Intern experience in Promedius was a happy and precious experience, since it is hard to expreince enterprise-level infrastructure for a person who has no career. Since some of Promedius' products are closed-network on-premise products, Product infrastructure was important as well as corporate internal infrastructure. It was a precious experience to meet both infrastructure at once.- Provided a proof of conecpt level closed-network on-premise license management system- Integrated FreeIPA for internal server user management - Implemented and integrated Prometheus and Grafana for GPU usage monitoring.
