Cloud storage is a model of data storage in which the digital data is stored in logical pools and the physical environment is typically owned and managed by a hosting company.

Models of cloud storage

There are three main cloud storage models:

1. Public cloud storage services, such as Amazon's Simple Storage Service (S3), provide a multi-tenant storage environment that’s most suitable for unstructured data.

2. Private cloud storage services provide a dedicated environment protected behind an organization’s firewall.

Private clouds are appropriate for users who need customization and more control over their data.

3. Hybrid cloud storage is a combination of the other two models that includes at least one private cloud and one public cloud infrastructure.

An organization might, for example, store actively used and structured data in a private cloud and unstructured and archival data in a public cloud.

Architecture

Cloud storage is based on highly virtualized infrastructure and is like broader cloud computing in terms of accessible interfaces

Cloud storage typically refers to a hosted object storage service

Object storage services like Amazon S3 and Microsoft Azure Storage, object storage software like Openstack Swift, object storage systems like EMC Atmos, EMC ECS.

Cloud storage is

Made up of many distributed resources, but still acts as one – often referred to as federated storage clouds

Highly fault tolerant through redundancy and distribution of data

Highly durable through the creation of versioned copies

Typically eventually consistent with regard to data replicas
