Model nasadenia<\/h2>\n\n\n\n

Z poh\u013eadu sp\u00f4sobu, ak\u00fdm je cloud poskytovan\u00fd, pozn\u00e1me viacero modelov nasadenia.<\/p>\n\n\n\n

– Verejn\u00fd cloud (public cloud)<\/strong> \u2013 ide o model, kedy je slu\u017eba poskytovan\u00e1 \u0161irokej verejnosti a m\u00f4\u017ee si ju zriadi\u0165 takpovediac ka\u017ed\u00fd. Tak\u00e1to slu\u017eba je pre v\u0161etk\u00fdch jej pou\u017e\u00edvate\u013eov rovnak\u00e1 a s rovnakou funkcionalitou. Ide o \u201etradi\u010dn\u00fd\u201c alebo \u201eklasick\u00fd\u201c model cloud rie\u0161enia. Prakticky si pod t\u00fdm m\u00f4\u017eeme predstavi\u0165 napr\u00edklad vyh\u013ead\u00e1vanie od Google alebo VPS od Websupportu<\/a>.<\/p>\n\n\n\n

– Priv\u00e1tny cloud (private cloud)<\/strong> \u2013 pri tomto modeli cloudu je rie\u0161enie vyhraden\u00e9 len pre jednu organiz\u00e1ciu, napr\u00edklad firmu. Priv\u00e1tny cloud m\u00f4\u017ee, ale aj nemus\u00ed by\u0165 v administr\u00e1cii tejto organiz\u00e1cie. Tak isto m\u00f4\u017ee, ale aj nemus\u00ed by\u0165 umiestnen\u00fd v priestoroch organiz\u00e1cie. Typick\u00fdm pr\u00edkladom je, ke\u010f poskytovate\u013e verejn\u00e9ho cloudu vyhrad\u00ed v\u00fdpo\u010dtov\u00fd v\u00fdkon a \u010fal\u0161ie slu\u017eby len pre jednu organiz\u00e1ciu.<\/p>\n\n\n\n

– Hybridn\u00fd cloud (hybrid cloud)<\/strong> \u2013 model hybridn\u00e9ho cloudu je kombin\u00e1ciou verejn\u00e9ho a priv\u00e1tneho cloudu. Navonok tak\u00e9to rie\u0161enie vystupuje ako jedno rie\u0161enie. Pr\u00edkladom m\u00f4\u017ee by\u0165 webov\u00e1 prezent\u00e1cia vo verejnom cloude, ktor\u00e1 je prepojen\u00e1 na priv\u00e1tny cloud s inform\u00e1ciami o z\u00e1kazn\u00edkoch a ich transakci\u00e1ch.<\/p>\n\n\n\n

S ob\u013e\u00fabenos\u0165ou cloudov\u00fdch rie\u0161en\u00ed pri\u0161la aj potreba tzv. multicloudu<\/strong> (multi-cloud<\/em> alebo multi cloud<\/em>). Multicloud je pou\u017eitie viacer\u00fdch poskytovate\u013eov cloudu. V porovnan\u00ed s hybridn\u00fdm cloudom, ktor\u00fd sk\u00f4r rie\u0161i architekt\u00faru rie\u0161enia, sa multicloud zameriava na zn\u00ed\u017eenie z\u00e1vislosti od jedn\u00e9ho poskytovate\u013ea<\/strong>. D\u00f4vodov m\u00f4\u017ee by\u0165 ale viacero, napr\u00edklad dodr\u017eiavanie pravidiel ukladania osobn\u00fdch inform\u00e1ci\u00ed, geografick\u00e9ho umiestnenia slu\u017eieb, zn\u00ed\u017eenie latencie, optimaliz\u00e1cia n\u00e1kladov a pod. <\/p>\n\n\n\n

Distribu\u010dn\u00fd model<\/h2>\n\n\n\n

To, ak\u00fdm sp\u00f4sobom je cloud rie\u0161enie pon\u00fakan\u00e9, resp. ako ve\u013emi ide do h\u013abky, upres\u0148uje jeho distribu\u010dn\u00fd model.<\/p>\n\n\n\n

