Broad community entry
Capabilities can be found over the community and accessed via customary mechanisms that promote use by heterogeneous skinny or thick shopper platforms (e.g., cell phones, tablets, laptops, and workstations).

Capabilities might be elastically provisioned and launched, in some instances routinely, to scale quickly outward and inward commensurate with demand. To the buyer, the capabilities obtainable for provisioning typically seem limitless and might be appropriated in any amount at any time.
Measured service
Cloud techniques routinely management and optimize useful resource use by leveraging a metering functionality at some stage of abstraction acceptable to the kind of service (e.g., storage, processing, bandwidth, and energetic consumer accounts). Useful resource utilization might be monitored, managed, and reported, offering transparency for each the supplier and shopper of the utilized service.

Azure integrates the cloud providers that it is advisable to create, check, ship, and take care of your functions, all whereas benefiting from the efficiencies of cloud computing.
Abstract
That is the fundamental idea of cloud computing that helps you understand about cloud providers. All described phrases are sometimes requested by an interviewer. I hope you perceive. Stick with us to study extra about Azure providers. Thanks.
