Abstract: Systems, methods, apparatuses, and computer program products for multi-tiered virtualized network function (VNF) scaling are provided. One method includes detecting a need to scale at least one virtualized network function component (VNFC) implemented as a container, monitoring resource utilization by containers and determining remaining capacity within a current virtual machine hosting the containers, and deciding an allocation of the container to a virtual machine based at least on the resource utilization and the remaining capacity. When it is determined that the remaining capacity is low, the method may further include vertical scaling of the current virtual machine by allocating additional virtualized resources to the current virtual machine, and/or horizontal scaling of the current virtual machine by instantiating a new virtual machine and deploying the container to the newly instantiated virtual machine.
