Network Function Virtualization (NFV) and Edge Computing (EC) can accommodate various services on a shared virtualized infrastructure. By using distributed resources available at the network edge, the EC paradigm contributes to share service provisioning. To improve agility and flexibility for service provisioning while reducing deployment costs for infrastructure providers, NFV virtualizes computing, network, and storage resources to decouple network functions from the underlying hardware. Therefore, typical network functions in a virtualized network environment are implemented as software entities called Virtual Network Functions (VNFs), which can run on Virtual Machines (VMs) or containers within off-the-shelf servers. The integration of EC and NFV allows the creation of VNF chains, known as Service Function Chains (SFC), representing end-to-end services and their deployment on edge servers. Edge …
