However, cloud computing has become more widely accepted and as a result, has become susceptible to more hacking and different and newer cyberattacks service providers had not accounted for [5]. diffusion of cloud computing. Furthermore, this work proposes to standardize and modularize industrial data infrastructure for smart energy savings. This study is intended to add to the growing body of available business value-focused Cloud Computing research and provides a starting point for further conceptual and empirical work. While cloud services such as webmail, Flickr and YouTube have been widely used by individuals for some time, it not until relatively recently that organisations have began to use cloud services as a tool for meeting their IT needs. Some of the security risks and attacks organizations are faced with are data breaches, malware injection attacks, Denial of Service (DoS) attacks, SQL injection, authentication attack and data losses. 1. The paper starts explaining the benefits of cloud computing and move towards the testing challenges faced by testers. Basically it’s a new concept of providing virtualized resources to the consumers. Current methods and data infrastructures for industrial energy savings were comprehensively reviewed to showcase the potential for a more accurate and effective digital twin-based infrastructure for the industry. Due to a lack of financial resources and expertise, small enterprises tend to find novel ways to utilize IT resources in order to reduce IT adoption costs, to achieve better flexibility, business agility and scalability, and to react faster, Cloud Computing is currently receiving unprecedented levels of attention despite the fact that opinion on the potential for successful Cloud adoption is both conflicting and divided. research, that is collecting data from published journal papers and conference papers. benefits of cloud computing, as well as the ten risks and challenges associated with cloud computing.
