An Extended Framework for Semantic Interoperability in PaaS and IaaS Multi-cloud

Cloud computing is currently a widely used technology, helping enterprises focus on their value-added, rather than spending time and money acquiring and managing software or hardware solutions. Unfortunately, it suffers from the lock-in problem, which leads cloud customers to use specific solutions from a single cloud provider. On the other hand, the multi-cloud strategy is becoming the trend these days, as it remains the best way to maximize the benefits of cloud computing technology. Consequently, communication between solutions of different cloud providers is necessary to ease access and use of services in multi-cloud environments. Hence, even with efforts to standardize semantic interoperability in multi-cloud computing, this problem remains difficult due to the different representation models used by cloud providers. In this paper, we propose an extended version of a framework presented in a previous work dealing with semantic interoperability in a multi-cloud environment. This extended framework is based on five new components, which improves our previous framework and covers, in addition to the IaaS service model, the PaaS one. The main objective is the retrieval of IaaS resources and PaaS services easily. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
