Which solution will meet these requirements?
Create a gateway VPC endpoint for each S3 bucket. Attach the gateway VPC endpoints to each subnet inside the VPC.
Create an interface VPC endpoint for each S3 bucket. Attach the interface VPC endpoints to each subnet inside the VPC.
Create one gateway VPC endpoint for all the S3 buckets. Add the gateway VPC endpoint to the VPC route table.
Create one interface VPC endpoint for all the S3 buckets. Add the interface VPC endpoint to the VPC route table.
Explanations:
Creating a gateway VPC endpoint for each S3 bucket is not necessary since a single gateway VPC endpoint can serve multiple S3 buckets within the same AWS region, leading to unnecessary management overhead and potential misconfiguration.
Interface VPC endpoints are used for connecting to AWS services that are accessed via private IP addresses, but S3 uses gateway endpoints instead. Additionally, creating an interface VPC endpoint for each S3 bucket would incur additional costs, which the company wants to avoid.
Creating one gateway VPC endpoint for all S3 buckets allows secure access over a private connection without additional costs. The gateway VPC endpoint can be added to the VPC route table, enabling all EC2 instances in the VPC to access the S3 buckets privately.
An interface VPC endpoint is not the correct choice for S3 access, as S3 uses gateway endpoints. Furthermore, creating one interface VPC endpoint would also incur additional costs, contrary to the company’s requirements.
As I see it, the answer is:
Create one gateway VPC endpoint for all the S3 buckets. Add the gateway VPC endpoint to the VPC route table.
