A fost cea mai complex\u0103 \u0219i detaliat\u0103 sesiune la care am avut ocazia s\u0103 particip. Mesajul general de la Cisco a fost urm\u0103torul: anterior, elementele tradi\u021bionale ale sistemelor IT (re\u021bea, servere, stocare etc.) erau conectate \u0219i configurate separat. Sarcina inginerilor a fost s\u0103 aduc\u0103 totul \u00eentr-un mediu de lucru gestionabil unic. UCS a schimbat situa\u021bia \u2013 partea de re\u021bea a fost separat\u0103 \u00eentr-un domeniu distinct, iar gestionarea serverelor s-a realizat centralizat dintr-un singur panou. Indiferent de c\u00e2te servere sunt \u2013 10 sau 10 000, orice cantitate este controlat\u0103 dintr-un singur punct de gestionare, printr-un singur cablu av\u00e2nd loc at\u00e2t gestionarea, c\u00e2t \u0219i transmiterea datelor. ACI permite reunirea \u00een aceea\u0219i consol\u0103 de gestionare at\u00e2t a re\u021belei, c\u00e2t \u0219i a serverelor.<\/p>\n<p>A\u0219adar, microsegmentarea re\u021belelor este o func\u021bie esen\u021bial\u0103 a ACI, care permite separarea granular\u0103 a aplica\u021biilor \u00een sistem cu diferite niveluri de interac\u021biune \u00eentre ele \u0219i cu lumea extern\u0103. De exemplu, dou\u0103 ma\u0219ini virtuale gestionate de ACI nu pot comunica \u00eentre ele \u00een mod implicit. Interac\u021biunea dintre ele este deschis\u0103 doar prin activarea a\u0219a-numitului \u201econtract\u201d, care permite detalierea listelor de acces pentru o segmentare detaliat\u0103 (\u00een alte cuvinte \u2013 micro) a re\u021belei. <\/p>\n<p>Microsegmentarea permite ajustarea precis\u0103 a oric\u0103rui segment al sistemelor IT prin alocarea oric\u0103ror componente \u0219i interconectarea acestora \u00een diverse configura\u021bii ale ma\u0219inilor fizice \u0219i virtuale. Se creeaz\u0103 grupuri de elemente de calcul finale (EPG), care aplic\u0103 politici de filtrare \u0219i rutare a traficului. Cisco ACI permite gruparea acestor EPG \u00een aplica\u021bii existente \u00een noi microsegmente (uSeg) \u0219i configurarea politicilor sau atributelor de re\u021bea pentru fiecare element specific al microsegmentului.<\/p>\n<p>De exemplu, pute\u021bi asigna servere web unei anumite EPG pentru a aplica politici uniforme. Implicit, toate nodurile de calcul din EPG pot comunica liber \u00eentre ele. Cu toate acestea, dac\u0103 web-EPG include servere web pentru etapele de dezvoltare \u0219i produc\u021bie, poate avea sens s\u0103 le interzicem complet comunicarea \u00eentre ele pentru a garanta \u00eempotriva defec\u021biunilor. Microsegmentarea cu Cisco ACI permite crearea unei noi EPG \u0219i aplicarea automat\u0103 a politicilor pe baza atributelor numelui VM, cum ar fi \u201eProd-xxxx\u201d sau \u201eDev-xxx\u201d.<\/p>\n<p>Desigur, aceasta a fost una dintre sesiunile cheie ale programului tehnic.<\/p>\n<h2>Evolu\u021bia eficient\u0103 a re\u021belei DC (Evolu\u021bia re\u021belei datacentrelor \u00een contextul tehnologiilor de virtualizare)<\/h2>\n<p><img decoding=\"async\" alt=\"Cisco Live 2019 EMEA.
