A public cloud environment is the most standard model of cloud computing, and in this kind of an environment, the service provider makes different types of resources like storage and applications, and then make these available to the general public. A public cloud service might be available free of cost, or in a pay-per-usage model. For any small or medium enterprise, public cloud acts as a boon as this enables them to offload their data storage. This frees up the enterprises from the expensive costs of purchasing, managing and maintaining their IT hardware and software.
The main reason why most businesses prefer to opt for a public cloud environment is that it can be deployed faster and it ensures more accessibility and scalability as compared to on premise data storages. Apart from storing the static data, a public cloud storage service can also store the live data that is generated by the applications that run on the on premise resources of a company.
