This paper describes the design and implementation of an on-premise Kubernetes Cluster infrastructure at the National Institute of Geophysics and Volcanology (INGV) in Rome. The project was born from the need to modernize the existing infrastructure, based on a monolithic WebFarm, which showed increasing limitations in terms of scalability, security and IT resource management. The previous architecture required continuous manual interventions, was inefficient in managing IP addresses and vulnerable to frequent cyber-attacks. The main objective was to migrate applications and web services to a new cluster architecture that ensures automated management, greater reliability and operational flexibility. The Kubernetes system was chosen for its container orchestration capabilities, improving...
