Question 6 of 100 | ← Chapter 12

Q806. A financial services company wants to shut down two data centers and migrate more than 100 TB of data to AWS. The data has an intricate directory structure with millions of small files stored in deep hierarchies of subfolders. Most of the data is unstructured, and the company file storage consists of SMB-based storage types from multiple vendors. The company does not want to change its applications to access the data after migration.What should a solutions architect do to meet these requirements with the LEAST operational overhead?

Correct Answer: C. Use AWS DataSync to migrate the data to Amazon FSx for Windows File Server.

Explanation

To meet the requirements of migrating more than 100 TB of data with an intricate directory structure, consisting of millions of small files stored in deep hierarchies of subfolders, and minimizing operational overhead while ensuring seamless access for existing applications, the recommended solution is:C. Use AWS DataSync to migrate the data to Amazon FSx for Windows File Server.Option C provides the most suitable solution with the least operational overhead:\1. AWS DataSync is a data transfer service that simplifies and automates the migration of large amounts of data from on-premises storage systems to AWS. It can efficiently handle the migration of millions of small files with complex directory structures.\2. Amazon FSx for Windows File Server is a fully managed Windows file system that is accessible over the Server Message Block (SMB) protocol. It allows seamless integration with existing applications that rely on SMB-based storage.By using AWS DataSync to migrate the data to Amazon FSx for Windows File Server, the financial services company can accomplish the migration of their data with minimal operational overhead while ensuring compatibility with their existing applications.Here's why the other options are not the best fit for the given requirements:A. Using AWS Direct Connect to migrate the data to Amazon S3: While AWS Direct Connect provides a dedicated network connection between on-premises and AWS, migrating millions of small files with complex directory structures directly to Amazon S3 can result in operational challenges and may require additional data transfer mechanisms to ensure efficient migration.B. Using AWS DataSync to migrate the data to Amazon FSx for Lustre: Amazon FSx for Lustre is optimized for high-performance computing workloads and is not the best fit for storing unstructured data with millions of small files and deep hierarchical subfolders. This option would not provide the seamless SMB-based access required by the existing applications.D. Using AWS Direct Connect to migrate the data on-premises file storage to an AWS Storage Gateway volume gateway: While AWS Storage Gateway provides a hybrid cloud storage solution, it is designed for block and object storage, and using it for migrating SMB-based storage types may introduce complexities and additional configuration requirements.Therefore, the recommended solution for migrating the data to AWS with the least operational overhead while maintaining seamless access for existing applications is:C. Use AWS DataSync to migrate the data to Amazon FSx for Windows File Server.
