Cloud computing este una dintre tendin\u021bele majore care determin\u0103 inovarea IT a unei companii, deoarece permite evitarea achizi\u021bion\u0103rii de solu\u021bii software \u0219i hardware mai complexe, cu economii financiare evidente. Termenul \u201ecloud\u201d se refer\u0103 la o serie de servicii sau software oferite de un furnizor la cererea unui client final, prin internet.<\/p>\n\n\n\n

Prin urmare, sistemul de cloud computing include 3 factori:<\/p>\n\n\n\n

\u2013 furnizor de servicii (cloud provider): se ocup\u0103 cu furnizarea diverselor tipuri de servicii (servere virtuale, stocare, aplica\u021bii complete) conform modelului \u201epay-per-use\u201d;<\/p>\n\n\n\n

\u2013 client administrator: alege \u0219i configureaz\u0103 serviciile oferite de furnizor, oferind, \u00een acela\u0219i timp, o valoare ad\u0103ugat\u0103 precum aplica\u021biile software;<\/p>\n\n\n\n

\u2013 client final: reprezint\u0103 utilizatorul real al acestor servicii.<\/p>\n\n\n\n

\u00cen unele cazuri, clientul administrator \u0219i clientul final pot coincide. De exemplu, un client poate utiliza un serviciu de stocare pentru a face backup-ul propriilor date; \u00een acest caz clientul final va configura \u0219i utiliza serviciul.<\/p>\n\n\n\n

Este important s\u0103 ne amintim c\u0103 multe companii \u00eencearc\u0103 s\u0103 prezinte ca fiind in \u201ecloud\u201d orice software furnizat ca serviciu (Software as a Service) \u0219i orice serviciu de infrastructur\u0103, chiar \u0219i atunci c\u00e2nd unele caracteristici \u0219i func\u021bionalit\u0103\u021bi importante lipsesc.<\/p>\n\n\n\n

Deci, care este \u201eadev\u0103ratul\u201d Cloud Computing?<\/strong><\/p>\n\n\n\n

Care ar trebui s\u0103 fie caracteristicile \u0219i func\u021bionalit\u0103\u021bile unui serviciu \u201ereal\u201d \u00een modalitatea Cloud Computing? Conform American NIST (National Institute of Standards and Technology), cloud computing-ul este un model care permite accesul on-demand, din orice punct la un pool de resurse partajate, care poate fi pus la dispozi\u021bie rapid, cu efort minim de gestionare din partea furnizorului de servicii.<\/p>\n\n\n\n

Caracteristicile \u0219i avantajele Cloud Computing<\/strong><\/p>\n\n\n\n

Datorit\u0103 Cloud Computing se poate evita achizi\u021bionarea de software, hardware, sisteme de re\u021bele \u0219i clustere de solu\u021bii IT simple sau complexe:<\/p>\n\n\n\n

\u2013 investi\u021bii ini\u021biale minime \u0219i posibilitatea de a utiliza modalitatea pay-per-use;<\/p>\n\n\n\n

\u2013 autonomie major\u0103, interfa\u021b\u0103 user friendly, pornire rapid\u0103;<\/p>\n\n\n\n

\u2013 fiabilitatea \u0219i continuitatea serviciului \u00een sine, av\u00e2nd \u00een vedere c\u0103 furnizorul, av\u00e2nd ca activitate principal\u0103 calitatea serviciului de cloud oferit, va avea tot interesul s\u0103 garanteze un nivel \u00eenalt al serviciilor.<\/p>\n\n\n\n

\u2013 Self service On Demand: utilizatorul serviciului trebuie s\u0103 aib\u0103 posibilitatea de a modifica sau elimina diverse abilit\u0103\u021bi, f\u0103r\u0103 interven\u021bia furnizorului de servicii.<\/p>\n\n\n\n

\u2013 Acces distribuit: func\u021bionalit\u0103\u021bile sunt accesibile \u00een orice moment \u0219i loc, dac\u0103 exist\u0103 acces la re\u021bea.<\/p>\n\n\n\n

\u2013 Resource pooling: resursele de calcul ale furnizorului sunt partajate \u0219i servesc mai mul\u021bi clien\u021bi, folosind un model multi-tenant.<\/p>\n\n\n\n

\u2013 Scalabilitate rapid\u0103 \u0219i flexibil\u0103: capacit\u0103\u021bile pot fi puse la dispozi\u021bie \u00een func\u021bie de cererile momentului.<\/p>\n\n\n\n

\u2013 Pre\u021b variabil \u0219i full inclusive: sistemele Cloud trebuie s\u0103 poat\u0103 controla \u0219i optimiza automat utilizarea resurselor \u0219i s\u0103 poat\u0103 genera rapoarte transparente privind utilizarea efectiv\u0103.<\/p>\n\n\n\n
