Definition
In cloud computing, elastic pools of virtualized, configurable IT resources are provided as services that can be accessed over a network and used on demand. Providers of resources can achieve higher utilization by allowing multiple tenants to use their resources, thereby achieving provider-side economies of scale. Consumers of resources benefit from a convenient, self-service, on-demand model of allocating and de-allocating...
