This is a cloud-based resources are to be managed via a particular strength when administrative tasks are single interface. Services in the public cloud are to be delegated to standard users in specialist inherently designed for management via web APIs. departments. One argument against browser consoles for a For such scenarios, it should be possible to reduce the long time was the poor usability of web interfaces. web interface to the required functions.
