Sutra je \"Crni Petak\" \u2014 za internetske projekte to zna\u010di da \u0107e biti vr\u0161ne optere\u0107enja na web-stranicama. \u010cak ni giganti to ne mogu izdr\u017eati, na primjer, dogodilo se<\/a><\/noindex> s Amazonom na Prime Day 2017. godine.\u00a0<\/p>\n

\"Pre\u017eivjet<\/a><\/noindex><\/p>\n

Odlu\u010dili smo navesti nekoliko jednostavnih primjera rada s virtualnim serverima kako bismo izbjegli gre\u0161ke i ne do\u017eivjeli ljude s 503 stranicom ili, \u0161to je jo\u0161 gore, About:blank i ERR_CONNECTION_TIMED_OUT. Ostao je jo\u0161 samo jedan dan za pripremu.
\n<\/a><\/noindex><\/p>\n

Skaliranje resursa<\/h2>\n

\nWeb-stranica se obi\u010dno sastoji od razli\u010ditih modula \u2014 baza podataka, web-servera, sustava ke\u0161iranja. Svaki od tih modula zahtijeva razli\u010dite vrste i koli\u010dine resursa. Potrebno je unaprijed provesti analizu potro\u0161nje resursa putem stres-testova i procijeniti brzinu ulaza-izlaza diska, procesorsko vrijeme, memoriju, \u0161irinu internetske veze va\u0161e stranice.<\/p>\n

Stres-testovi \u0107e pomo\u0107i u odre\u0111ivanju uskih grla va\u0161eg sustava i unaprijed ih skalirati. Na primjer, mo\u017eete pobolj\u0161ati mo\u0107 va\u0161eg servera pove\u0107anjem prostora na tvrdom disku tijekom promocije, pro\u0161iriti propusnost weba ili pove\u0107ati RAM virtualnog servera. Nakon promocije mo\u017eete sve vratiti kako je bilo, to se radi u korisni\u010dkom su\u010delju bez potrebe za kontaktom s tehni\u010dkom podr\u0161kom i traje nekoliko minuta, ali najbolje je to u\u010diniti unaprijed i u vremenima minimalne aktivnosti korisnika na stranici.<\/p>\n

Unaprijed se za\u0161tititi od DDoS napada<\/h2>\n

\nWeb-stranice padaju u danima rasprodaja ne samo zbog pove\u0107anja broja korisnika, ve\u0107 i zbog DDoS napada. Mogu ih organizirati zlonamjernici koji \u017eele preusmjeriti va\u0161 promet na svoje phishing resurse.\u00a0<\/p>\n

DDoS napadi postaju sve sofisticiraniji. Hakeri koriste razli\u010dite pristupe, istovremeno pribjegavaju\u0107i DDoS napadima i napadima na ranjivosti aplikacija. U ve\u0107ini slu\u010dajeva napadi su pra\u0107eni poku\u0161ajima hakiranja stranice.<\/p>\n

Tako\u0111er je va\u017eno unaprijed se pripremiti i povezati za va\u0161 server IP adresu za\u0161ti\u0107enu od napada. U UltraVDS-u \u0161titimo servere ne samo kada do\u0111e do napada, ve\u0107 ih kontinuirano i stabilno \u0161titimo od napada do 1.5 Tbps! Za za\u0161titu servera od DDoS napada koristi se niz filtera povezanih s internet kanalom s dovoljno velikim propusnim optere\u0107enjem. Filteri sequencijalno analiziraju prolazni promet, otkrivaju\u0107i anomalije i neobi\u010dnu mre\u017enu aktivnost. Me\u0111u analiziranim obrascima neobi\u010dnog prometa su sve do sada poznate metode napada, uklju\u010duju\u0107i one izvr\u0161ene putem distribuiranih bot mre\u017ea.<\/p>\n

Za povezivanje za\u0161ti\u0107ene adrese s virtualnim serverom potrebno je unaprijed poslati zahtjev podr\u0161ci pru\u017eatelja usluge.<\/p>\n

Ubrzajte u\u010ditavanje stranice<\/h2>\n

\nTijekom promocije optere\u0107enje na serverima se pove\u0107ava, a slike i kartice proizvoda na stranicama po\u010dinju se dugo u\u010ditavati. Osim toga, u\u010ditavanje stranica ote\u017eavaju razni frameworkovi, JS biblioteke, CSS moduli i sli\u010dno. Potencijalni kupac mo\u017ee napustiti stranicu bez odgovora sa sajta, \u010dak i ako je ponuda povoljnija od konkurencije. Preporu\u010dujemo upotrebu Google DevTools za provjeru brzine u\u010ditavanja stranica.<\/p>\n

Mre\u017ea za isporuku sadr\u017eaja (Content Delivery Network, CDN) mo\u017ee pomo\u0107i u ubrzavanju u\u010ditavanja stranica. CDN je geografski distribuirana mre\u017ea koja se sastoji od ke\u0161iranih \u010dvori\u0161ta \u2014 to\u010daka prisutnosti, koje se nalaze \u0161irom svijeta. Kada korisnik pristupi web stranici, dobit \u0107e stati\u010dki sadr\u017eaj ne s va\u0161eg servera, ve\u0107 s onog koji pripada CDN mre\u017ei i koji je bli\u017ei njemu. Zahvaljuju\u0107i skra\u0107enju rute izme\u0111u servera i klijenta, podaci na web stranici u\u010ditavaju se br\u017ee.<\/p>\n

CDN mre\u017eu mo\u017eete postaviti sami ako imate VDS na Windows Server Core 2019, koriste\u0107i ugra\u0111ena sredstva operativnog sustava kao \u0161to su: Active Directory, DFS, IIS, WinAcme, RSAT. Tako\u0111er se mogu koristiti gotova rje\u0161enja; na primjer, CDN od Cloudflare mogao bi brzo i jeftino rije\u0161iti problem. Osim toga, ovaj sustav ima dodatne mogu\u0107nosti: DNS, kompresiju HTML, CSS, JS, mnogo to\u010daka prisutnosti.<\/p>\n

\u017delimo vam uspje\u0161ne prodaje.<\/p>\n