– Infra\u0161trukt\u00fara ako slu\u017eba – IaaS (Infrastructure as a Service)<\/strong> \u2013 naj\u010dastej\u0161ie ide o prev\u00e1dzkovanie virtualizovanej infra\u0161trukt\u00fary, kedy sa o v\u0161etky probl\u00e9my s hardv\u00e9rom star\u00e1 poskytovate\u013e. Okrem virtu\u00e1lnych strojov (VM) m\u00f4\u017eu by\u0165 s\u00fa\u010das\u0165ou \u00falo\u017eisk\u00e1 pre d\u00e1ta, siete, load-balancer a pod. Ide o vhodn\u00e9 rie\u0161enie<\/a>, ke\u010f chcete ma\u0165 kontrolu nad v\u0161etk\u00fdm od opera\u010dn\u00e9ho syst\u00e9mu. <\/p>\n\n\n\n

– Platforma ako slu\u017eby – PaaS (Platform as a Service)<\/strong> \u2013 ide o ob\u013e\u00faben\u00fd distribu\u010dn\u00fd model najm\u00e4 z poh\u013eadu developerov, kedy im poskytovate\u013e zabezpe\u010duje cel\u00e9 behov\u00e9 prostredie pre r\u00f4zne programovacie jazyky, datab\u00e1zy, API a podobne, vr\u00e1tane jeho aktualiz\u00e1ci\u00ed. V\u00fdvoj\u00e1r sa tak m\u00f4\u017ee zamera\u0165 len na tvorbu k\u00f3du a nemus\u00ed rie\u0161i\u0165 prostriedky na jeho prev\u00e1dzku. <\/p>\n\n\n\n

– Softv\u00e9r ako slu\u017eba – SaaS (Software as a Service)<\/strong> \u2013 \u201enajvy\u0161\u0161\u00ed\u201c distribu\u010dn\u00fd model, kedy si pou\u017e\u00edvate\u013e kupuje pr\u00edstup k aplik\u00e1cii a nie samotn\u00fa aplik\u00e1ciu. A u\u017e v\u00f4bec ho nezauj\u00edma, kde a ako je aplik\u00e1cia prev\u00e1dzkovan\u00e1. Pr\u00edkladom m\u00f4\u017eu by\u0165 online kancel\u00e1rske n\u00e1stroje, CRM, r\u00f4zne \u00falo\u017eisk\u00e1 typu Dropbox, komunika\u010dn\u00e9 n\u00e1stroje ako Zoom alebo Skype a pod.<\/p>\n\n\n\n

Okrem t\u00fdchto distribu\u010dn\u00fdch modelov sa ob\u010das vyskytn\u00fa tak\u00e9, ktor\u00e9 poskytuj\u00fa nie\u010do-ako-slu\u017ebu<\/strong>. Typicky to b\u00fdvaj\u00fa datab\u00e1zy, v poslednej dobe kontajnery alebo serverless slu\u017eby s pr\u00edstupom funkcia ako slu\u017eba. \u010castokr\u00e1t sa radia do kateg\u00f3rie \u010coko\u013evek ako slu\u017eba<\/em> – XaaS (Anything as a Service), \u010do je ozna\u010denie mno\u017estva produktov a n\u00e1strojov, ktor\u00e9 je mo\u017en\u00e9 zak\u00fapi\u0165 pomocou \u201eako slu\u017eby\u201c.<\/p>\n\n\n\n

V\u00fdhody cloudu<\/h2>\n\n\n\n

– pr\u00edstup odkia\u013eko\u013evek,<\/p>\n\n\n\n

– absencia potreby n\u00e1kupu vlastn\u00e9ho hardv\u00e9ru,<\/p>\n\n\n\n

– r\u00fdchle nav\u00fd\u0161enie v\u00fdkonu a mo\u017enosti \u0161k\u00e1lovania,<\/p>\n\n\n\n

– optimaliz\u00e1cia prev\u00e1dzkov\u00fdch n\u00e1kladov,<\/p>\n\n\n\n

– lep\u0161ie zabezpe\u010denie a dodr\u017eiavanie bezpe\u010dnostn\u00fdch \u0161tandardov ako pri on-premise rie\u0161eniach.<\/p>\n\n\n\n

Nev\u00fdhody<\/h2>\n\n\n\n

– nevyhnutnos\u0165 internetov\u00e9ho pripojenia,<\/p>\n\n\n\n

– komplexita multicloudu – je l\u00e1kav\u00fd, ale \u0165a\u017ek\u00fd,<\/p>\n\n\n\n

– mo\u017enos\u0165 straty s\u00fakromia,<\/p>\n\n\n\n

– z\u00e1vislos\u0165 na poskytovate\u013eovi a konkr\u00e9tnych funkci\u00e1ch.<\/p>\n","protected":false},"excerpt":{"rendered":"
