What is AWS Storage Gateway?

AWS Storage Gateway is a hybrid cloud storage service that provides on-premises access to cloud storage from AWS. It allows businesses to seamlessly connect their on-premises environments with AWS cloud storage solutions, enabling them to store, access, and manage their data effectively across both environments. This architecture is beneficial for organizations looking to leverage the scalability and durability of the cloud while still maintaining local access for specific applications or compliance needs.

By using various configurations, such as file gateways, volume gateways, and tape gateways, AWS Storage Gateway accommodates different storage use cases, including file storage, block storage, and backup/tape storage. This integration helps facilitate smoother transitions to cloud storage, enhances data backup options, and supports content delivery without requiring full data migration to the cloud.

The other options mentioned do not accurately describe the function or purpose of AWS Storage Gateway. For example, while a data migration service focuses specifically on moving data from one location to another, the Storage Gateway is primarily about ongoing access and integration. Additionally, serverless computing involves executing code without the need to manage infrastructure, which is unrelated to the storage capabilities of the Storage Gateway. Lastly, a monitoring solution deals with the observability of cloud resources rather than providing direct access to storage solutions.
