The hyper competitiveness of medium-size enterprise is not only heavily dependent on its cloud computing infrastructure evolution but also on its adaptation for sustainability to global web interconnection ecosystems. While the bigger multinationals have experienced positive business values due to their economies of scale, the medium-size manufacturing plant still faces greater challenges. We update the view on two similar but evolved theoretical perspectives from Harvard University: Commodity of IT infrastructure and Disruptive Technology into a catalyst model for optimum technology maximisation. This paper proposes the establishment of a new dynamic barebones yet optimised internet infrastructure that will integrate the existing client server into the extranet to form an extended cloud environment. The study's three-stage primary data collection procedure consistently validated our findings. Our results suggest that enterprise should continue to invest in optimised IT infrastructure despite the economic turbulence for competitive gearing in the future.
