Consider a system that could function as a Cloud solution

Consider a system that could function as a Cloud solution. In order for that system to work as needed, several functional and nonfunctional requirements will be required.  Detail at least 3 functional requirements and three nonfunctional requirements required for the Cloud solution. Describe what they will do and why are they essential to the system? Make sure those requirements take into consideration resource requirements, network requirements, and security requirements (attacks, mitigations, vulnerabilities).
