Seamless Integration and Data Security with AWS Storage Gateway
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 is looking at gateway interface which provides cloud-backed storage volumes that you can mount as Internet Small Computer System Interface (iSCSI) devices from your on-premises application servers.
Also store data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally thereby offer a substantial cost savings on primary storage and minimize the need to scale your storage on-premises.
How can this be achieved? select 2 options.

A. B. C. D.Answer: A,B.
Option A is correct.
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.
https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.htmlMSP Bank is looking for a seamless integration with data security features between their on-premises IT environment and the AWS storage infrastructure. The AWS Storage Gateway service can help MSP Bank in achieving this goal.
AWS Storage Gateway is a hybrid cloud storage service that enables on-premises applications to use AWS cloud storage. It connects an on-premises software appliance with cloud-based storage to provide seamless and secure integration between the on-premises environment and AWS cloud storage.
The gateway interface provided by AWS Storage Gateway allows cloud-backed storage volumes to be mounted as iSCSI devices from on-premises application servers. This interface provides three types of volumes:
Volume Gateway: This type of gateway provides cloud-backed storage volumes that can be mounted as iSCSI devices from on-premises application servers. It stores data in Amazon S3 and retains a copy of frequently accessed data subsets locally, thereby offering a substantial cost saving on primary storage and minimizing the need to scale storage on-premises.
Cached Volumes: This type of gateway stores frequently accessed data subsets locally, while storing the entire dataset in Amazon S3. The gateway stores the most recently accessed data in a local cache, which minimizes the access time to frequently accessed data and reduces the number of requests that are sent to Amazon S3.
Stored Volumes: This type of gateway stores the entire dataset on-premises and asynchronously backs up point-in-time snapshots of this data to Amazon S3. This provides durable and low-latency access to entire datasets while still providing off-site backups.
Therefore, the two options that can help MSP Bank in achieving their goal of seamless integration with data security features between their on-premises IT environment and the AWS storage infrastructure are Volume Gateway and Cached Volumes.
