Hybrid cloud storage

Hybrid cloud storage, in data storage, is a term for a storage infrastructure that uses a combination of on-premises storage resources with a public cloud storage provider. The on-premises storage is usually managed by the organization, while the public cloud storage provider is responsible for the management and security of the data stored in the cloud.^[1][2]

Hybrid cloud storage can be used to supplement an organization's internal storage resources, or it can be used as the primary storage infrastructure. In either case, hybrid cloud storage can provide organizations with greater flexibility and scalability than traditional on-premises storage infrastructure.^[1][2]

There are several benefits to using hybrid cloud storage, including the ability to cache frequently used data on-site for quick access, while inactive cold data is stored off-site in the cloud. This can save space, reduce storage costs and improve performance. Additionally, hybrid cloud storage can provide organizations with greater redundancy and fault tolerance, as data is stored in both on-premises and cloud storage infrastructure.^[1]

There are a few drawbacks to hybrid cloud storage as well, including the need to manage two separate storage infrastructures, and the potential for increased costs. Additionally, data stored in the cloud is subject to the security and privacy policies of the cloud storage provider.^[1] One challenge in transitioning from traditional storage systems to hybrid cloud storage is that the infinite capacity of the cloud, may lead to accumulation of wasted resources and to uncontrolled spending, if usage is not monitored carefully.^[3]
