Dynatrace: osservabilità e sicurezza unificate

event 10/07/2023

face ALESSIO TOZZINI, SIMONE CONTI E MICHELANGELO UBERTI

La settimana scorsa abbiamo tenuto il Red Symposium, l'evento interno di Extra Red in cui da anni ci occupiamo di raccontare a tutti i nostri colleghi, e a volte amici e "vicini", tecnologie e progetti innovativi, per stimolare la curiosità e la disseminazione di conoscenze.
In questa occasione abbiamo avuto come ospiti Michelangelo Uberti, Simone Conti ed Alessio Tozzini di Dynatrace, che sono venuti nella nostra sede a Pontedera per mostrarci nel dettaglio quello che fa la loro piattaforma di osservabilità e come già sapevamo è stato un successo: le presentazioni di Dynatrace hanno un effetto WOW!!! Gigantesco! Grazie ancora a Michelangelo, Simone ed Alessio per la loro disponibilità e competenza. Avremo sicuramente modo di rivederci presto.

Il tema dell'observability è caldo, soprattutto se combinato con i concetti di AI, automation e security e ci teniamo fortemente a proseguire il nostro studio e approfondimento su queste tematiche.

Si è verificato un errore nell'elaborarazione del modello.
