networking technologies, southbound relates to the storage used by a gateway, whereas northbound is the storage provided by the gateway). As such, one may utilize a richer S3 implementation on northbound than the southbound supports. Disadvantages By using cloud storage gateways the complexity to use object storage is hidden, but that also hides some of the advantages of object storage: the ability of horizontal scaling ability to add high efficient metadata to the data content to use extended WORM and archiving capabilities of object storage As applications change to cloud-aware applications (aka called cloud native applications), cloud storage gateways will change from multiprotocol gateways to multi-cloud gateways, providing access to multiple cloud providers as well as multiple southbound protocols and act as relays between different clouds. Market the cloud storage gateway market was valued at over USD 2 billion and was predicted to reach USD 11 billion by 2026, based on a report by the market research firm Mordor intelligence.
