Understanding AWS Storage Gateway

While many businesses continue to migrate their entire environments to the AWS cloud as part of the current cloud migration trend, some still place a significant amount of their reliance on ageing on-premise data centres. These businesses only have one choice when it comes to using AWS—a hybrid cloud solution—whether they are constrained by current licencing or are forced to stick with working with the on-site bare metal hardware due to stringent compliances.

There is work to be done on each of these hybrid clouds, and you must consider capital and operational costs. Maintaining them can take a lot of time and money. However, they do have some benefits, such as the capacity to quickly adapt and change course when necessary for business. Because you are actually getting the best of both worlds, hybrid clouds are an intriguing option.

In this article, we’ll discuss AWS Storage Gateway, one of the AWS services that many hybrid clouds can greatly use. We’ll examine what it is, what benefits it can provide for your company, and the best ways to use it.

Storage Gateway by AWS

Your applications may use AWS cloud storage services like S3, Glacier, EBS, etc. with the help of the hybrid cloud storage solution known as AWS Storage Gateway, which is installed on-premises. By utilising storage protocols like NFS, iSCSI, and SMB, it can be set up as a virtual machine or a hardware gateway appliance and offers a number of other functions in addition to highly efficient data transmission capabilities.

When it comes to using Storage Gateway, there are many advantages. It features encryption, data security, and bandwidth control and provides exceptionally low latency network and disc performance as a result of its local caching.

You may have your data used by different analytics, machine learning, logging, monitoring, and other products since Storage Gateway is natively linked with many other AWS services. Your data will gain from the security, scalability, availability, and durability of all the cloud services it uses (Amazon S3 and Glacier are built for 99.999999999% durability).

Utilizing Storage Gateway lowers the maintenance costs associated with your on-premise storage solution, which has significant positive effects on your company as a whole. Your organisation may become more adaptable and more reliant on the global infrastructure and goods offered by AWS by doing away with the astronomical upfront cost of hardware and switching to an operating expenditures model.

Types of AWS Gateway Storage

The three primary forms of AWS Storage Gateway—a File Gateway, a Volume Gateway, and a Tape Gateway—are each created to meet certain needs and specifications.


An on-premises application that you already have can be integrated with Amazon S3 using a File Gateway kind of Storage Gateway. For any tasks requiring dealing with objects, it offers NFS (Network File System) and SMB (Server Message Block) access to data in S3.

You may pick from a variety of S3 storage classes thanks to File Gateway’s reliance on AWS S3, and you can also apply different rules to your data or even duplicate it across the globe inside other accessible regions.

Cases of Use

A useful option for many hybrid cloud applications is File Gateway. For instance, File Gateway makes it simple for you to migrate the data to S3 and ingest it into something like EMR or Athena if your business does a lot of big data analytics and relies on both on-premise and the AWS cloud.

The generated data may also be saved in S3, making it accessible to your on-premise applications and usable for business intelligence and other purposes.

Another use for this service is machine learning, particularly if you utilise AWS services like SageMaker, Forecast, or Rekognition.

Because it has NFS and SMB interfaces, File Gateway may also be used to do straightforward backups to the cloud. Depending on the needs, retention policies may be utilised to move the data to different storage classes to save money. Your existing backup operations can begin dumping data straight to S3.


Volume Gateways provide the iSCSI block storage to your on-premises application as opposed to File Gateways, which are utilised to access objects. Volume Gateways are available in two separate operational modes: stored and cached, and they let you save point-in-time backups of your volumes as EBS snapshots.

Stored volumes preserve an asynchronous copy of your data in the S3 bucket while making your whole data locally accessible on the gateway.

Only the most current data is kept in the local cache for cached volumes, which store the whole volume in the S3 bucket.

Cases of Use

Volume Gateways are frequently used for disaster recovery and local data backup. To fast recover from an incident that harmed your on-premise data centre, you may easily replicate an EBS volume and link it to an active EC2 instance if you have a snapshot of your data on AWS. Additionally connected with the AWS Backup service, Volume Gateways make backup administration simpler.

Volume Gateways are also a fantastic option when moving application data to the cloud. You can quickly migrate your on-premise data to EBS volumes and use it in the cloud thanks to snapshots.


An industry-standard Virtual Tape Library based on iSCSI serves as Tape Gateway (VTL). It is installed on-premises and consists of virtual tape drives and media changers, allowing you to stick with your current backup procedures. Your data is simultaneously written to virtual tapes that are kept in dependable S3 buckets, and when frequent access is no longer required, it is prepared to be archived to Glacier (further lowering the storage cost).

Numerous popular backup programmes, including Dell EMC NetWorker, Microsoft System Center Data Protection Manager, and many more, are compatible with tape gateway.

Cases of Use

Without having to significantly alter your current backup procedure, tape gateways are usually used to replace outdated tape backup systems. Physical tape backup solutions required expensive gear, and there were significant problems with the tape management procedure. Your offline data was rendered unavailable and required time and money to ship to an off-site storage facility. Durability was another issue, which is entirely different when utilising S3 and Glacier.

Pricing for AWS Storage Gateway

Your gateway will charge you $0.01 per GB of data written to AWS storage for all three categories, with a monthly cap of $125.00 per gateway. Additionally, each variety will have certain unique fees associated with it.

File Gateways will generate costs for all data kept in S3 buckets; you will be charged according to S3 pricing for both storage and requests.

You will pay for volume gateways ($0.023 per GB of data kept in volumes), as well as snapshots ($0.05 per GB of data saved), which are stored and invoiced like EBS snapshots.

You will pay $0.023 per gigabyte for virtual tape storage and $0.004 per gigabyte for archived virtual tape storage using Tape Gateways (these prices reflect S3 and Glacier cost). Additionally, you will be charged $0.01 per GB if you need to retrieve your data. Data archiving is completely free.


With the help of the AWS Storage Gateway service, you may fully utilise cloud storage services by connecting your on-premises applications to them. It is a very adaptable solution that can handle a broad range of use cases, from basic backups and disaster recovery to comprehensive data migrations or employing cloud resources for many different workloads. There are three main varieties available, each tailored to meet a particular purpose. Storage Gateway is a service to consider if your business uses a hybrid cloud solution that integrates both an on-premise data centre and the AWS.
