Tag kis yog Dub Friday - rau cov haujlwm hauv Is Taws Nem qhov no txhais tau hais tias yuav muaj qhov siab tshaj plaws ntawm qhov chaw. Txawm tias cov neeg loj heev yuav tsis tuaj yeem tiv taus lawv, piv txwv li, nrog Amazon ntawm Prime Day hauv 2017.
Peb tau txiav txim siab muab qee qhov piv txwv yooj yim ntawm kev ua haujlwm nrog virtual server txhawm rau zam kev ua yuam kev thiab tsis tos txais cov neeg nrog 503 nplooj ntawv lossis, txawm tias phem dua, Hais txog: dawb paug thiab ERR_CONNECTION_TIMED_OUT. Tseem muaj ib hnub los npaj.
Scaling cov peev txheej
Lub vev xaib feem ntau muaj cov qauv sib txawv - database, web server, caching system. Txhua ntawm cov modules no yuav tsum muaj ntau hom thiab cov peev txheej. Nws yog ib qho tsim nyog los tshuaj xyuas ua ntej cov nyiaj tau txais los ntawm kev siv cov kev ntsuas kev ntxhov siab thiab ntsuas lub disk I / O ceev, lub sijhawm ua haujlwm, nco, thiab Internet bandwidth ntawm koj qhov chaw.
Kev ntsuam xyuas kev ntxhov siab yuav pab koj txheeb xyuas cov kev tsis sib haum xeeb hauv koj lub cev thiab ntsuas lawv ua ntej. Yog li, piv txwv li, koj tuaj yeem txhim kho lub zog ntawm koj cov neeg rau zaub mov los ntawm kev nce qhov chaw hard drive rau lub sijhawm ntawm kev nce qib, nthuav lub vev xaib bandwidth lossis nce RAM ntawm virtual server. Tom qab kev nce qib, koj tuaj yeem rov qab txhua yam raws li nws tau ua, qhov no yog ua tiav hauv koj tus kheej tus account yam tsis tau hu rau kev txhawb nqa thiab siv sijhawm li ob peb feeb, tab sis nws yog qhov zoo dua los ua qhov no ua ntej thiab thaum lub sijhawm ua haujlwm ntawm cov neeg siv khoom tsawg tsawg ntawm lub xaib.
Tiv thaiv koj tus kheej los ntawm DDoS tawm tsam ua ntej
Cov vev xaib sib tsoo thaum hnub muag tsis yog vim qhov nce ntawm cov neeg siv khoom, tab sis kuj yog vim DDoS tawm tsam. Lawv tuaj yeem raug teeb tsa los ntawm cov neeg tawm tsam uas xav hloov koj lub tsheb mus rau lawv cov peev txheej phishing.
DDoS kev tawm tsam tau dhau los ua ntau dua txhua hnub. Hackers siv ntau txoj hauv kev, siv ob qho tib si DDoS tawm tsam thiab tawm tsam ntawm daim ntawv thov qhov tsis zoo. Feem ntau, kev tawm tsam yog nrog los ntawm kev sim hack lub xaib.
Ntawm no nws tseem ceeb heev rau kev npaj ua ntej thiab txuas tus IP chaw nyob tiv thaiv los ntawm kev tawm tsam rau koj lub server. Ntawm UltraVDS peb tiv thaiv cov servers tsis yog tom qab kev tawm tsam, tab sis ib ncig ntawm lub moos thiab tsis tu ncua tiv thaiv kev tawm tsam txog 1.5 Tbps! Txhawm rau tiv thaiv cov servers los ntawm DDoS tawm tsam, siv cov ntxaij lim dej ntau, txuas nrog Internet channel nrog lub bandwidth loj txaus. Cov lim dej tsis tu ncua txheeb xyuas kev hla dhau, txheeb xyuas qhov tsis txaus ntseeg thiab kev ua haujlwm tsis sib xws hauv network. Cov qauv kev tsheb tsis yog tus qauv txheeb xyuas suav nrog txhua txoj kev tawm tsam tam sim no, suav nrog cov uas tau siv los ntawm kev faib botnets.
Txhawm rau txuas qhov chaw nyob tiv thaiv mus rau lub server virtual, koj yuav tsum xa daim ntawv thov mus rau tus kws kho mob cov kev pabcuam ua ntej.
Ceev qhov chaw thauj khoom
Thaum lub sijhawm ntawm kev tshaj tawm, kev thauj khoom ntawm cov servers nce, thiab cov duab thiab cov ntawv teev khoom siv sijhawm ntev los thauj khoom ntawm cov vev xaib. Tsis tas li ntawd, kev thauj cov nplooj ntawv yog qhov nyuaj dua los ntawm ntau lub moj khaum, JS cov tsev qiv ntawv, CSS modules, thiab lwm yam. Ib tus neeg siv khoom muaj peev xwm tuaj yeem tawm ntawm nplooj ntawv yam tsis tau txais cov lus teb los ntawm lub xaib, txawm tias qhov kev thov zoo dua li cov neeg sib tw. Txhawm rau txheeb xyuas nplooj ntawv nrawm, peb xav kom siv Google DevTools.
Ib Lub Tuam Txhab Xa Khoom (CDN) tuaj yeem pab ua kom nrawm nplooj ntawv thauj khoom. CDN yog ib qho chaw sib faib hauv thaj chaw uas muaj caching nodes - cov ntsiab lus ntawm qhov muaj nyob, lawv tuaj yeem nyob thoob plaws ntiaj teb. Thaum mus xyuas lub xaib, tus neeg siv yuav tau txais cov ntsiab lus zoo li qub tsis yog los ntawm koj lub server, tab sis los ntawm ib feem ntawm CDN network thiab nyob ze rau nws. Los ntawm txoj kev luv luv ntawm cov neeg rau zaub mov thiab cov neeg siv khoom, cov ntaub ntawv ntawm lub xaib yuav nrawm dua.
Koj tuaj yeem teeb tsa CDN network koj tus kheej yog tias koj muaj VDS ntawm Windows Server Core 2019; txhawm rau ua qhov no, siv cov cuab yeej tsim los rau hauv kev ua haujlwm xws li: Active Directory, DFS, IIS, WinAcme, RSAT. Koj tuaj yeem siv cov kev daws teeb meem npaj txhij, piv txwv li, CDN los ntawm Cloudflare tuaj yeem daws qhov teeb meem sai dua thiab pheej yig dua. Ntxiv rau, qhov system no muaj cov yam ntxwv ntxiv: DNS, HTML compression, CSS, JS, ntau cov ntsiab lus ntawm qhov muaj nyob.
Hmoov zoo nrog koj qhov muag.
