Exam AWS Certified Solutions Architect - Professional topic 1 question 880 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 880
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company is planning to migrate an application from on premises to the AWS Cloud. The company will begin the migration by moving the application's underlying data storage to AWS. The application data is stored on a shared file system on premises, and the application servers connect to the shared file system through
SMB.
A solutions architect must implement a solution that uses an Amazon S3 bucket for shared storage. Until the application is fully migrated and code is rewritten to use native Amazon S3 APIs, the application must continue to have access to the data through SMB. The solutions architect must migrate the application data to
AWS to its new location while still allowing the on-premises application to access the data.
Which solution will meet these requirements?

  • A. Create a new Amazon FSx for Windows File Server file system. Configure AWS DataSync with one location for the on-premises file share and one location for the new Amazon FSx file system. Create a new DataSync task to copy the data from the on-premises file share location to the Amazon FSx file system.
  • B. Create an S3 bucket for the application. Copy the data from the on-premises storage to the S3 bucket.
  • C. Deploy an AWS Server Migration Service (AWS SMS) VM to the on-premises environment. Use AWS SMS to migrate the file storage server from on premises to an Amazon EC2 instance.
  • D. Create an S3 bucket for the application. Deploy a new AWS Storage Gateway file gateway on an on-premises VM. Create a new file share that stores data in the S3 bucket and is associated with the file gateway. Copy the data from the on-premises storage to the new file gateway endpoint.

The answer is A. You cannot migrate data to S3 at this time per the question. You must copy the data to AWS to a solution that allows SMB. Later, once they modify the application to use S3, will they then migrate the data to S3. AWS DataSync was built for a solution like this. It can migrate from an on-premises SMB server to FSx for Windows File Server. DataSync will replicate on a schedule and keep the target in sync with the Source based on that replication schedule. https://docs.aws.amazon.com/datasync/latest/userguide/how-datasync-works.html

Assuming that underlying data on prem will continue to be updated during the migration proccess, "A" works better than "D". Option "D" does not talk about keeping the data in synch

D would work if it weren't windows. It will not really work well. A on the other hand works. Yes we have costs for FX and we need the datasync but it works even with windows.

One solution that can meet these requirements is to use Amazon S3 with the AWS Storage Gateway service. AWS Storage Gateway is a hybrid storage service that allows you to store data both on-premises and in the AWS cloud. It provides file-based storage, using the SMB protocol, which is compatible with the on-premises application's existing file access method. The Storage Gateway service can be configured as a File Gateway, which provides a SMB file share that is backed by an Amazon S3 bucket.

Since question states that app will be rewritten to use native S3 APIs, I would not pick FSX, rather, use Storage GW/File Gateway and the data will reside in S3. https://stackoverflow.com/questions/71413007/aws-fsx-vs-s3-file-gateway SMB over SGW/FGW is reported way slower than FSX but this is not an issue within the question.

Answer D. SMB it's supported for Storage Gateway to store and retrieve files from S3 bucket: https://aws.amazon.com/about-aws/whats-new/2018/06/aws-storage-gateway-adds-smb-support-to-store-objects-in-amazon-s3/?nc1=h_ls

D because if you use Datasync, then you are maintaining two locations and have not actually migrated anything, just replicating. D will allow a migration and permanent switch from on prem to AWS storage.

Will go with D. B and C ruled out as you need to continue accessing the data during copy. A does migrate date to S3.
