We shall now delve into some of these pivotal features, elucidating their profound impact on the operational efficacy of Storage Gateway.
Fully Managed Intelligent Cache
A cornerstone of Storage Gateway’s performance and efficacy is its fully managed, intelligent cache mechanism. This sophisticated cache is strategically deployed on the local gateway appliance, serving as a high-speed repository that provides low-latency access to data stored within the AWS platform. Its intelligence lies in its ability to proactively maintain a cache of frequently read data, along with recently written data that is pending upload to the cloud.
The gateway employs a sophisticated read-through and write-back cache architecture. When an on-premises application requests data, the gateway first checks its local cache. If the data is present (a cache hit), it is served immediately, ensuring minimal latency. If not (a cache miss), the gateway transparently fetches the data from AWS and stores it in the local cache for future rapid access (read-through). For write operations, data is first committed to the local cache, and the write operation is acknowledged back to the on-premises application instantly, significantly reducing application latency. Subsequently, the gateway asynchronously and durably copies this data to the cloud (write-back), ensuring data persistence in AWS while maintaining high performance for local operations. This asynchronous transfer minimizes the impact of network latency on application performance, providing a seamless experience for on-premises workloads.
Pervasive Standard Storage Protocol Support
AWS has meticulously designed this hybrid cloud storage solution with an emphatic focus on seamless interoperability, ensuring it seamlessly connects local production and backup applications with widely adopted standard storage protocols.

The key standard storage protocols supported include:
- Network File System (NFS): A distributed file system protocol widely used in Unix/Linux environments. File Gateway presents file shares as NFS mount points.
- Server Message Block (SMB): A network file sharing protocol primarily used by Microsoft Windows clients. File Gateway presents file shares as SMB shares.
- Internet Small Computer System Interface (iSCSI): A protocol that allows clients to send SCSI commands over a TCP/IP network, providing block-level storage access. Volume Gateway utilizes iSCSI to present block volumes.
- Internet Small Computer System Interface – Virtual Tape Library (iSCSI-VTL): An extension of iSCSI that emulates a traditional tape library, allowing existing backup software to write to virtual tapes over IP networks. Tape Gateway leverages iSCSI-VTL.
This comprehensive protocol support is critical because it means that companies can implement this hybrid storage solution without having to modify their existing applications. A backup server, for example, can continue to write to what it perceives as a tape library, even though the data is ultimately flowing to Amazon S3 through a Storage Gateway virtual appliance. This «no-code change» approach dramatically simplifies adoption and reduces the inherent risks and costs associated with extensive application refactoring.
Secure and Optimized Data Transference
Data security and transfer efficiency are paramount concerns in hybrid cloud environments. Storage Gateway is engineered to securely upload changed data and download requested data in the most robust fashion.

The Economic Blueprint: Understanding AWS Storage Gateway Pricing Mechanisms
A thorough understanding of the AWS Storage Gateway pricing structure is paramount for organizations seeking to optimize their cloud expenditures and accurately forecast operational costs within a hybrid cloud environment. Unlike a single, monolithic fee, AWS Storage Gateway pricing is meticulously delineated into distinct components, each reflecting different aspects of resource consumption and service utilization. These components collectively articulate the financial blueprint for leveraging this crucial hybrid cloud solution.
The overarching pricing structure for AWS Storage Gateway comprises the following fundamental components:
Storage Pricing: The Cost of Cloud Residenc
Storage Pricing comprehensively encapsulates the fees associated with all underlying AWS storage services utilized in conjunction with the gateway. This includes, but is not limited to, the costs incurred for storing data in Amazon Simple Storage Service (S3) for File and Tape Gateways, and Amazon Elastic Block Store (EBS) for Volume Gateway snapshots. It also includes the cost of any local disk storage provisioned on the gateway appliance for cache or stored volumes. This component is typically calculated based on the volume of data stored (per GB) and the duration of storage (per month), varying by the specific AWS storage class employed (e.g., S3 Standard, S3 Intelligent-Tiering, S3 Glacier Deep Archive). The more data an organization stores in the cloud via the gateway, the higher this particular cost component will be.
