Storage Gateway is a hybrid storage service that allows you to migrate data into AWS, extending on-premise storage capacity using AWS.
- It is used when you want to integrate the existing on-premise application data with AWS cloud storage services without fully migrating to AWS. Applications in your network can access data in the cloud.
- Data may be moved to AWS and cached them locally at the on-premise data center.
- Key Management Service (KMS) can encrypt data at rest in the cloud.
- CloudWatch can be used for monitoring, and CloudTrail can be used for logging account activity.
