Item Reference ITS Architectures in Europe(Wiley-Blackwell, 2015-11-23) Molinete, Begoña; Campos, Sergio; Olabarrieta, Ignacio; Torre, Ana Isabel; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANA; SMART_TRANSPORT; IA; HPAThis chapter outlines the reference architectures conceived for intelligent transportation systems (ITS) planning and deployment in Europe, their evolution through the inputs provided by major ITS projects and initiatives and some experiences from the authors when facing the definition of ITS architectures through their involvement in research projects such as Cybercars-2 and MoveUs, by following different approaches. In view of the project's ambitious goals, the definition of an architecture supporting the cloud platform operation and the delivery of mobility services envisaged, with a predominant role of ITS, entailed a huge effort. The main objective was to define a comprehensive architecture for the MoveUs cloud-based platform, the specifications of its core facilities and the high- level interfaces between the different platform components. The methodology adopted to define the specifications of this platform integrated insights and approaches from different engineering fields: traffic engineering, data analytics, software architecting and cloud-based computation deployment.Item Understanding the challenges and novel architectural models of multi-cloud native applications – a systematic literature review(2023-12) Alonso, Juncal; Orue-Echevarria, Leire; Casola, Valentina; Torre, Ana Isabel; Huarte, Maider; Osaba, Eneko; Lobo, Jesus L.; HPA; Tecnalia Research & Innovation; Quantum; IAThe evolution of Cloud Computing into a service utility, along with the pervasive adoption of the IoT paradigm, has promoted a significant growth in the need of computational and storage services. The traditional use of cloud services, focused on the consumption of one provider, is not valid anymore due to different shortcomings being the risk of vendor lock-in a critical. We are assisting to a change of paradigm, from the usage of a single cloud provider to the combination of multiple cloud service types, affecting the way in which applications are designed, developed, deployed and operated over such heterogeneous ecosystems. The result is an effective heterogeneity of architectures, methods, tools, and frameworks, copying with the multi-cloud application concept. The goal of this study is manifold. Firstly, it aims to characterize the multi-cloud concept from the application development perspective by reviewing existing definitions of multi-cloud native applications in the literature. Secondly, we set up the basis for the architectural characterization of these kind of applications. Finally, we highlight several open research issues drawn up from the analysis carried out. To achieve that, we have conducted a systematic literature review (SLR), where, a large set of primary studies published between 2011 and 2021 have been studied and classified. The in-depth analysis has revealed five main research trends for the improvement of the development and operation DevOps lifecycle of “multi-cloud native applications”. The paper finishes with directions for future work and research challenges to be addressed by the software community.
