  5G realizes an impactful convergence, where Network Functions Virtualization
(NFV) and cloud-native models become fundamental for profiting from the
unprecedented capacity offered at the 5G Radio Access Network (RAN). For
providing scalability and automation management over resources in 5G
infrastructure, cloud-native and Platform as a service (PaaS) are proposed as
solutions for paving the way for vertical applications in 5G. This paper
leverages cloud-native models, PaaS, and virtual testbed instances to provide
key platform provisioning and service life-cycle management features to a
selected User Generated Content (UGC) scenario in multimedia applications.
Specifically, this article and results show how service-level telemetry from a
UGC cloud-native application is used to automatically scale system resources
across the NFV infrastructure.
