How to Create Virtual Private Cloud (VPC) with AWS CloudFormation

Lab Details

1. This lab walks you through how to create a VPC using an AWS CloudFormation Stack. In this lab, we will launch an AWS CloudFormation template to create a four-subnet Amazon VPC that spans two Availability Zones and a NAT that allows servers in the private subnets to communicate with the Internet in order to download packages and updates.

2. Duration: 55 minutes

3. AWS Region: US East (N. Virginia)

Introduction to AWS VPCs 

A VPC is similar to a computer network that we can create in an on-premises data center. In the same way, as we create dedicated and private networks within an organization, where computers in a network share network devices such as routers, switches, and so on, we can create a VPC when we create a new account in AWS.

VPC makes it possible to shape similar network infrastructure as we can shape it in our own data center. The difference is, it is a virtual environment within a public cloud wherein the virtual network is logically isolated from other similar networks within the public cloud.

Subnet: Subnet is short for the subnetwork. As we saw at the beginning of this chapter, a network is subdivided into multiple logical parts for controlling access to individual logical subparts of the network
