Il corso è rivolto ad amministratori di sistema, sviluppatori software, data analyst o responsabili di settore aziendali in cui si processano grandi flussi di dati e si vuole dare una comprensione delle problematiche tecniche a cui si deve fare fronte e a cui ElasticSearch dà una risposta.

Per la partecipazione al corso sono richieste competenze in ambito sistemistico generali, molto apprezzate saranno le competenze in ambito Linux.

In alternativa è possibile fruire al meglio del corso se si è dotati di una buona conoscenza delle architetture software, prettamente basate sul modello client/server su reti TCP/IP.