Request Pricing: The Cost of Data Operations
Request Pricing pertains to the charges levied for data operations performed on AWS Storage services via the gateway. This component accounts for the API calls and interactions that the Storage Gateway appliance makes to AWS services (like S3 PUT/GET requests, EBS snapshot operations) on behalf of your on-premises applications. For instance, when a file is written to a File Gateway share, the gateway might perform S3 PUT requests to store it as an object. When a file is read, it translates into S3 GET requests. These charges are typically metered by the number of requests (e.g., per 1,000 requests) and can vary depending on the type of request (e.g., PUT, GET, LIST) and the underlying AWS storage service.
Data Transfer Pricing: The Cost of Egress
Data Transfer Pricing encompasses the charges incurred for any data transferred out of the AWS Storage service back into the gateway appliance (i.e., data egress from AWS). This is a critical component to monitor, as AWS generally charges for data moving out of its regions and services (egress), while data moving into AWS (ingress) is typically free or very low cost. For example, if an on-premises application requests a file that is not in the local gateway cache, the gateway will download it from S3, incurring data transfer egress charges. This component is usually metered per GB transferred. Careful planning around data access patterns and efficient caching strategies can help mitigate these costs.
Hardware Appliance Pricing: The Physical Deployment Cost
Finally, if AWS Storage Gateway is deployed as a physical appliance (rather than a virtual machine on existing on-premises hypervisors), an additional cost is incurred for purchasing the appliance itself. This is a one-time upfront hardware acquisition cost, distinct from the ongoing operational costs of the AWS service. The physical appliance is designed for environments where a virtual machine deployment is not feasible or desired, providing a dedicated, pre-configured hardware solution.
Now, let us delve into the pricing specifics per type of Storage Gateway to provide a more granular understanding:
a. Amazon S3 File Gateway Pricing
For Amazon S3 File Gateway, the core cost driver for storage is the underlying Amazon S3 object storage, and billing is done accordingly based on the S3 pricing model (e.g., S3 Standard, S3 Intelligent-Tiering, S3 Glacier, S3 Glacier Deep Archive).
- Beyond S3 storage, the data that the gateway stores to AWS storage is also billed at a specific rate per GB. This represents the data processed by the gateway and transferred to S3, often at a rate like $0.01/GB. This is distinct from the S3 storage cost itself and reflects the gateway service processing.
- Amazon S3 file operations are billed as S3 requests. For example, writing a file will incur S3 PUT request charges, and reading a file will incur S3 GET request charges. Standard S3 request rates apply.
b. Amazon FSx File Gateway Pricing
Amazon FSx File Gateway has a distinct hourly pricing model for the gateway itself, typically around $0.69/hour. This covers the running cost of the gateway service instance.
- The actual storage for the files is then billed according to the Amazon FSx for Windows File Server capacity consumed. This involves the cost of storage capacity, SSD IOPS, and potentially data deduplication, based on the chosen FSx configuration.
c. Volume Gateway Pricing
For Volume Gateway, the storage of snapshots in the cloud is billed as Amazon EBS snapshots. This means you pay for the changed block data stored in S3, which is optimized for cost-effective backups.
- There are also charges for data operations (API requests) when interacting with the volumes or snapshots.
- Data transfer egress charges apply when data is read from the cloud cache back to the on-premises gateway if it’s not already cached locally.
d. Tape Gateway Pricing
Tape Gateway billing primarily revolves around the virtual tapes stored in AWS.
- The virtual tapes are stored in S3 buckets, and the underlying storage cost is determined by the S3 storage classes utilized, particularly the lower-cost archival classes like Amazon S3 Glacier Flexible Retrieval and Glacier Deep Archive. This makes it a very economical option for long-term data retention.
- It involves only usage costs, omitting extra charges and upfront fees typically associated with physical tape infrastructure. You pay for the virtual tape storage, data written to the virtual tapes, and data retrieved from virtual tapes. There are no per-virtual-tape fees for archiving.
In summary, calculating AWS Storage Gateway costs requires a careful consideration of the gateway type, the volume of data stored, the frequency and volume of data operations, data transfer patterns, and whether a physical appliance is deployed. Understanding these distinct pricing components enables organizations to make informed decisions and manage their hybrid cloud storage expenditures effectively.
