Service Lifecycle Management in the Cloud Continuum

Résumé

Service computing (alternatively termed service-oriented computing) refers to the cross-discipline that covers the science and technology that bind IT services to business services. Service computing helps in the modeling and the support of complex processes while combining business goals and technical concerns. Specifically, it focuses on the co-creation of value between service consumers and service providers in the context of the several steps (e.g., design, implementation, execution) that make up the lifecycle of the service. The underlying key enabling technologies of service computing involve Service-Oriented Architecture (SOA), cloud computing, social computing, business process management and Web services. Emerging service-based applications in such environments are distributed, modular, reusable through composition techniques (e.g., service orchestration, service choreography) and might adopt novel design patterns that are even more distributed (e.g., micro servi! ces, Function-as-a-Service). From one side, the emerging applications’ services are getting more and more heterogeneous, distributed and mobile. They impose strong requirements and strict Quality of Service (QoS) management on the hosting service providers. Platoons of connected automated vehicles, adaptive streaming and augmented/virtual reality are among the examples of emerging applications. On the other side, with the rise of the cloud continuum, the target runtime environments for these applications are getting more and more distributed, heterogeneous, dynamic and mobile. The cloud continuum encompasses a range of resources and capabilities from public to edge and everything in between, all seamlessly integrated by the so-called next-generation networks (e.g., the fifth-generation/sixth-generation (5G/6G) wireless telco network, content delivery networks (CDN) and information-centric networks). This research work focus on re-considering the service lifecycle management process to support the provisioning of novel and emerging applications in the cloud continuum and its inherent next-generation networks and infrastructures. It proposes several research contributions that cover and support every single step of the process. For practical reasons and for the sake of efficiency, the target contributions mostly focus on NFV domain and consider the Virtualized Network Functions (VNF) as the service building block of the cloud continuum. The contributions range from design (i.e., architectures, specification, prototypes) to models (i.e., semantic-based models, optimization models) and procedures (i.e., description, automation, (re)configuration). The research results were reported in several highly-ranked forums in the networking and service computing research fields.
