Q45Design Resilient Architectures
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** 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 provides the **MOST reliable** data transfer?

DMS is for databases and here refers to “JSON files”. Public internet is not reliable. So best option is B.
B 21
***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.

***WRONG***
Option A, AWS DataSync over the public internet, is not as reliable as using Direct Connect, as it can be subject to potential network issues or congestion.
Option C, AWS Database Migration Service (DMS) over the public internet, is not a suitable solution for transferring large amounts of data, as it is designed for migrating databases rather than transferring large amounts of data from a storage area network (SAN).
Option D, AWS DMS over AWS Direct Connect, is also not a suitable solution, as it is designed for migrating databases and may not be efficient for transferring large amounts of data from a SAN.

B 3
near-real-time + large data + secure = DataSync over DirectConnect
A: Less secure due to public internet
C: Slow and not secure
D: Slow even if more secure
DC may not even work as we don't know if there is a DB on other side but even if it was there, it is less preferred way
B 3
AWS DataSync is designed for large scale, high speed data transfer between on-prem and S3.
Using AWS Direct Connect provides a dedicated, private connection for reliable, consistent data transfer.
DataSync seamlessly handles data replication, encryption, recovery etc.
B 3
Secure and Most reliable transfer = AWS DataSync over AWS Direct Connect
B 3
DataSync is a service specifically designed for data transfer and synchronization between on-premises storage systems and AWS storage services like S3. It provides reliable and efficient data transfer capabilities, ensuring the secure movement of large volumes of data.
By leveraging Direct Connect, which establishes a dedicated network connection between the on-premises data center and AWS, the data transfer is conducted over a private and dedicated network link. This approach offers increased reliability, lower latency, and consistent network performance compared to transferring data over the public internet.
Database Migration Service is primarily focused on database migration and replication, and it may not be the most appropriate tool for general-purpose data transfer like JSON files.
Transferring data over the public internet may introduce potential security risks and performance variability due to factors like network congestion, latency, and potential interruptions.

explanation about D option is good
2
Any DMS related-service will not be efficient because DMS can only process JSON files UPTO 2 MB in size

so B is CORRECT
B 2
Public internet options automatically out being best-effort. DMS is for database migration service and here they have to just transfer the data to S3. Hence B.
B 2
Ans B - keep it simple... private netwk + direct connection
B 1
AWS DataSync supports Encryption and Compression and it is much more safer over a Direct Connect.
B 1
Option B
1
B is correct
1
Best option and correct is B
1
Not over public hence AC out / DMS is for databases and here refers to “JSON files”.
B 1
Option B. DMS is not needed as there is no Database migration requirement.
B 1
as Ariel suggested and rightly so.....DMS is for databases and here refers to “JSON files”. Public internet is not reliable. so B
