A pharmaceutical company is developing a new drug.

AWS Storage Gateway is a hybrid cloud storage service that allows you to seamlessly integrate your on-premises applications with AWS cloud storage. Volume Gateway is a type of Storage Gateway that presents cloud-backed iSCSI block storage volumes to your on-premises applications. Volume Gateway operates in either cache mode or stored mode. In cache mode, your primary data is stored in Amazon S3, while retaining your frequently accessed data locally in the cache for low latency access. In stored mode, your primary data is stored locally and your entire dataset is available for low latency access on premises while also asynchronously getting backed up to Amazon S3.

For the pharmaceutical company’s use case, cache mode is the most suitable option, as it meets the following requirements:

It reduces the need to scale the on-premises storage infrastructure, as most of the data is stored in Amazon S3, which is scalable, durable, and cost-effective.

It provides low latency access to the subset of the data that the researchers regularly require, as it is cached locally in the Storage Gateway appliance.

It does not require the entire dataset to be accessed on a daily basis, as it is stored in Amazon S3 and can be retrieved on demand.

It offers flexible data protection and recovery options, as it allows taking point-in-time copies of the volumes using AWS Backup, which are stored in AWS as Amazon EBS snapshots.

Therefore, the solutions architect should recommend deploying an AWS Storage Gateway volume gateway with cached volumes with an Amazon S3 bucket as the target storage and migrating the data to the Storage Gateway appliance.
