Ericsson Elevates Cloud-Native Core Network Operations with GitOps

Ericsson has announced a significant enhancement to its core network software deployment strategy, embracing GitOps-compliant packages and configuration management for its cloud-native dual-mode 5G Core network functions (CNFs). This new deployment model is slated for gradual rollout across Ericsson's entire core network portfolio. The telecommunications giant is transitioning from traditional procedure-driven lifecycle and configuration management to declarative, automated workflows, aiming to strengthen cloud-native core operations. This development is highly significant for practitioners, particularly those in the telecommunications sector and anyone managing complex cloud-native infrastructure. It validates GitOps as a robust methodology for even the most demanding, high-stakes environments. For network engineers and DevOps teams, it means a move away from error-prone manual processes towards a system where network configurations are version-controlled, auditable, and automatically reconciled. The benefits include reduced upgrade times, faster service setup, and the ability to implement changes during normal working hours rather than relying on disruptive maintenance windows. This shift is indicative of GitOps' growing acceptance as a standard operating model, extending its reach beyond general Kubernetes deployments into specialized domains like 5G core networks. The move by Ericsson aligns with the broader, well-established trend of GitOps adoption across the cloud-native landscape. GitOps, which uses Git as the single source of truth for infrastructure and application state, has been steadily gaining traction due to its principles of declarative configuration, version control, automated pull-based deployments, and continuous reconciliation. The industry has seen a significant increase in enterprises adopting GitOps as their primary delivery mechanism, with a focus on improving reliability and rollback velocity. Tools like Argo CD and Flux, which implement this pull-based reconciliation model, have matured significantly and are widely used in production environments. Ericsson's integration of GitOps into its 5G core network is a powerful example of this trend, demonstrating how these principles can be applied to achieve greater automation and control in critical infrastructure. In practice, this means that telecommunications operators and other organizations with similar complex, high-availability requirements should closely observe Ericsson's implementation. Key implications include the need for network engineers to become proficient in Git-based workflows and declarative configuration languages. Organizations should also evaluate their existing CI/CD pipelines to ensure they can seamlessly integrate with GitOps principles, particularly for in-service software upgrades (ISSU). Furthermore, the emphasis on auditability and automated reconciliation will necessitate robust monitoring and observability solutions to track the state of the network and quickly identify any deviations from the declared state. Practitioners should consider how this model can be adapted to their own infrastructure, focusing on establishing clear processes, trained teams, and secure repositories to maximize the benefits of GitOps in their specific contexts.
