Name	Type	Description
ServiceRegistry	simple module	This module models the functionalities of the Service Registry entity in the MEC architecture (ETSI GS MEC 003). It exposes a REST API compliant with ETSI GS MEC 011, allowing MEC applications to discover MEC services available in the MEC host. In particular, MEC applications can obtain the IP address and port number for each instantiated MEC service, so that they can start sending requests to it
