Green cloud is a sophisticated packet-level simulator for energy-conscious cloud computing data centers with a focus on cloud communications. It provides detailed fine grain modeling of the energy consumed by the data center computer equipment, such as computer servers, network switches and communication links.
GreenCloud can be used to develop new solutions in monitoring, resource allocation, workload scheduling as well as optimization of communication protocols and network infrastructures. It is published under the General Public License Agreement and is an extension of the well-known NS2 network simulator.
Green computing refers to the environmentally friendly and environmentally responsible use of computers and their associated resources with industry and IT services. In other words, it involves the design, engineering, and use of computing devices in a way that can reduce any adverse impact on the environmental impact on the IT industry. Green means respectful of the environment, while the cloud is the representative of the Internet service delivery model.
Computer makers are investing in technology that can help design energy-efficient computing devices that mitigate the use of hazardous materials and also help maximize the use of energy efficiency while reducing carbon and gas emissions. Green cloud practices also involve minimizing the use of resources such as water used to cool data centers. By adopting the green cloud initiatives, companies can not only contribute their share to the protection of nature, but can also achieve cost savings by maximizing the use of resources.
