Il corso “CXS-320 – XenServer 8 Administration” fornisce le competenze fondamentali per l’installazione, la configurazione e la gestione di ambienti virtualizzati implementati su piattaforma XenServer.
I partecipanti apprenderanno come creare e amministrare macchine virtuali, gestire storage e networking virtuale, garantire la continuità operativa e ottimizzare le prestazioni dell’infrastruttura IT. Durante il corso vengono trattati anche aspetti pratici come il monitoraggio del sistema, backup e ripristino, gestione degli host e sicurezza dell’ambiente virtuale.
