
Ntawm no, ntau tus neeg cia siab rau SLA, uas, zoo li, yuav tsum tiv thaiv koj los ntawm cov xwm txheej zoo li no. Tab sis, qhov tseeb, cov tuam txhab tsis tshua mus dhau ntawm thaj tsam ntawm lawv tus kheej cov ntaub ntawv lossis muaj peev xwm tig qhov xwm txheej ib puag ncig xws li txo lawv tus kheej cov nqi. Lub luag haujlwm tseem ceeb ntawm SLA yog los txhawb kev ceev faj thiab ua kom ntseeg tau tias txawm tias muaj xwm txheej tsis tau pom dua, "txhua yam yuav zoo." Lub hom phiaj thib ob ntawm SLA yog los sib txuas lus cov ntsiab lus tseem ceeb thiab muab cov chaw muab kev pabcuam rau kev ua haujlwm, uas yog, lub peev xwm los ua qhov tsis ua haujlwm rau ib yam dab tsi uas tus neeg muag khoom yog "tsis muaj lub luag haujlwm."
Nyob rau tib lub sijhawm, cov neeg siv khoom loj, qhov tseeb, tsis quav ntsej txhua yam txog kev them nyiaj hauv SLA. "SLA nyiaj them" yog cov nyiaj rov qab ntawm cov nyiaj hauv cov nqi se hauv kev faib ua feem rau cov khoom siv poob qis, uas yuav tsis suav txog 1% ntawm cov nyiaj tau los thiab lub koob npe nrov. Hauv qhov no, nws yog qhov tseem ceeb tshaj rau cov neeg siv khoom uas cov teeb meem raug daws sai li sai tau tshaj li qee yam ntawm "kev suav nqi se rov qab."
"Ntau lub chaw khaws ntaub ntawv thoob ntiaj teb" yog qhov ua rau muaj kev txhawj xeeb
Peb tau tso qhov xwm txheej nrog ntau cov chaw zov me nyuam ntawm cov chaw muab kev pabcuam hauv ib pawg, vim tias ntxiv rau cov teeb meem kev sib txuas lus pom tseeb tau piav qhia saum toj no, cov teeb meem tsis pom tseeb kuj tshwm sim. Piv txwv li, koj tus neeg muab kev pabcuam tsis muaj kev nkag mus rau "lawv" cov chaw khaws ntaub ntawv.
Hauv peb tsab xov xwm kawg , qhov tseem ceeb ntawm uas yog kev muag khoom ntawm lwm tus neeg lub peev xwm raws li nws tus kheej guise. Feem coob ntawm cov tswv tsev niaj hnub uas thov kom muaj "lawv tus kheej cov ntaub ntawv chaw" hauv ntau thaj tsam yog cov neeg muag khoom siv tus qauv Dawb Label. Ntawd yog, lawv lub cev tsis muaj dab tsi ua nrog cov ntaub ntawv kaw lus hauv Switzerland, Lub Tebchaws Yelemees lossis Netherlands.
Cov kev sib tsoo nthuav heev tshwm sim ntawm no. Koj SLA nrog tus muab kev pabcuam tseem ua haujlwm thiab siv tau, tab sis tus neeg muag khoom tsis tuaj yeem cuam tshuam rau qhov xwm txheej thaum muaj xwm txheej. Nws tus kheej yog nyob rau hauv ib txoj hauj lwm nyob ntawm nws tus kheej lub chaw muag khoom - cov ntaub ntawv chaw, los ntawm lub hwj chim racks twb muas rau muag.
Yog li, yog tias koj muaj nuj nqis tsis yog tsuas yog cov lus zoo nkauj hauv daim ntawv cog lus thiab SLA txog kev ntseeg siab thiab kev pabcuam, tab sis kuj muaj peev xwm ntawm tus neeg muab kev pabcuam los daws teebmeem sai, koj yuav tsum ua haujlwm ncaj qha nrog tus tswv ntawm cov chaw. Qhov tseeb, qhov no suav nrog kev sib cuam tshuam ncaj qha nrog cov ntaub ntawv chaw.
Vim li cas peb tsis xav txog kev xaiv thaum ntau DCs tuaj yeem koom nrog ib lub tuam txhab? Zoo, muaj ntau, tsawg heev xws li tuam txhab uas muag. Ib, ob, peb cov ntaub ntawv me me lossis ib qho loj yog ua tau. Tab sis ib lub kaum os DCs, ib nrab ntawm cov uas nyob rau hauv Lavxias teb sab Federation, thiab lub thib ob nyob rau hauv cov teb chaws Europe, yuav luag tsis yooj yim sua. Qhov no txhais tau tias muaj ntau lub tuam txhab muag khoom muag ntau dua li koj xav. Nov yog ib qho piv txwv yooj yim:
Kwv yees tus naj npawb ntawm Google Cloud cov chaw pabcuam cov ntaub ntawv. Tsuas muaj rau ntawm lawv nyob hauv Europe. Hauv London, Amsterdam, Brussels, Helsinki, Frankfurt thiab Zurich. Ntawd yog, ntawm txhua qhov tseem ceeb ntawm txoj kev loj. Vim hais tias ib lub chaw cov ntaub ntawv yog kim, complex thiab ib qhov project loj heev. Tam sim no nco ntsoov cov tuam txhab hosting los ntawm qhov chaw hauv Moscow nrog "ntau lub chaw cov ntaub ntawv thoob plaws hauv Russia thiab Europe."
