V\u00fdzva doby \u2013 projekt b\u011bhem COVIDu\u00a0<\/h2>\n

\nBez dal\u0161\u00edch komplikac\u00ed se ov\u0161em neobe\u0161lo. Samoz\u0159ejm\u011b, jedn\u00edm z p\u0159ek\u00e1\u017eek byl koronavirus.\u00a0<\/p>\n

Pr\u00e1ce se zkomplikovaly, kdy\u017e za\u010dala pandemie, a nebylo mo\u017en\u00e9, aby na m\u00edst\u011b z\u00e1kazn\u00edka byli p\u0159\u00edtomn\u00ed v\u0161ichni specialist\u00e9 zapojen\u00ed do procesu. Na m\u00edsto byli p\u0159\u00edpustn\u00ed pouze zam\u011bstnanci mont\u00e1\u017en\u00ed organizace, a kontrola prob\u00edhala pomoc\u00ed Zoomu \u2013 v n\u011bm byl s\u00ed\u0165ov\u00fd in\u017een\u00fdr ze strany Linxdatacenter, j\u00e1 jako vedouc\u00ed projektu, s\u00ed\u0165ov\u00fd in\u017een\u00fdr ze strany z\u00e1kazn\u00edka, odpov\u011bdn\u00fd za realizaci prac\u00ed, a t\u00fdm prov\u00e1d\u011bj\u00edc\u00ed mont\u00e1\u017en\u00ed pr\u00e1ce.<\/p>\n

B\u011bhem prac\u00ed se objevily neo\u010dek\u00e1van\u00e9 probl\u00e9my, a bylo nutn\u00e9 prov\u00e1d\u011bt \u00fapravy za pochodu. D\u00edky tomu se n\u00e1m poda\u0159ilo rychle p\u0159edch\u00e1zet vlivu lidsk\u00e9ho faktoru (chyby v sch\u00e9matu, chyby p\u0159i ur\u010dov\u00e1n\u00ed stavu aktivity rozhran\u00ed atd.).<\/p>\n

I kdy\u017e se zd\u00e1l distan\u010dn\u00ed form\u00e1t pr\u00e1ce na za\u010d\u00e1tku projektu nezvykl\u00fd, docela rychle jsme si zvykli na nov\u00e9 podm\u00ednky a dostali se k fin\u00e1ln\u00ed f\u00e1zi prac\u00ed.\u00a0<\/p>\n

Spustili jsme do\u010dasnou konfiguraci s\u00edtov\u00fdch nastaven\u00ed pro paraleln\u00ed provoz dvou s\u00ed\u0165ov\u00fdch jader \u2013 star\u00e9ho a nov\u00e9ho \u2013 za \u00fa\u010delem zaji\u0161t\u011bn\u00ed plynul\u00e9ho p\u0159echodu. Nicm\u00e9n\u011b se uk\u00e1zalo, \u017ee nebyl odstran\u011bn jeden zbyte\u010dn\u00fd \u0159\u00e1dek z konfigura\u010dn\u00edho souboru nov\u00e9ho j\u00e1dra, tak\u017ee p\u0159echod se neuskute\u010dnil. To n\u00e1s donutilo str\u00e1vit n\u011bjak\u00fd \u010das hled\u00e1n\u00edm probl\u00e9mu.\u00a0<\/p>\n

Zjistilo se, \u017ee hlavn\u00ed provoz byl p\u0159en\u00e1\u0161en spr\u00e1vn\u011b, zat\u00edmco \u0159\u00eddic\u00ed provoz nedosahoval uzlu p\u0159es nov\u00e9 j\u00e1dro. D\u00edky jasn\u00e9mu rozd\u011blen\u00ed projektu na etapy jsme dovedli celkem rychle ur\u010dit \u010d\u00e1st s\u00edt\u011b, kde do\u0161lo k pot\u00ed\u017e\u00edm, identifikovat probl\u00e9m a vy\u0159e\u0161it ho.\u00a0<\/p>\n

Pokud do\u0161lo k jeho p\u0159eru\u0161en\u00ed, p\u0159ep\u00edna\u010d se stal zcela nedostupn\u00fdm. A pokud bylo k jednomu uplinku p\u0159ipojeno n\u011bkolik p\u0159ep\u00edna\u010d\u016f, katastrofa vy\u0159adila cel\u00fd odd\u011blen\u00ed nebo v\u00fdrobn\u00ed linku podniku.\u00a0<\/p>\n
