What is the VPC Endpoint and what is the difference between Interface Endpoint and Gateway Endpoint ?

VPC endpoint allows you to privately connect your VPC to supported AWS services and VPC endpoint services powered by?PrivateLink?without requiring an internet gateway, NAT device, VPN Connection, or AWS Direct Connect connection.

Instances in your VPC do not require public addresses to communicate with the resources in the service. Traffic between your VPC and the other service does not leave the Amazon network.

VPC Endpoints are horizontally scaled, redundant and highly available VPC components that allow communication between instances in your VPC and services without imposing availability risks or bandwidth constraints on your network traffic.

VPC Endpoints are virtual devices.

There are two types of VPC Endpoints

• Interface Endpoint

1. You got the Elastic Network Interface with a Private IP.
2. Interface Endpoint use DNS entries to redirect traffic.
3. Interface Endpoint used by the Services - API Gateway, CloudFormation, CloudWatch etc.
4. For Security Interface Endpoint use Security Group.

• Gateway Endpoint

1. A Gateway Endpoint you have a target for a specific route.
2. Gateway Endpoint uses prefixes lists in the route table to redirect traffic.
3. Amazon S3, DynamoDB use Gateway Endpoint
4. For the Security purpose Gateway Endpoint use VPC Endpoint Policies.
