k8s, openstack, various services (eg. storage, caching proxy) and overlay network (any supported OSI layer)
Hardware underlying infrastructure => physical devices, networking (L1 and up)
NF Use Cases => Sets of Network Service Chains running on a Telecom workload platform with specific configuration for the platform and the Service Chains
Network Service Chain => Combination of a set of Software Network Functions to provide a higher-level/full service
Software Network Functions => applications which provide network specific services which can be implemented on a host, vm or as a micro service
Examples are broken up based on the layers in an environment running a use case
Examples should be aim to be composable with other examples (especially between layers)
