VPC Endpoints

Introduction to VPC endpoints

We already know that connecting to AWS public services, such as S3, SNS, and so on, requires connectivity to the public internet. We may use either the internet gateway alone or in conjunction with the NAT gateway to allow our subnet resources to reach the internet.

What if our VPC resources don’t have internet access but need to connect with other AWS services? AWS provides a service called VPC endpoints to accomplish this.

VPC endpoints enable private connectivity from an Amazon VPC to AWS public services and other supported AWS services without the need for an internet gateway, NAT gateway, or VPN connection.
