Napriek podivn\u00e9mu pojmenovaniu vytv\u00e1raj\u00fa s\u00fabor slu\u017eieb poskytovate\u013eov cloudu.

Ako bolo uveden\u00e9 v oddiele 2.2, PaaS sa nach\u00e1dza nad IaaS, a v pr\u00edpade GCP ho m\u00f4\u017eeme pova\u017eova\u0165 aj za ponuku nad GKE. GAE je \u0161pecializovan\u00fd Google PaaS a ako sami seba najlep\u0161ie opisuj\u00fa \u2014 \u201edoneste svoj k\u00f3d, my sa postar\u00e1me o v\u0161etko ostatn\u00e9\u201c. <\/p>\n

<\/p>\n

To zaru\u010duje, \u017ee klienti pou\u017e\u00edvaj\u00faci GAE sa nemusia zaobera\u0165 z\u00e1kladn\u00fdm hardv\u00e9rom\/middleware, a m\u00f4\u017eu ma\u0165 u\u017e predkonfigurovan\u00fa platformu pripraven\u00fa na pr\u00e1cu; v\u0161etko, \u010do musia urobi\u0165, je poskytn\u00fa\u0165 k\u00f3d potrebn\u00fd na jeho spustenie. <\/p>\n

<\/p>\n

Pod\u013ea m\u00f4jho n\u00e1zoru je GAE najlep\u0161\u00edm miestom na za\u010diatok, ak ste v\u00fdvoj\u00e1r s v\u00fdborn\u00fdm n\u00e1padom, ale nechcete sa zaobera\u0165 rutinnou pr\u00e1cou pri nastavovan\u00ed serverov, vyva\u017eovan\u00edm z\u00e1\u0165a\u017ee a v\u0161etkou tou \u010fal\u0161ou \u010dasovo n\u00e1ro\u010dnou pr\u00e1cou devops\/SRE.
