Cloud computing has revolutionized the deployment of innovative services, with cloud-native applications becoming a fundamental design pattern. Kubernetes has emerged as the leading platform for container and application management in this paradigm. For telecommunication companies (Telcos) with numerous edge sites, adopting cloud-native solutions offers the potential for rapid deployment, configuration, and maintenance of network applications, while ensuring a robust certification process. However, this shift requires a certified, modular, and extensible framework to manage multiple edge sites along with their associated Network Functions and services. The Sylva Project aims to provide such a framework, offering a reference implementation based on open-source software tailored to European Telcos' needs.
