What is a VPC endpoint?

Services inside and outside the VPC

EC2 instances are a service within the VPC, while S3 is a service outside the VPC as it is located in a region.

VPC endpoints allow services inside the VPC to connect to AWS services outside the VPC without going through the Internet.

Secure communication is possible because it does not involve the Internet.

VPC endpoints have two types of connection formats
