Sylva, a Linux Foundation Europe project backed by major telecom operators, provides a standardized declarative cloud-native framework for building telco infrastructures. Canonical Kubernetes integrates with Sylva to deliver vendor-neutral, open infrastructure for telco clouds. Key benefits include native support for 5G-required features like SR-IOV, DPDK, and PTP synchronization without proprietary operators, clean GitOps pipeline compatibility via Cluster API and FluxCD, and up to 15 years of Long Term Support through Ubuntu Pro. The architecture avoids proprietary lock-in by keeping Kubernetes distributions upstream-aligned and modular, allowing telcos to customize and maintain their platforms over long operational lifecycles without forced disruptive migrations.
