Detailed explanation-1: -Lock-in means which of the following? Refers to the ability of a customer To increase the computing resources in peak times without having to worry about overloading a system or having to buy additional hardware.
Detailed explanation-2: -Cloud Elasticity: Elasticity refers to the ability of a cloud to automatically expand or compress the infrastructural resources on a sudden up and down in the requirement so that the workload can be managed efficiently.
Detailed explanation-3: -Resource pooling enables scalability for cloud providers and users, letting them add or remove compute, storage, networking and other assets as needed. This helps enterprise IT teams optimize their cloud-hosted workloads and avoid end-user bottlenecks.
Detailed explanation-4: -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-5: -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.
