How does cloud computing affect resources? - -Cloud computing allows the allocation of resources to be adjusted as needed, creating a hardware-independent framework for future growth and development. What are 5 characteristics of cloud computing, regardless of the forms that they are delivered in? - - 1) Managed by the provider 2) Flexible resource management 3) Network accessible 4) Sustainable 5) Managed through self-service on demand.
