A recent study, conducted by the international firm S&P Global Market Intelligence – on behalf of Cloud Oracle Infrastructure (Oci), certified the progressive trend of large enterprises to choose multicloud services over single-source cloud services (https://www.corrierecomunicazioni.it/digital-economy/cloud/sovranita-dei-dati-il-multicloud-la-chiave-per-il-40-delle-big-company/). This trend is mainly driven by the needs of enterprises to (i) maintain the sovereignty of data sent ‘on the clouds’ and (ii) optimise the costs of cloud services, both issues that have been known for some time in the cloud computing environment. Indeed, the risk for companies is to invest in massive acquisition of user data to be stored on one provider’s cloud space and then having to go through complex procedures to migrate user data to another cloud service provider (the so-called ‘lock-in’ effect). In the case of more complex cloud computing services (such as those also providing software services for optimising work within the company based on the management of acquired data), the increase in IT security and cost effectiveness in current Multiclould contracts compared to previous ‘single-source’ cloud computing contracts have increased the use of the Multicloud formula.
