Storage as a Service is generally seen as a good alternative for a small or mid-sized business that lacks the capital budget and/or technical personnel to implement and maintain their own storage infrastructure. SaaS is also being promoted as a way for all businesses to mitigate risks in disaster recovery, provide long-term retention for records and enhance both business continuity and availability.
Storage service is built to provide applications, services and organizations with access to offsite storage capacity that can be provisioned instantly, is flexible in scaling automatically at run time and is globally accessible.
Storage service is provided, hosted and managed by the storage service provider (SSP), and it works on the combination of storage servers, which are designed on storage virtualization architecture. This technique allows a single storage server to create multiple logical and virtual drives with scalable capacity and tight coupling. End users and applications access the logical storage by the online management interface or integrating vendor APIs with the application and are only billed for the storage capacity metered.
Storage services are delivered in public and hybrid storage models.
