Topic 1 Question 76
A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-time analytics. A secure transfer is important because the data is considered sensitive. Which solution offers the MOST reliable data transfer?
AWS DataSync over public internet
AWS DataSync over AWS Direct Connect
AWS Database Migration Service (AWS DMS) over public internet
AWS Database Migration Service (AWS DMS) over AWS Direct Connect

- 正解だと思う選択肢: B
DMS is for databases and here refers to “JSON files”. Public internet is not reliable. So best option is B.

CORRECT The most reliable solution for transferring the data in a secure manner would be option B: AWS DataSync over AWS Direct Connect.
AWS DataSync is a data transfer service that uses network optimization techniques to transfer data efficiently and securely between on-premises storage systems and Amazon S3 or other storage targets. When used over AWS Direct Connect, DataSync can provide a dedicated and secure network connection between your on-premises data center and AWS. This can help to ensure a more reliable and secure data transfer compared to using the public internet.

- A SAN presents storage devices to a host such that the storage appears to be locally attached. ( NFS is, or can be, a SAN - https://serverfault.com/questions/499185/is-san-storage-better-than-nfs )
- AWS Direct Connect does not encrypt your traffic that is in transit by default. But the connection is private (https://docs.aws.amazon.com/directconnect/latest/UserGuide/encryption-in-transit.html)
