Public cloud storage enables organization and individuals to edit, manage and store data. The storage survives on the remote cloud server, and the same has been accessible on internet under utility billing technique based on the subscription where users just pay for used storage capacity.
It is offered by cloud storage service providers that manages, sources and hosts the storage infra publicly to different users. It is also referred to as utility storage, online storage, and storage as a service.
Generally, public cloud storage enables huge storage space' sourcing on-request on the internet. It is created on the storage virtualization that rationally distributes the large storage in a multi-tenant architecture which is shared among several applications and users.
The capacity of public cloud storage is made probable via two sourcing models -
-- Thin client apps
-- Web services APIs
It enabled via APIs which is designed in order to be utilized for online applications which need access for scalable storage, whereas the thin client apps offer end users a backup and store the local data on the remote cloud storage. Windows Azure, Mezeo, and Amazon S3 are a few famous instances of public cloud storage.
On the contrary to private cloud storage, public cloud storage could save the business from heavy costs of managing, maintaining and purchasing application infrastructure and on-premises hardware. Public cloud service provider is responsible for maintenance and management of system. These cloud storage could be positioned faster as compared to the on-premises infra with infinite scalable platform.
Every individual of an enterprise can utilize the same app through any branch or office utilizing the device which has an access to internet. Security is the major concern which is raised on the public cloud environment; however, when correctly implemented, public cloud could be much secured similar to efficiently managed private cloud environment when the cloud service provider makes use of proper security measures like prevention systems (IDPS) and intrusion detection.
