Information Logistics in Fog Computing environments

The research concerns how to improve data management in Fog environments where both Cloud and Edge resources are involved. This research wants to extend typical patterns which usually implies data movement from the Edge (where data are produced) to the Cloud (where data are processed), to a scenario in which both data and task movement is allowed from the Edge to the Cloud and the vice-versa to improve the efficiency and the effectiveness of data-intensive applications.
This implies the definition of data movement strategies to decide where, when, and how to store data — on the Cloud or on the Edge of the network — and where, when, and how to execute the tasks composing the application, to create a synergy between traditional and cloud approaches able to find a good balance between reliability, security, sustainability, and cost.

IoT-based multi-party business process design and monitoring

Business Processes are more and more exploiting Smart Objects to perform their tasks. This research envisions the adoption of Smart Objects to design reliable business processes and to assess their correct execution. Instead of using control-flow based languages to express the processes, declarative-based approaches like GSM (Guard Stage Milestone) and CMMN (Case Management Modeling Notation) are used.

Adaptive Service Oriented Architectures

Service-based applications (SBAs) are built upon  architectures where distributed capabilities may be under the control of different ownership domains, i.e., the Service Oriented Architectures (SOA). This research aims to support the design and execution of SBAs able to react in case of unavailability (e.g., due to a failure of the computing nodes or the network).  Enhanced Service Registry (URBE, Uddi Registry By Example) and  model for expressing quality of service properties in multi-channel systems have been proposed. More recently, an approach to improve the monitorability of multi-cloud SBAs has been proposed.

Sustainable Information Systems

To reduce the energy consumed during the execution cloud-based applications, proper application design methods and a support during the execution are required. To deal with this issue, the research proposes methods that, while enacting the right adaptation strategy for a given context, allow the improvement of the trade off between QoS and CO2 emission reduction for cloud-based applications.
