Table 10 Overview of research gaps and opportunities identified
Research topic | Research gaps and opportunities |
|---|---|
Multi-cloud concept [RQ1, RQ2] | • Cloud continuum characterization and understanding • Incorporation of new paradigms to the multi-cloud concept: fog computing, osmotic computing |
Multi-cloud by design [RQ3] | • Architectural patterns for multi-cloud native applications • Means and methods to model at high level of abstractions (platform/technology independent) heterogeneous infrastructural elements and application components. • Linking the applications models to the infrastructural models through NFRs characterization especially network, communications, security (i.e. especially data sharing) or even legal |
DevOps for multi-cloud [RQ4] | • Lightweight benchmarking and multi-objective optimization for the selection of the best combination of infrastructural elements. • Federation models for the cloud continuum, including IoT and networks elements to the traditional cloud services. • Application self-healing and migration at run time, with special focus on data portability and stateful components |
Multi-cloud security [RQ5] | • Standard security models or SLAs to evaluate security • Conflicting security policies • Frameworks to provide, assess and monitor security with a quantitative approach • Trustable cloud services • Cloud security posture management |
Multi-cloud certification | • Compositional cloud certification and combination with IoT and 5G certification |
