These advancements are pivotal for\u0000integrating intelligent, data-driven applications aimed at enhancing network\u0000reliability and operational autonomy through the introduction of cognition\u0000capabilities, exemplified by the set of enhancements proposed by the emerging\u0000Open radio access network (O-RAN) standards. Despite its potential, the nascent\u0000nature of O-RAN technology presents challenges, primarily due to the absence of\u0000mature operational standards. This complicates the management of data and\u0000applications, particularly in integrating with traditional network management\u0000and operational support systems.

Addressing the skills\u0000gap in telecom business-oriented engineering is crucial for the effective\u0000deployment of O-RAN and the development of robust data-driven applications. To\u0000address these challenges, Boldyn Networks, a global Neutral Host provider, has\u0000implemented a novel cloud-native data analytics platform.
