Mawa ndi Lachisanu Lachisanu - pama projekiti a pa intaneti izi zikutanthauza kuti padzakhala zochulukira kwambiri patsamba. Ngakhale zimphona sizingathe kulimbana nazo, mwachitsanzo, ndi Amazon pa Prime Day mu 2017.
Tinaganiza zopereka zitsanzo zosavuta zogwirira ntchito ndi seva yeniyeni kuti tipewe zolakwika komanso kuti tisalonjere anthu omwe ali ndi tsamba la 503 kapena, zoipitsitsa, About:blank ndi ERR_CONNECTION_TIMED_OUT. Kwatsala tsiku limodzi lokonzekera.
Kuchulukitsa zothandizira
Webusaiti nthawi zambiri imakhala ndi ma module osiyanasiyana - nkhokwe, seva yapaintaneti, makina osungira. Iliyonse mwa ma module awa imafunikira mitundu yosiyanasiyana komanso kuchuluka kwazinthu. Ndikofunikira kusanthula pasadakhale kuchuluka kwazinthu zomwe zimagwiritsidwa ntchito poyesa kupsinjika ndikuwunika liwiro la disk I / O, nthawi ya purosesa, kukumbukira, ndi bandwidth ya intaneti ya tsamba lanu.
Mayesero a kupsinjika adzakuthandizani kuzindikira zovuta m'dongosolo lanu ndikuzikulitsa pasadakhale. Chifukwa chake, mwachitsanzo, mutha kukulitsa mphamvu ya seva yanu powonjezera malo osungira nthawi yonse yotsatsira, kukulitsa bandwidth yawebusayiti kapena kuwonjezera RAM ya seva yeniyeni. Mukatha kukwezedwa, mutha kubweza zonse momwe zinalili, izi zimachitika muakaunti yanu popanda kulumikizana ndi chithandizo chaukadaulo ndipo zimatenga mphindi zingapo, koma ndi bwino kuchita izi pasadakhale komanso nthawi yanthawi yochepa yamakasitomala patsamba.
Dzitetezeni ku DDoS pasadakhale
Mawebusaiti amawonongeka pamasiku ogulitsa osati chifukwa cha kuwonjezeka kwa makasitomala, komanso chifukwa cha kuukira kwa DDoS. Atha kukonzedwa ndi omwe akuukira omwe akufuna kuwongolera kuchuluka kwa magalimoto anu kuzinthu zawo zachinyengo.
Kuukira kwa DDoS kukuchulukirachulukira tsiku lililonse. Obera amagwiritsa ntchito njira zosiyanasiyana, pogwiritsa ntchito zida zonse za DDoS ndikuwukira zowopsa za pulogalamu. Nthawi zambiri, kuukira kumatsagana ndi kuyesa kuthyolako tsambalo.
Apa ndikofunikanso kukonzekera pasadakhale ndikulumikiza adilesi ya IP yotetezedwa kuti isawonongedwe ndi seva yanu. Ku UltraVDS timateteza ma seva osati pambuyo powukiridwa, koma usana ndi usiku ndipo timapirira mpaka 1.5 Tbps! Kuteteza ma seva ku DDoS kuukira, zosefera zingapo zimagwiritsidwa ntchito, zolumikizidwa ndi njira ya intaneti yokhala ndi bandwidth yayikulu mokwanira. Zosefera nthawi zonse zimasanthula kuchuluka kwa magalimoto, ndikuzindikira zolakwika ndi zochitika zachilendo zapaintaneti. Njira zomwe sizinali zodziwika bwino zomwe zawunikidwa zikuphatikiza njira zonse zowukira zomwe zimadziwika pano, kuphatikiza zomwe zimagwiritsidwa ntchito pogwiritsa ntchito ma botnets.
Kuti mulumikizane ndi adilesi yotetezedwa ku seva yeniyeni, muyenera kutumiza pempho ku chithandizo cha wothandizira pasadakhale.
Limbikitsani kutsitsa kwatsamba
Panthawi yokwezedwa, katundu pa maseva amawonjezeka, ndipo zithunzi ndi makhadi azinthu zimatenga nthawi yayitali kuti zitheke pamasamba. Komanso, kutsitsa masamba kumakhala kovuta kwambiri ndi machitidwe osiyanasiyana, malaibulale a JS, ma module a CSS, ndi zina zotero. Wothandizira kasitomala akhoza kusiya tsambalo osalandira yankho kuchokera patsambalo, ngakhale zoperekazo zili zabwino kuposa za omwe akupikisana nawo. Kuti muwone kuthamanga kwa tsamba, tikupangira kugwiritsa ntchito Google DevTools.
Network Delivery Network (CDN) ikhoza kuthandizira kutsitsa masamba. CDN ndi netiweki yogawidwa yomwe ili ndi ma caching node - malo okhala, amatha kupezeka padziko lonse lapansi. Mukachezera tsambalo, kasitomala alandila zokhazikika osati kuchokera ku seva yanu, koma kuchokera kugawo lomwe lili gawo la netiweki ya CDN ndipo ili pafupi ndi iyo. Mwa kufupikitsa njira pakati pa seva ndi kasitomala, zomwe zili patsamba zimadzaza mwachangu.
Mutha kukhazikitsa netiweki ya CDN nokha ngati muli ndi VDS pa Windows Server Core 2019; kuti muchite izi, gwiritsani ntchito zida zomangidwira pamakina ogwiritsira ntchito monga: Active Directory, DFS, IIS, WinAcme, RSAT. Mukhozanso kugwiritsa ntchito njira zokonzekera, mwachitsanzo, CDN yochokera ku Cloudflare ikhoza kuthetsa vutoli mofulumira komanso motchipa. Kuphatikiza apo, dongosololi lili ndi zina zowonjezera: DNS, HTML compression, CSS, JS, mfundo zambiri zopezeka.
Zabwino zonse ndi malonda anu.
Lachisanu Lachisanu mu UltraVDS
Sitinanyalanyazenso kuchotsera kwachikhalidwe patsikuli ndikupatsa ogwiritsa ntchito a Habr nambala yotsatsira BlackFr ndikuchotsera 15% pamaseva athu onse kuyambira Novembara 28 mpaka Disembala 2 kuphatikiza.
Mwachitsanzo, seva pamitengo ya UltraLight yokhala ndi 1 CPU core, 500MB ya RAM ndi 10GB ya disk space yomwe ikuyenda ndi Windows Server Core 2019 ingagulidwe pogwiritsa ntchito nambala yotsatsira BlackFr ndi kuchotsera kowonjezera kwa 30% kwa chaka kwa ma ruble 55 okha pamwezi, kotero kuchotsera kwathunthu kudzakhala 45% yamtengo wapano.
ndi kampani yamakono yopereka mitambo; mazana a mabungwe akuluakulu amagwira ntchito nafe, kuphatikizapo mabanki odziwika bwino, ogulitsa katundu, makampani omanga ndi opanga mankhwala.
