A public cloud is a type of cloud computing model where computing resources, including storage, are owned and operated by third-party cloud service providers and made available to multiple organizations or individuals over the internet. In the context of cloud storage, a public cloud refers to storage infrastructure and services provided by cloud service providers, accessible to the general public or organizations on a subscription basis.

Public cloud storage solutions offer scalability, flexibility, and cost-effectiveness, allowing organizations to store and manage data without the need for extensive on-premises infrastructure. Data stored in public cloud storage is typically hosted in off-site data centers managed by the cloud provider, and accessed via the internet using web-based interfaces or APIs.

Public cloud storage providers offer a range of storage options, including object storage, file storage, and block storage, tailored to meet the diverse needs of their customers. Organizations can leverage public cloud storage to store various types of data, from application data and user files to backups, archives, and multimedia content.

Public cloud solutions ensure data integrity and security through robust measures like encryption, IAM, MFA, and compliance with regulations such as GDPR. Overall, public cloud storage enables organizations to benefit from the advantages of cloud computing, including on-demand resource provisioning, pay-as-you-go pricing, and global accessibility, while offloading the management of storage infrastructure to the cloud provider.
