AWS Storage Gateway: Seamless Integration with On-Premises Infrastructure
Question
MSP Bank, Limited is a leading Japanese monetary institution that provides a full range of financial products and services to both institutional and individual customers.
It is headquartered in Tokyo.
MSP Bank is hosting their existing infrastructure on premise. MSP bank has lot of web applications, databases and data warehouse built on Teradata, NoSQL databases, and other types of data stores.
MSP bank has lot of data assets in terms of logs, documents; excel files, CSV files, PDF documents and others.
MSP Bank wants to provide seamless integration with data security features between their on-premises IT environment and the AWS storage infrastructure.
MSP bank considers AWS Storage Gateway to address the integration. MSP Bank looking at interface into Amazon Simple Storage Service (Amazon S3) and combines a service and a virtual software appliance through which the team can store and retrieve objects in Amazon S3 using industry-standard file protocols such as Network File System (NFS) and Server Message Block (SMB)
The gateway provides access to objects in S3 as files or file share mount points.
Which option of Storage Gateway supports this feature?

A. B. C. D.Answer: B.
Option A is incorrect.
A volume gateway provides cloud-backed storage volumes that you can mount as Internet Small Computer System Interface (iSCSI) devices from your on-premises application servers.
The gateway supports the following volume configurations:
Cached volumes - You store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally.
Cached volumes offer a substantial cost savings on primary storage and minimize the need to scale your storage on- premises.
You also retainlow-latency access to your frequently accessed data.
Stored volumes - If you need low-latency access to your entire dataset, first configure your on-premises gateway to store all your data locally.
Then asynchronously back up point-in- time snapshots of this data to Amazon S3
This configuration provides durable and inexpensive offsite backups that you can recover to your local data center or Amazon EC2
For example, if you need replacement capacity for disaster recovery, you can recover the backups to Amazon EC2

A file gateway supports a file interface into Amazon Simple Storage Service (Amazon S3) and combines a service and a virtual software appliance.
By using this combination, store and retrieve objects in Amazon S3 using industry-standard file protocols such as Network File System (NFS) and Server Message Block (SMB)
The software appliance, or gateway, is deployed into your on-premisesenvironment as a virtual machine (VM) running on VMware ESXi or Microsoft Hyper-V hypervisor.
The gateway provides access to objects in S3 as files or file share mount points.
With a file gateway, you can do the following:
You can store and retrieve files directly using the NFS version 3 or 4.1 protocol.
You can store and retrieve files directly using the SMB file system version, 2 and 3 protocol.
You can access your data directly in Amazon S3 from any AWS Cloud application or service.
You can manage your Amazon S3 data using lifecycle policies, cross-region replication, and versioning.
You can think of a file gateway as a file system mount on S3

With a tape gateway, cost-effectively and durably archive backup data in Glacier.
A tape gateway provides a virtual tape infrastructure that scales seamlessly with your business needs and eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure.
https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.htmlThe option of Storage Gateway that supports the feature of providing access to objects in Amazon S3 as files or file share mount points using industry-standard file protocols such as NFS and SMB is the File Gateway.
AWS Storage Gateway is a hybrid cloud storage service that provides seamless and secure integration between an organization's on-premises IT environment and the AWS cloud storage infrastructure. The service provides different types of gateways that can be deployed on-premises as virtual or hardware appliances to provide different types of storage access.
The Volume Gateway option of Storage Gateway provides block storage to applications using the iSCSI protocol, enabling it to store and access data volumes as block devices. The Volume Gateway provides two modes of operation, i.e., Cached volumes and Stored volumes.
The Tape Gateway option of Storage Gateway provides an on-premises virtual tape library that allows backup applications to store and retrieve virtual tapes using iSCSI connectivity.
The File Gateway option of Storage Gateway is designed to provide file storage in the cloud by offering a file interface to Amazon S3 using industry-standard file protocols such as NFS and SMB. The File Gateway can be deployed as a virtual machine or as a hardware appliance, and it provides two types of file shares:
NFS File Share - An NFS file share allows applications to access files in Amazon S3 as NFSv3 or NFSv4.1 mount points. This file share is suitable for Linux-based applications.
SMB File Share - An SMB file share allows Windows-based applications to access files in Amazon S3 as UNC paths. This file share supports SMBv2 and SMBv3 protocols.
In conclusion, the correct option of Storage Gateway that supports the feature of providing access to objects in Amazon S3 as files or file share mount points using industry-standard file protocols such as NFS and SMB is the File Gateway.
