We're talking about cloud computing, which stores programs and information on a "cloud" made up of thousands of connected computers and servers that can all be accessed online. All of our operations are now web-based rather than desktop-based, thanks to cloud computing. Any machine with an Internet connection may access all of our programs and publications. The cloud computing paradigm is evolving to provide end users with trustworthy, personalized, and QoS-ensured dynamic computing environments. In this study, we aimed to investigate a wide new range of cloud computing services, applications and features This study illustrates to organizations and consumers how cloud computing may provide trustworthy, personalized, and cost-effective services for a variety of applications.
