Export

A company runs an application on Amazon EC2 Instances in a private subnet. The application needs to store and retrieve data in Amazon S3 buckets. According to regulatory requirements, the data must not travel across the public internet.

What should a solutions architect do to meet these requirements MOST cost-effectively?

A.
Deploy a NAT gateway to access the S3 buckets.
Answers
A.
Deploy a NAT gateway to access the S3 buckets.
B.
Deploy AWS Storage Gateway to access the S3 buckets.
Answers
B.
Deploy AWS Storage Gateway to access the S3 buckets.
C.
Deploy an S3 interface endpoint to access the S3 buckets.
Answers
C.
Deploy an S3 interface endpoint to access the S3 buckets.
D.
Deploy an S3 gateway endpoint to access the S3 buckets.
Answers
D.
Deploy an S3 gateway endpoint to access the S3 buckets.
Suggested answer: D

Explanation:

Understanding the Requirement: The application running in a private subnet needs to store and retrieve data from S3 without data traveling over the public internet.

Analysis of Options:

NAT Gateway: Allows private subnets to access the internet but incurs additional costs and still routes traffic through the public internet.

AWS Storage Gateway: Provides hybrid cloud storage solutions but is not the most cost-effective for direct S3 access from within the VPC.

S3 Interface Endpoint: Provides private access to S3 but is generally used for specific use cases where more granular control is required, which might be overkill and more expensive.

S3 Gateway Endpoint: Provides private, cost-effective access to S3 from within the VPC without routing traffic through the public internet.

Best Solution:

S3 Gateway Endpoint: This option meets the requirements for secure, private access to S3 from a private subnet most cost-effectively.
