Your company is planning to move its files from its on-premises location onto S3
The services hosted in the on-premises environment would need low latency access to these files.
How can you achieve this?

A. B. C. D.Answer - B.
This is also given in the AWS Documentation.
To connect to AWS public endpoints, such as an Amazon Elastic Compute Cloud (Amazon EC2) or Amazon Simple Storage Service (Amazon S3), with dedicated network performance, use a public virtual interface.
Option A is invalid since VPN connections don't ensure low latency.
Option C is invalid since you need to have a Public VIF for public services such as S3.
Option D is invalid since VPC endpoints are invalid in this configuration.

https://aws.amazon.com/premiumsupport/knowledge-center/public-private-interface-dx/When moving files from an on-premises location to Amazon S3, it's important to ensure that services hosted in the on-premises environment have low-latency access to those files. Here are the options available to achieve this:
A. Create a VPN connection that would allow the services on-premises to access S3. This option involves setting up a VPN connection between the on-premises environment and the VPC hosting the S3 bucket. This allows the services in the on-premises environment to access the S3 bucket securely over an encrypted tunnel. However, this option may not provide the desired low-latency access to the S3 bucket, as the traffic would need to traverse the internet before reaching the S3 bucket.
B. Create a Direct Connect connection along with a Public VI. This option involves setting up a Direct Connect connection between the on-premises environment and the VPC hosting the S3 bucket, along with a public VIF (Virtual Interface). This allows the services in the on-premises environment to access the S3 bucket securely and with lower latency, as the traffic would be routed over the Direct Connect connection rather than the internet. However, the use of a public VIF may not be suitable for all scenarios, as it may increase the attack surface of the environment.
C. Create a Direct Connect connection along with a Private VI. This option is similar to option B, but instead of a public VIF, a private VIF is used. This provides additional security by ensuring that the traffic between the on-premises environment and the S3 bucket remains within the private network. This option is recommended for scenarios where security is a top priority.
D. Create a VPN connection along with a VPC endpoint. This option involves setting up a VPN connection between the on-premises environment and the VPC hosting the S3 bucket, along with a VPC endpoint for S3. This allows the services in the on-premises environment to access the S3 bucket securely over an encrypted tunnel, with lower latency as the traffic would not need to traverse the internet. The use of a VPC endpoint also provides additional security by ensuring that the traffic between the on-premises environment and the S3 bucket remains within the private network.
In summary, options B, C, and D are all viable solutions to achieve low-latency access to an S3 bucket from an on-premises environment. The choice between these options will depend on factors such as security requirements, network architecture, and performance considerations.
