Securely Connect EC2 Instances to S3 Buckets via Private Network

Accessing Amazon S3 privately enhances security, improves performance, reduces costs, ensures compliance with regulatory requirements, simplifies network architecture, and provides reliable and managed connectivity. This approach is particularly beneficial for workloads that require secure, high-performance, and cost-effective access to S3

To connect to an S3 bucket privately from an instance in a private subnet, you can use AWS Private Link or a VPC endpoint for S3. This allows the traffic between your VPC and S3 to remain within the AWS network, avoiding exposure to the public internet.

STEP 1: Create a basic VPC for your use case :

STEP 2: Create a public and private subnet, in the above created VPC.
