*2.3.1 Public cloud*

A public cloud is a cloud infrastructure deployed by a provider to offer cloud services to the general public and/or organizations over the Internet. In the public cloud model, there may be multiple tenants (consumers) who share common cloud resources. A provider typically has default service levels for all consumers of the public cloud. The provider may migrate a consumer's workload at any time and to any location. Some providers may optionally provide features that enable a consumer to configure their account with specific location restrictions. Public cloud services may be free, subscription-based or provided on a pay-per-use model. **Figure 1** below illustrates a generic public cloud that is available to enterprises and to individuals.
