Jak WEDOS WebSite roste<\/h3>\n

Slu\u017eba WEDOS WebSite n\u00e1m d\u011bl\u00e1 opravdu radost. Na jej\u00ed spu\u0161t\u011bn\u00ed byl opravdu velk\u00fd tlak ze strany na\u0161ich z\u00e1kazn\u00edk\u016f, kte\u0159\u00ed se j\u00ed nemohli do\u010dkat. Tentokr\u00e1t jsem \u0161li cestou „Progress Over Perfection“<\/em>, v\u0161e spustili v testovac\u00edm re\u017eimu a postupn\u011b ladili a dopl\u0148ovali jednotliv\u00e9 v\u011bci.<\/p>\n

Jak u\u017e jsme zm\u00ednili, v \u00fanoru p\u0159ibyly kontaktn\u00ed formul\u00e1\u0159e. Tato funkcionalita byla hodn\u011b popt\u00e1v\u00e1na. V\u00edme, \u017ee t\u0159eba u WordPress s n\u00ed maj\u00ed z\u00e1kazn\u00edci \u010dasto probl\u00e9my. Kontaktn\u00ed formul\u00e1\u0159e je nutn\u00e9 spr\u00e1vn\u011b zabezpe\u010dit, aby nedoch\u00e1zelo k jejich zneu\u017e\u00edv\u00e1n\u00ed. U WebSite se o to kompletn\u011b star\u00e1me my.<\/p>\n

V b\u0159eznu jsme pro WebSite ve WebSite p\u0159ipravili vlastn\u00ed produktovou str\u00e1nku. Najdete ji na wedos.website<\/a> \ud83d\ude42 . V\u0161e je tedy vyrobeno v na\u0161em editoru WEDOS WebSite<\/a>.<\/p>\n

Nastal tak\u00e9 \u010das po\u0159\u00e1dn\u011b slu\u017ebu vyhodnotit, abychom v\u011bd\u011bli, kolik vlastn\u011b web\u016f na n\u00ed doopravdy vznik\u00e1 a jak jsou t\u0159eba rychl\u00e9.

Aktu\u00e1ln\u011b je aktivn\u00edch 997 web\u016f<\/strong> na WEDOS WebSite. Tj. jedn\u00e1 se o dom\u00e9ny, p\u0159i\u0159azen\u00e9 k slu\u017eb\u011b WEDOS WebSite, sm\u011b\u0159uj\u00edc\u00ed na servery, kde je provozov\u00e1na slu\u017eba a kter\u00e9 vr\u00e1tili alespo\u0148 1 request na hlavn\u00ed str\u00e1nku se stavov\u00fdm k\u00f3dem 200.<\/p>\n

WEDOS WebSite jsme postavili tak, abyste na ni mohli provozovat weby s milionovou n\u00e1v\u0161t\u011bvnost\u00ed. Proto jsme kladli d\u016fraz na rychlost. B\u011bhem sledovan\u00fdch 7 dn\u016f byla pr\u016fm\u011brn\u00e1 rychlost vygenerov\u00e1n\u00ed str\u00e1nky serverem 14 ms<\/strong>, median <\/strong>pak 13 ms<\/strong>.<\/p>\n

Pro srovn\u00e1n\u00ed v dubnu minul\u00e9ho roku jsme d\u011blali rozs\u00e1hl\u00fd pr\u016fzkum v\u0161ech str\u00e1nek na NoLimit a WMS<\/a> a tam n\u00e1m vy\u0161la n\u00e1sleduj\u00edc\u00ed \u010d\u00edsla.<\/p>\n

I z toho je vid\u011bt, jak rychl\u00fd WebSite je. A\u017e odlad\u00edme onpage, tak u\u017e nebude m\u00edt chybu \ud83d\ude42<\/p>\n

DDoS \u00fatok aneb vyzkou\u0161\u00edme co WebSite vydr\u017e\u00ed<\/h4>\n

Shodou okolnost\u00ed na dom\u00e9nu jednoho na\u0161eho z\u00e1kazn\u00edka byl veden pom\u011brn\u011b siln\u00fd DDoS \u00fatok. Byl podobn\u00fd t\u011bm chytr\u00fdm, kter\u00e9 jsme popisovali v \u010dl\u00e1nku P\u0159ich\u00e1z\u00ed vlna nov\u00fdch a z\u00e1ke\u0159n\u00fdch \u00fatok\u016f a WEDOS je na n\u011b p\u0159ipraven\u00fd<\/a>. Jednalo se o botnet, kter\u00fd \u00fato\u010dil ze s\u00edt\u00ed mobiln\u00edch oper\u00e1tor\u016f z Afriky a Bl\u00edzk\u00e9ho v\u00fdchodu. \u0160patn\u011b detekovateln\u00fd, kter\u00fd pro\u0161el z velk\u00e9 \u010d\u00e1sti i d\u00edky tomu, \u017ee nep\u00e1chal \u017e\u00e1dnou \u0161kodu. Nesepnuly se tedy n\u011bkter\u00e9 filtry.<\/p>\n

Vzhledem k tomu, \u017ee nep\u00e1chal \u017e\u00e1dn\u00e9 \u0161kody a servery s WebSite nejevili \u017e\u00e1dn\u00e9 zn\u00e1mky zpomalen\u00ed, tak jsme alespo\u0148 vyzkou\u0161eli co WebSite ut\u00e1hne. Vybrali jsme den 24. b\u0159ezna 2021, kdy byly \u00fatoky nejsiln\u011bj\u0161\u00ed. Celkem se jednalo o 2.814.931 request\u016f<\/strong>, kter\u00e9 pro\u0161ly (\u010d\u00e1st byla zablokov\u00e1na SYN filtrem za neplechy jinde).<\/p>\n

\"\"<\/a><\/p>\n

V\u0161echny requesty pro\u0161ly na server s WebSite a zapsaly se do logu bez citeln\u00e9ho zpomalen\u00ed. Na grafu vid\u00edte po\u010det request\u016f za hodinu. \u0160pi\u010dka byla mezi 16 – 17 hodinou, kdy dos\u00e1hla 368.590 request\u016f za hodinu, co\u017e je v pr\u016fm\u011bru 6143 request\u016f za minutu. WebSite to ust\u00e1l bez \u00fahony.<\/p>\n

Nicm\u00e9n\u011b v tomto p\u0159\u00edpad\u011b se jednalo pouze o requesty na konkr\u00e9tn\u00ed str\u00e1nku. K samotn\u00e9 n\u00e1v\u0161t\u011bv\u011b nedo\u0161lo. Nestahoval se tedy CSS soubor, JavaScript, obr\u00e1zky atd. Na druhou stranu tyto soubory jsou na na\u0161\u00ed provizorn\u00ed CDN, kterou do budoucna nahrad\u00ed WEDOS AnyCast CDN.<\/p>\n

A\u010dkoliv je u varianty WEDOS WebSite profi naps\u00e1no, \u017ee je vhodn\u00e1 pro n\u00e1v\u0161t\u011bvnost do 100.000 n\u00e1v\u0161t\u011bv za den, tak si trouf\u00e1me \u0159\u00edct, \u017ee i milion bychom zvl\u00e1dli \ud83d\ude42<\/p>\n
