Definition - What does Cloud Storage Gateway mean?
A cloud storage gateway is a software or hardware networking device that provides connectivity and protocol translation services between a cloud storage service provider and local customer application. It is implemented on a local machine or application to facilitate data transfer between incompatible protocols, security and compression services.
A cloud storage gateway is also known as a cloud storage controller or cloud storage appliance.
Techopedia explains Cloud Storage Gateway
A cloud storage gateway is designed to provide interoperability between different data protocols used in a client/server cloud architecture. It allows interoperability between the application programming interface (API) of a client's REST/SOAP-based data storage and Internet SCSI (iSCSI), Fiber Channel (FC) and other cloud storage server system protocols.
Generally, cloud storage gateways are implemented as software gateways that provide a suite of services to facilitate seamless data transfer and retrieval between remote cloud storage servers, data compression for faster transfer, version management and control of entire storage snapshots and run-time encryption, which ensures secure data transmission.
