Description

Cloud computing forms a foundational part of modern digital infrastructure, bringing with it both immense opportunities and complex challenges across various domains. A primary concern consistently addressed in the literature is cloud security, with comprehensive reviews breaking down the extensive security challenges, current threats, and proposed solutions. These discussions cover everything from preventing significant data breaches to navigating complex compliance issues, providing a robust understanding of cloud security fundamentals [1]. Further surveys offer a broad perspective on protecting cloud environments, detailing major security challenges and the diverse solutions being developed to counter different types of attacks and vulnerabilities [7]. In a forward-looking approach, the integration of Blockchain technology is actively explored to enhance cloud computing environments, specifically by improving overall security, transparency, and data integrity across various cloud services [4]. This includes systematic reviews of existing Blockchain-based solutions, which identify their strengths and weaknesses in ensuring secure data sharing, maintaining integrity, confidentiality, and access control within the cloud [10].

Another significant and increasingly critical area of focus is making cloud computing operations more energy-efficient and environmentally sustainable. Research systematically reviews the challenges of power consumption, exploring diverse solutions ranging from sophisticated resource management techniques to intelligent virtual machine scheduling. This work often points out crucial future research directions aimed at fostering a greener cloud infrastructure [2]. Directly related, the concept of green cloud computing is extensively examined, with an emphasis on minimizing energy consumption and reducing carbon footprints in expansive cloud data centers. These reviews detail strategies for sustainable operation and highlight the broader environmental impact of cloud services, advocating for greater sustainability in cloud environments [5].

The evolution of cloud computing also involves its strategic integration with other distributed computing paradigms. For instance, the integration of Edge Computing with cloud computing is a burgeoning field, where existing approaches are categorized, and key challenges like latency and resource constraints are meticulously highlighted. Such analyses indicate where more focused research is needed to make these combined systems truly effective and responsive [3]. Similarly, systematic reviews investigate how Fog Computing is effectively utilized alongside cloud computing. They examine various architectural models, practical applications, and the performance benefits that arise from combining these two paradigms, ultimately addressing how they can collaborate to significantly improve distributed systems [8].

Beyond its foundational technological aspects, cloud computing has transformative applications in specialized sectors. Its integral role in healthcare is widely discussed, looking at how cloud technology can profoundly improve data management, accessibility, and collaborative efforts within medical settings. Importantly, these discussions concurrently address critical concerns such as stringent patient data privacy requirements and complex regulatory compliance unique to the healthcare industry [6]. Complementing these specialized applications, the overarching topic of resource management remains pivotal for optimizing cloud computing operations. Comprehensive surveys delve into various techniques for efficiently allocating and managing vital resources like CPU, memory, and storage, all with the aim of ensuring maximal efficiency, superior performance, and significant cost-effectiveness across diverse cloud environments [9].

Conclusion

This data provides a comprehensive overview of current research trends in cloud computing, highlighting critical areas of development and concern. A major focus is cloud security, with papers detailing diverse threats from data breaches to compliance issues, and exploring solutions including the use of Blockchain technology to enhance data integrity and access control. Alongside security, energy efficiency and green cloud computing are emphasized, with reviews addressing power consumption challenges, sustainable operation strategies, and carbon footprint reduction in data centers. The integration of cloud computing with other distributed paradigms like Edge Computing and Fog Computing is also a significant theme. Research explores architectural models, applications, and challenges such as latency, aiming to create more effective combined systems. Furthermore, the dataset covers specialized applications, such as cloud computing's role in healthcare for improved data management and collaboration, while rigorously addressing patient data privacy and regulatory compliance. Effective resource management is also central to cloud operations, with surveys detailing techniques for optimizing CPU, memory, and storage allocation for efficiency and cost-effectiveness. Overall, the collection reflects a dynamic research landscape focused on enhancing security, sustainability, integration, and performance across various cloud computing applications.
