AWS Storage Gateway
| Overview |
|---|
| AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. Customers use Storage Gateway to simplify storage management and reduce costs for key hybrid cloud storage use cases. These include moving backups to the cloud, using on-premises file shares backed by cloud storage, and providing low latency access to data in AWS for on-premises applications. |
1. A company currently hosts a lot of data on their On-premises location. They want to start storing backups of this data on AWS. How can this be achieved in the most efficient way possible?
A. Create EBS Volumes and store the data.
B. Create EBS Snapshots and store the data.
C. Make use of Storage Gateway Stored volumes.
D. Make use of Amazon Glacier.
C. Make use of Storage Gateway Stored volumes.
AWS Storage Gateway connects an on-premises software appliance with cloud-based storage to provide seamless integration with data security features between your on-premises IT environment and the AWS storage infrastructure. You can use the service to store data in the AWS Cloud for scalable and cost-effective storage that helps maintain data security. It has two types of configuration, cached volumes, and stored volumes. Our requirement is tostart storing backups of the on-premises data to S3. Incachedvolumes, you store your data in S3 and retain a copy of frequently accessed data subsets locally. This means that we are not storing the backups on S3 but theactual primary dataitself. But in thestoredmode,your primary data is stored locally and your entire dataset is available for low-latency access whileasynchronously backed up to AWS S3.
2. A company has a lot of data hosted on their On-premises infrastructure. Running out of storage space, the company wants a quick win solution using AWS. Which of the following would allow easy extension of their data infrastructure to AWS?
A. The company could start using Gateway Cached Volumes.
B. The company could start using Gateway Stored Volumes.
C. The company could start using the Simple Storage Service.
D. The company could start using Amazon Glacier.
A. The company could start using Gateway Cached Volumes.
Volume Gateways and Cached Volumes can be used to start storing data in S3. AWS Documentation mentions the following: 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 retain low-latency access to your frequently accessed data. For more information on Storage Gateways, please visit the following URL: https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.html Note: The question states that they are running our of storage space and they need a solution to store data with AWS rather than a backup. So for this purpose, gateway cached volumes are appropriate which will help them to avoid scaling their on-premises data center and allows them to store on AWS storage service while having the most recent files available for them at low latency.
3. A company needs to extend their storage infrastructure to the AWS Cloud. The storage needs to be available as iSCSI devices for on-premises application servers. Which of the following would be able to fulfill this requirement?
A. Create a Glacier vault. Use a Glacier Connector and mount it as an iSCSI device.
B. Create an S3 bucket. Use an S3 Connector and mount it as an iSCSI device.
C. Use the EFS file service and mount the different file systems to the on-premises servers.
D. Use the AWS Storage Gateway-cached volumes service.
D. Use the AWS Storage Gateway-cached volumes service.
By using cached volumes, you can use Amazon S3 as your primary data storage, while retaining frequently accessed data locally in your storage gateway. Cached volumes minimize the need to scale your on-premises storage infrastructure, while still providing your applications with low-latency access to their frequently accessed data. You can create storage volumes up to 32 TiB in size and attach to them as iSCSI devices from your on-premises application servers. Your gateway stores data that you write to these volumes in Amazon S3 and retains recently read data in your on-premises storage gateway’s cache and upload buffer storage.

4. A customer has a single 3-TB volume on-premises that is used to hold a large repository of images and print layout files. This repository is growing at 500GB a year and must be presented as a single logical volume. The customer is becoming increasingly constrained with their local storage capacity and wants an offsite backup of this data, while maintaining low-latency access to their frequently accessed data. Which AWS Storage Gateway configuration meets the customer requirements?
A. Gateway-Cached Volumes with snapshots scheduled to Amazon S3
B. Gateway-Stored Volumes with snapshots scheduled to Amazon S3
C. Gateway-Virtual Tape Library with snapshots to Amazon S3
D. Gateway-Virtual Tape Library with snapshots to Amazon Glacier
A. Gateway-Cached Volumes with snapshots scheduled to Amazon S3
Gateway-cached volumes let you use Amazon Simple Storage Service (Amazon S3) as your primary data storage while retaining frequently accessed data locally in your storage gateway. Gateway-cached volumes minimize the need to scale your on-premises storage infrastructure, while still providing your applications with low-latency access to their frequently accessed data. You can create storage volumes up to 32 TiB in size and attach to them as iSCSI devices from your on-premises application servers. Your gateway stores data that you write to these volumes in Amazon S3 and retains recently read data in your on-premises storage gateway’s cache and upload buffer storage.

5. There is a requirement for an iSCSI device and the legacy application needs local storage. Which of the following can be used to meet the demands of the application?
A. Configure the Simple Storage Service.
B. ConfigureS torage Gateway Cached volume.
C. Configure Storage Gateway Stored volume.
D. Configure Amazon Glacier.
C. Configure Storage Gateway Stored volume.
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.

S3 and Glacier are not used for this purpose. Volume gateway provides an iSCSI target, which enables you to create volumes and mount them as iSCSI devices from your on-premises or EC2 application servers. The volume gateway runs in either a cached or stored mode.
In the cached mode, your primary data is written to S3, while retaining your frequently accessed data locally in a cache for low-latency access. In the stored mode, your primary data is stored locally and your entire dataset is available for low-latency access while asynchronously backed up to AWS.
6. Your company would like to leverage the AWS storage option and integrate it with the current on-premises infrastructure. Besides, due to business requirements, low latency access to all the data is a must. Which of the following options would be best suited for this scenario?
A. Configure the Simple Storage Service.
B. Configure Storage Gateway Cached Volume.
C. Configure Storage Gateway Stored Volume.
D. Configure Amazon Glacier.
C. Configure Storage Gateway Stored Volume.
