#### **3.1 Green cloud computing services**

Cloud computing is an on-demand internet computing service that provides shared computer facilities, data storage to computing devices, servers, and computer processing facilities. Cloud computing is based on sharing computing facilities such as servers, computer networks, data storage devices, computing applications, and other services. This service provides access to a shared pool of configurable computing systems such as servers, computers, data storage computing devices, and other services. Cloud computing services can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and organizations with several capabilities to store and process their data in private cloud computing data centers. Cloud computing allows organizations and companies to get faster computing services and minimize high infrastructure costs such as expensive software costs and servers. Cloud computing allows companies to get their applications up and run with better manageability and less computing maintenance costs. Cloud computing information teams can easily adjust computing resources to perform unpredictable computing business tasks. Cloud computing applies high-performance computing power to perform tens of trillions of computations per second. By using cloud computing services, companies and organizations can focus on their core activities instead of spending money, time, and staff on computer facilities.

Cloud computing and storage solutions cut companies' and organizations' energy consumption.
