6.4.4 H2020 5G SONATA project
6.4.4.1 Introduction

SONATA [Ref.6.4.4-1] aims at increasing the flexibility and programmability of 5G networks with a novel
Service Development Kit and a novel modular Service Platform and Service Orchestrator; it will bridge the
gap between telecom business needs and operational management systems. The scope of SONATA is
represented by a new Service Development Kit, the Management System and the Service Platform including:
a customizable Service Orchestrator, a Resource Orchestrator, a Service Information Base along with various
Enablers; we use here the ETSI reference model as a terminological framework. In fact, while ETSI’s division
into Service and Resource orchestrator can be mapped onto SONATA’s service platform, SONATA is much
more flexible in this regard and allows not only replacing these orchestration aspects individually, but even
to change the division of work between these functions if so desired. This is achieved by SONATA’s
microservices-based architecture; e.g., the resource orchestrator corresponds by and large to SONATA’s
default placement plugin.
