Question 1

What is Amazon VPC?

Amazon Virtual Private Cloud (Amazon VPC)

Answer 1

A networking service that you can use to establish boundaries around your AWS resources is Amazon Virtual Private Cloud (Amazon VPC).

Amazon VPC enables you to provision an isolated section of the AWS Cloud. In this isolated section, you can launch resources in a virtual network that you define. Within a virtual private cloud (VPC), you can organize your resources into subnets. A subnet is a section of a VPC that can contain resources such as Amazon EC2 instances.

Question 2

What is Internet gateway?

Answer 2

An internet gateway is a connection between a VPC and the internet. You can think of an internet gateway as being similar to a doorway that customers use to enter the coffee shop. Without an internet gateway, no one can access the resources within your VPC.

Question 3

What is Virtual private gateway?

Answer 3

To access private resources in a VPC, you can use a virtual private gateway.

The virtual private gateway is the component that allows protected internet traffic to enter into the VPC. Even though your connection to the coffee shop has extra protection, traffic jams are possible because you’re using the same road as other customers.
