Cloud Computing Fundamentals Quiz

Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.

The five essential characteristics are on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

Cloud computing typically uses a pay-as-you-go model.

<p>On-demand self-service = A consumer can provision computing capabilities without requiring human interaction with each service provider Broad network access = Capabilities are available over the network and accessed through standard mechanisms promoting use by different client platforms Resource pooling = Provider's computing resources are pooled to serve multiple consumers using a multi-tenant model Rapid elasticity = Capabilities can be rapidly and elastically provisioned to quickly scale out and rapidly released to quickly scale in</p> Signup and view all the answers
