Does S3 live in a VPC?

You can now access Amazon Simple Storage Service (Amazon S3) from your Amazon Virtual Private Cloud (Amazon VPC) using VPC endpoints. Amazon VPC endpoints are easy to configure and provide reliable connectivity to Amazon S3 without requiring an internet gateway or a Network Address Translation (NAT) instance.

What is NAT gateway?

A NAT gateway is a Network Address Translation (NAT) service. You can use a NAT gateway so that instances in a private subnet can connect to services outside your VPC but external services cannot initiate a connection with those instances.

What is gateway endpoint?

Gateway endpoints provide reliable connectivity to Amazon S3 and DynamoDB without requiring an internet gateway or a NAT device for your VPC. Gateway endpoints do not enable AWS PrivateLink. There is no additional charge for using gateway endpoints.

What is the difference between gateway and interface?

An interface endpoint is powered by PrivateLink, and uses an elastic network interface (ENI) as an entry point for traffic destined to the service. A gateway endpoint serves as a target for a route in your route table for traffic destined for the service.

What is a VPC endpoint?

A VPC endpoint is a virtual device which is horizontally scaled, redundant and highly available, that provides communication between EC2 instances within your Virtual Private Cloud and other supported AWS services without introducing availability risks or bandwidth constraints on your network traffic.

What are the two types of VPC endpoints?

When a connection times out, a NAT instance sends a FIN packet to resources behind the NAT instance to close the connection.

What ports do VPC endpoints use?

Network ACLs settings for VPC Endpoints
  • outbound: port=443, destination=
  • inbound: port=1024 – 65535, source=VPC-CIDR (ephemeral.

What is VPC routing?

In a VPC network, a route consists of a single destination prefix in CIDR format and a single next hop. When an instance in a VPC network sends a packet, Google Cloud delivers the packet to the route’s next hop if the packet’s destination address is within the route’s destination range.

What is VPC peering?

A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network.
