Several vendors are progressing their NFV strategies and pursuing the end game of every telco virtualization strategy, where virtualized network functions are deployed in a cloud-native environment. This brings considerable benefits, including portability, resource availability, and being able to adapt to network and traffic demands in near-real time. Several vendors are now pursuing cloud-native strategies while telcos are now issuing request for proposals (RFPs) that have a strong requirement for cloud-native capabilities. For example, Nokia recently won a contract with 3UK for a cloud-native packet core, and Oracle has repositioned its telco strategy toward providing cloud-native capabilities for several different parts of the telco cloud stack. The cloud-native capability may be the foundation for even more advanced features, including hybrid clouds, service sandboxes in public clouds, and more flexible networks toward 5G.
