VPC Endpoints (AWS PrivateLink)

Every AWS service is publicly exposed (public URL)
VPC Endpoints (powered by AWS PrivateLink) allow you to connect AWS services using a private network instead of using the public internet
They are redundant and scale horizontally
They remove the need for IGW, NATGW, etc. to access AWS services
In case of issues:
- Check DNS Setting Resolution in our VPC
- Check the Route Tables
Types of Endpoints
- Interface Endpoints
  - Provisions an ENI (private IP address) as an entry point (must attach to a Security Group)
  - Supports most AWS services
- Gateway Endpoints
  - Provisions a gateway and must be used as a target in a route table
  - Supports both S3 and DynamoDB
