Green Cloud Computing: Goals, Techniques, Architectures, and Research Challenges

Customers from all around the world may access processing power and resources through cloud computing. It offers excellent performance and cost savings compared to specialized high-performance computing equipment. However, this service necessitates enormous data centers, which use a lot of energy and generate a lot of CO2. Green cloud computing is created to solve this problem by using recycled energy to cut down on energy use and CO2 emissions. The motivation behind choosing Green Cloud is committed to developing environmentally sound, resource-efficient, low-carbonemitting, and recyclable solutions. Green computing research focuses on creating effective clouds with environmentally friendly features including power management, virtualization, high-performance computing, load balancing, green data centers, reusability, and recyclability. Providing Quality Of Service to end users while also achieving green computing for computing systems, attaining energy-efficiency control, and meeting a performance guarantee have all become essential concerns for cloud providers. In this paper, the different architectures of green cloud computing are surveyed. The methodology includes the identification of techniques to make the cloud ‘green’. Further, the goals and research challenges of green cloud computing are explored. This research provides a state-of-art about the green cloud for the researchers.