Muaj, tau kawg, tsis muaj cov neeg xa khoom zoo uas muaj cov koom tes hauv White Label program, muaj txaus, thiab lawv muab cov kev pabcuam siab tshaj plaws. Lawv ua kom nws muaj peev xwm xauj hauv EU thiab Lavxias Federation ib txhij los ntawm tib lub browser qhov rai, lees txais kev them nyiaj hauv rubles, tsis yog nyiaj txawv teb chaws, thiab lwm yam. Tab sis thaum cov xwm txheej tau piav qhia hauv SLA tshwm sim, lawv dhau los ua tus neeg raug tsim txom ntawm qhov xwm txheej zoo li koj.
Qhov no qhia peb ib zaug ntxiv tias SLA tsis muaj txiaj ntsig yog tias koj tsis muaj kev nkag siab txog tus neeg muag khoom lub koom haum thiab kev muaj peev xwm.
Dab tsi kawg
Lub server sib tsoo ib txwm yog qhov xwm txheej tsis zoo thiab nws tuaj yeem tshwm sim rau txhua tus, nyob qhov twg. Lo lus nug yog qhov kev tswj xyuas ntau npaum li cas koj xav tau. Tam sim no tsis muaj ntau tus neeg muag khoom ncaj qha ntawm lub peev xwm ntawm kev ua lag luam, thiab yog tias peb tham txog cov neeg ua si loj, ces lawv muaj, kuj hais lus, tsuas yog ib qho DC qhov chaw hauv Moscow tawm ntawm kaum tawm thoob plaws Tebchaws Europe uas koj tuaj yeem nkag mus.
Ntawm no, txhua tus neeg siv khoom yuav tsum txiav txim siab rau nws tus kheej: Kuv puas xaiv qhov kev nplij siab tam sim no lossis siv sijhawm thiab siv zog tshawb nrhiav cov ntaub ntawv chaw nyob hauv qhov chaw txais tau hauv Russia lossis Europe, qhov twg kuv tuaj yeem tso kuv cov cuab yeej lossis yuav muaj peev xwm. Hauv thawj kis, cov qauv kev daws teeb meem uas tam sim no nyob rau hauv kev ua lag luam yog tsim nyog. Hauv qhov thib ob, koj yuav tau tawm hws.
Ua ntej tshaj plaws, nws yuav tsum tau txiav txim siab seb tus neeg muag khoom puas yog tus tswv ncaj qha ntawm cov chaw / cov ntaub ntawv chaw. Ntau tus neeg muag khoom siv tus qauv White Label sim lawv qhov zoo tshaj plaws los zais lawv cov xwm txheej, thiab hauv qhov no koj yuav tsum nrhiav qee cov cim qhia tsis ncaj. Piv txwv li, yog "lawv European DCs" muaj qee lub npe tshwj xeeb thiab lub logo uas txawv ntawm lub npe ntawm lub tuam txhab muag khoom. Los yog yog lo lus "cov koom tes" tshwm sim nyob rau hauv ib qho chaw. Cov neeg koom tes = White Label hauv 95% ntawm cov neeg mob.
Tom ntej no, koj yuav tsum paub koj tus kheej nrog cov qauv ntawm lub tuam txhab nws tus kheej, lossis zoo dua, saib cov khoom siv ntawm tus kheej. Ntawm cov chaw zov me nyuam, kev coj ua ntawm excursions lossis tsawg kawg excursion kab lus ntawm lawv tus kheej lub vev xaib lossis blog tsis yog tshiab (peb tau sau xws li ΠΈ ), qhov twg lawv tham txog lawv qhov chaw cov ntaub ntawv nrog cov duab thiab cov lus piav qhia ntxaws.
Nrog ntau lub chaw khaws ntaub ntawv, koj tuaj yeem npaj mus ntsib tus kheej mus rau lub chaw ua haujlwm thiab kev mus ncig ua si rau DC nws tus kheej. Nyob ntawd koj tuaj yeem ntsuas qhov kev txiav txim siab, tej zaum koj yuav muaj peev xwm sib txuas lus nrog ib tus engineers. Nws yog qhov tseeb tias tsis muaj leej twg yuav muab koj ncig xyuas kev tsim khoom yog tias koj xav tau ib tus neeg rau zaub mov rau 300 RUB / hli, tab sis yog tias koj xav tau lub peev xwm loj, ces lub tuam txhab muag khoom yuav ntsib koj zoo. Piv txwv li, peb ua tej kev mus ncig ua si.
Txawm li cas los xij, kev nkag siab zoo thiab kev xav tau kev lag luam yuav tsum tau siv. Piv txwv li, yog tias koj xav tau ib qho chaw faib khoom (qee lub servers nyob hauv Lavxias Federation, lwm qhov hauv EU), nws yuav yooj yim dua thiab muaj txiaj ntsig zoo los siv cov kev pabcuam ntawm cov tswv tsev uas muaj kev koom tes nrog European DCs siv Daim Ntawv Dawb. qauv. Yog tias koj tag nrho cov kev tsim kho vaj tse yuav ua kom muaj zog ntawm ib qho chaw, uas yog, hauv ib lub chaw cov ntaub ntawv, ces nws tsim nyog siv sij hawm los nrhiav tus neeg muag khoom.
Vim tias SLA feem ntau yuav tsis pab koj. Tab sis ua hauj lwm nrog tus tswv ntawm cov chaw, thiab tsis yog ib tug reseller, yuav ua rau kom ceev cov kev daws teeb meem ntawm tej teeb meem.
