How public, private and hybrid cloud storage compare.Ĭloud service providers maintain large data centers in multiple locations around the world. An enterprise-level cloud storage system should be scalable to suit current and future needs, accessible from anywhere and application-agnostic. For example, private workloads must access and interact with public cloud storage providers, so compatibility, and reliable and ample network connectivity are important factors. Despite the benefits of hybrid clouds, they present technical, business and management challenges. A hybrid environment also makes it easier to handle seasonal or unanticipated spikes in data creation or access by cloud bursting to the external storage service and avoiding having to add in-house storage resources.Īdoption of the hybrid cloud model has increased in recent years. An organization might, for example, store actively used and structured data in an on-premises private cloud and unstructured and archival data in a public cloud. The model offers businesses flexibility and more data deployment options.

This cloud storage option is a mix of private cloud storage and third-party public cloud storage services, with a layer of orchestration management to operationally integrate the two platforms. Private clouds are appropriate for users who need customization and more control over their data or who have stringent data security or regulatory requirements. Internally hosted private cloud storage implementations emulate some of the features of commercial public cloud services, providing easy access and allocation of storage resources for business users, as well as object storage protocols. A private cloud storage service is an in-house storage resource deployed as a dedicated environment protected behind a firewall. Google Cloud Storage Nearline for cold data and.Amazon Glacier for deep archival or cold storage.This market sector is dominated by the following services: In many cases, there are also transaction charges based on frequency and the volume of data being accessed. Customers generally pay on a per-use basis, similar to the utility payment model. Data is stored in the service provider's data centers with storage data spread across multiple regions or continents. These storage services provide a multi-tenant storage environment that is most suited for unstructured data on a subscription basis. There are three main cloud storage options, based on different access models: public, private and hybrid. Cloud storage has radically driven down the per-gigabyte cost of storage, but cloud storage providers have added operating expenses that can make the technology considerably more expensive, depending on how it's used. Organizations opting for cloud storage eliminate the need to buy, manage and maintain in-house storage infrastructure. Storage services are provided on demand in the cloud, with capacity increasing and decreasing as needed. Cloud-based data is stored in logical pools across disparate, commodity storage servers located on premises or in a data center managed by a third-party cloud provider.Ĭloud service providers manage and maintain data transferred to the cloud. Users generally pay for their cloud data storage on a per-consumption, monthly rate.Ĭloud storage is based on a virtualized storage infrastructure with accessible interfaces, near-instant elasticity and scalability, multi-tenancy, and metered resources. Cloud storage is a service model in which data is transmitted and stored on remote storage systems, where it is maintained, managed, backed up and made available to users over a network - typically, the internet.
