The abstract of the patent published by the U.S. Patent and Trademark Office states: “Technologies are provided for supporting storage device write barriers. A host computer can be configured to transmit a write barrier command to a storage device to indicate that one or more data access commands should be processed before one or more other data access commands are processed. For example, a host computer can transmit one or more data access commands to a storage device. The host computer can then transmit a write barrier command to the storage device. The storage device can be configured to receive the write barrier command and to associate a write barrier with the one or more data access commands. The host computer can continue to transmit additional data access commands to the storage device. However, the storage device will not process the additional data access commands until after the one or more data access commands associated with the write barrier have been processed.”

For example, data may be separated into sensitive data and nonsensitive data, and at least the sensitive data is securely delivered to a data storage service. The data storage service generates a token that is representative of the sensitive data and stores the sensitive data as secure data. The data storage service may deliver the token to an entity that also receives the nonsensitive data, and the entity may use the token in place of the sensitive data. In some implementations, different tokens are generated each time the same piece of sensitive data is submitted for storage as secure data. Further, in some implementations, An expiration time may be assigned to sensitive data, and expired data and associated tokens may be deleted.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods are provided for providing a consistent experience for users of cloud-based block storage volumes. While cloud storage aims to remove hardware considerations for an end user’s experience, block storage performance can nevertheless vary according to hardware configuration, such as the specific model of underlying hardware used to support a volume or the specific network location of that hardware. Embodiments of the present disclosure address that inconsistent performance by associating a volume with a performance profile, which can represent a desired distribution of performance for the volume. Each read or write can be compared to the profile, and may be selectively delayed to match the desired performance. This enables the cloud provider to vary physical hardware or network configurations without effect on block storage performance from the point of view of an end user.”
