Detailed explanation-1: -The National Institute of Standards Technology (NIST) lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.
Detailed explanation-2: -According to NIST definition of cloud computing, it has five characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service, while mobile computing focuses on device mobility and context awareness considering networking and mobile resource/data access.
Detailed explanation-3: -Broad network access means that the cloud customer or tenant, whoever’s consuming a service, does not manage the IT service infrastructure. And as a result, this means that that IT service runs in a provider data center somewhere and is therefore accessible to the consumer over a network.
