“…In all, 24 papers answer none of the two questions, but they are more or less related to SMEs’ adoption of HPC or cloud contract as they addressed the benefits or the challenges of SMEs accessing HPC through the cloud or the challenges associated with cloud contract (Gašperlin et al , 2019; Borštnar et al , 2015; Besednjak Valič et al , 2021; Botelho and O’Gorman, 2021; Overly, 2017). Some of them discussed cloud contracts from a legal perspective such as copyright (Savelyev, 2014), cost sharing or cost deferral (Chen et al , 2019; Goldstein, 2020) or treating cloud contract as a digital asset (Banta, 2014). Some of the papers investigated cloud computing resource provision, such as designing an auto-scaling mechanism to reduce violation and proposing a multiple stage programme to optimize resource allocation (Yadav et al , 2022; Bülbül et al , 2021), while others focused on the technological aspects such as how to design a smart contract using blockchain (Aguilera et al , 2021; Dorsala et al , 2020; Xu et al , 2020) or algorithm issues in the cloud contract (Tiganoaia et al , 2019; Taylor et al , 2018).…”
