A finance company is migrating its trading platform to AWS. The trading platform processes a high volume of market data and processes stock trades. The company needs to establish a consistent, low-latency network connection from its on-premises data center to AWS.

The company will host resources in a VPC. The solution must not use the public internet.

Which solution will meet these requirements?

A.

Use AWS Client VPN to connect the on-premises data center to AWS.

Answers
A.

Use AWS Client VPN to connect the on-premises data center to AWS.

B.

Use AWS Direct Connect to set up a connection from the on-premises data center to AWS

Answers
B.

Use AWS Direct Connect to set up a connection from the on-premises data center to AWS

C.

Use AWS PrivateLink to set up a connection from the on-premises data center to AWS.

Answers
C.

Use AWS PrivateLink to set up a connection from the on-premises data center to AWS.

D.

Use AWS Site-to-Site VPN to connect the on-premises data center to AWS.

Answers
D.

Use AWS Site-to-Site VPN to connect the on-premises data center to AWS.

Suggested answer: B

Explanation:

AWS Direct Connect is the best solution for establishing a consistent, low-latency connection from an on-premises data center to AWS without using the public internet. Direct Connect offers dedicated, high-throughput, and low-latency network connections, which are ideal for performance-sensitive applications like a trading platform that processes high volumes of market data and stock trades.

Direct Connect provides a private connection to your AWS VPC, ensuring that data doesn't traverse the public internet, which enhances both security and performance consistency.

AWS

Reference:

AWS Direct Connect provides a dedicated network connection to AWS services with consistent, low-latency performance.

Best Practices for High Performance on AWS for performance-sensitive workloads like trading platforms.

Why the other options are incorrect:

A . AWS Client VPN: While this offers secure connectivity, it's over the public internet and is not designed for the low-latency, high-performance needs of a trading platform.

C . AWS PrivateLink: PrivateLink is used for connecting VPCs and services within AWS, but it is not designed for connecting on-premises data centers to AWS.

D . AWS Site-to-Site VPN: Although this provides secure connectivity, it uses the public internet, which can introduce latency and doesn't meet the low-latency requirements of the use case.
