Dobr\u00e1 dostupnost se nepozn\u00e1 podle hezk\u00e9 v\u011bty ve smlouv\u011b<\/h2>\n\n

Ka\u017ed\u00fd poskytovatel um\u00ed \u0159\u00edct, \u017ee nab\u00edz\u00ed vysokou dostupnost. Pro firmu ale nen\u00ed rozhoduj\u00edc\u00ed samotn\u00fd slib. D\u016fle\u017eit\u00e9 je, co p\u0159esn\u011b znamen\u00e1 v praxi, jak se m\u011b\u0159\u00ed a co se stane, kdy\u017e slu\u017eba nefunguje podle o\u010dek\u00e1v\u00e1n\u00ed.<\/p>\n\n

Pr\u00e1v\u011b od toho existuje Service Level Agreement (SLA). Jde o dohodu o \u00farovni poskytovan\u00e9 slu\u017eby, kter\u00e1 m\u00e1 p\u0159ev\u00e9st obecnou p\u0159edstavu o spolehlivosti do konkr\u00e9tn\u00edch z\u00e1vazk\u016f. Pokud je napsan\u00e1 dob\u0159e, pom\u00e1h\u00e1 ob\u011bma stran\u00e1m: z\u00e1kazn\u00edk v\u00ed, co m\u016f\u017ee o\u010dek\u00e1vat, a poskytovatel m\u00e1 jasn\u011b popsan\u00fd provozn\u00ed r\u00e1mec.<\/p>\n\n

Pokud je SLA jen form\u00e1ln\u00ed dokument, probl\u00e9m se uk\u00e1\u017ee a\u017e p\u0159i incidentu. A to je nejhor\u0161\u00ed mo\u017en\u00fd okam\u017eik na vysv\u011btlov\u00e1n\u00ed odpov\u011bdnost\u00ed.<\/p>\n\n

Co m\u00e1 SLA v datov\u00e9m centru obsahovat<\/h2>\n\n

SLA by m\u011blo odpov\u00eddat na n\u011bkolik praktick\u00fdch ot\u00e1zek. Jak\u00e1 dostupnost je popsan\u00e1? Jak\u00e9 typy incident\u016f existuj\u00ed? Jak rychle poskytovatel reaguje? Kdy se probl\u00e9m eskaluje? Kdo za co odpov\u00edd\u00e1? Jak se incident uzav\u00edr\u00e1 a vyhodnocuje?<\/p>\n\n

U datov\u00e9ho centra je zvl\u00e1\u0161\u0165 d\u016fle\u017eit\u00e9, aby Service Level Agreement nebyl odtr\u017een\u00fd od re\u00e1ln\u00e9ho provozu. Reak\u010dn\u00ed \u010das m\u00e1 hodnotu jen tehdy, kdy\u017e za n\u00edm stoj\u00ed t\u00fdm, proces a fyzick\u00e1 schopnost zas\u00e1hnout. Nep\u0159etr\u017eit\u00fd dohled m\u00e1 hodnotu jen tehdy, kdy\u017e na n\u011bj navazuj\u00ed jasn\u00e9 postupy.<\/p>\n\n

V SafeDX se SLA op\u00edr\u00e1 o m\u011b\u0159iteln\u00e9 parametry, definovan\u00e9 priority incident\u016f, reak\u010dn\u00ed \u010dasy, eskala\u010dn\u00ed proces a jasnou hranici odpov\u011bdnosti. To je rozd\u00edl mezi obecn\u00fdm p\u0159\u00edslibem a provozn\u00edm z\u00e1vazkem.<\/p>\n\n

Nejv\u011bt\u0161\u00ed rozd\u00edl se uk\u00e1\u017ee mimo pracovn\u00ed dobu<\/h2>\n\n

Firemn\u00ed IT neb\u011b\u017e\u00ed jen od pond\u011bl\u00ed do p\u00e1tku. Syst\u00e9my obsluhuj\u00ed v\u00fdrobu, z\u00e1kazn\u00edky, obchod, intern\u00ed procesy i automatizovan\u00e9 \u00falohy. Probl\u00e9m m\u016f\u017ee p\u0159ij\u00edt v noci, o v\u00edkendu nebo ve sv\u00e1tek.<\/p>\n\n

Proto nesta\u010d\u00ed v\u011bd\u011bt, \u017ee datov\u00e9 centrum m\u00e1 podporu. Firma pot\u0159ebuje v\u011bd\u011bt, co se stane, kdy\u017e je pot\u0159eba \u0159e\u0161it v\u011bc hned. Je na m\u00edst\u011b technik? Funguje dohled nep\u0159etr\u017eit\u011b? Existuje jasn\u00fd postup? Je odpov\u011bdnost konkr\u00e9tn\u00ed, nebo se bude probl\u00e9m p\u0159ed\u00e1vat mezi lidmi?<\/p>\n\n

Datov\u00e9 centrum, kter\u00e9 m\u00e1 fungovat jako z\u00e1zem\u00ed pro firemn\u00ed IT, mus\u00ed b\u00fdt p\u0159ipraven\u00e9 pr\u00e1v\u011b na tyto okam\u017eiky. B\u011b\u017en\u00fd provoz je d\u016fle\u017eit\u00fd, ale skute\u010dn\u00e1 \u00farove\u0148 slu\u017eby se ukazuje ve chv\u00edli, kdy n\u011bco p\u0159estane b\u00fdt b\u011b\u017en\u00e9.<\/p>\n\n

Dobr\u00e9 SLA nen\u00ed obrana poskytovatele ani formalita pro n\u00e1kupn\u00ed odd\u011blen\u00ed. Je to n\u00e1stroj d\u016fv\u011bry. Vyjas\u0148uje o\u010dek\u00e1v\u00e1n\u00ed, sni\u017euje prostor pro improvizaci a pom\u00e1h\u00e1 firm\u011b l\u00e9pe \u0159\u00eddit riziko.<\/p>\n\n
