The primary storage platform (PSP) market addresses the need of I&O leaders to operate and support standardized enterprise storage products, along with platform-native service capabilities to support structured data applications. PSP products like primary enterprise storage arrays provide mandatory and common enterprise-class primary storage features and capabilities needed to support the platform. Platform-native services like storage as a service (STaaS) and ransomware protection, with PSP product capabilities, are required to support platform-native services. The PSP market has emerged at the convergence of two major enterprise storage market developments: the evolution of the PSP product market in conjunction with the demand for hybrid, multidomain platform-native storage services, extending on-premises services to public cloud, edge and colocation environments.
Public cloud storage is infrastructure as a service (IaaS) that provides block, file, object and hybrid cloud storage services delivered through various protocols. The services are stand-alone, but often used in conjunction with compute and other IaaS products. The services are priced based on capacity, data transfer and/or number of requests. The services provide on-demand storage capacity and self-provisioning capabilities. Stored data exists in a multitenant environment, and users access that data through the block, network and REST protocols provided by the services.
