Abstract. Virtualisation is playing a fundamental role in the evolution of
telecommunication services and infrastructures, bringing to rethink some of the
traditional design paradigms of the mobile network and enabling those func-
tionalities necessary for supporting new complex ecosystems where multiple
actors can participate in a dynamic and secure environment. In Small Cell enabled
Mobile Edge Computing deployments, the impact of virtualization technologies is
significant in two main aspects: the design and deployment of the telecommuni-
cation infrastructure, and the delivery of edge services. Besides, the adoption of
virtualization technologies has implications also in the implementation of Self
Organizing Network (SON) services and in the enforcement of Service Level
Agreement (SLA) policies, both critical in the automation of the delivery of
multi-tenant oriented services in such complex infrastructure. From the work
performed by the H2020 SESAME project, the beneficial use of virtualization
techniques emerges in adding network intelligence and services in the network
edge. SESAME relays on virtualization for providing Small Cell as a Service
(SCaaS) and per operator Edge Computing services, consolidating the emerging
multi-tenancy driven design paradigms in communication infrastructures.

1 Introduction
Virtualization technologies decouple software from physical infrastructure, and create
virtual resources dedicated to distinct services. This approach fosters an ef ficient,
flexible and dynamically re-configurable usage of the physical resources, and a rapid
and ef ficient service creation process.
While virtualization is a fundamental element of Cloud Computing, it is also
making its way in the Telecommunication domain. Through virtualization, network
elements, functions and components are released from the limitations of dedicated
hardware and physical constraints, allowing the dynamic set up and reconfiguration of
services and service providers, and the support the functionalities necessary for
implementing multi-tenancy and autonomic management.
