VPC NETWORKING FUNDAMENTAL

Introduction

In the pre-cloud computing era, establishing a network infrastructure required a plethora of hardware components, including Switches, Routers, Internet cables and RJ-45 connectors. These physical components enabled computers to communicate with each other and access the internet. Fast-forward to the cloud computing era, where virtualization has revolutionized networking. With Virtual Private Cloud (VPC), you can create a secure, isolated network environment without the need for physical hardware.

In this guide, I will walk you through the step-by-step process of creating a Virtual Private Cloud(VPC), including setting up Public and private subnets, Internet Gateway, Network ACLs (Access Control Lists) and Security Groups. By the end of this guide, you will have a fully functional VPC network, secure and ready for your applications.

Next, let's create our NAT gateways for the private subnets.

NAT GATEWAYS

ROUTE TABLES

Now that we have our subnets and NAT gateways setup, let's create route tables to define traffic routing rules.

PUBLIC ROUTE TABLES

PRIVATE ROUTE TABLES

EC2 And Security Groups

Now that we have our VPC, subnets, route tables, and NACLs configured, let's create EC2 instances and security groups to direct traffic.

Now that we've updated the security group inbound rules to allow traffic on port 8000, you can access your application.

Congratulations, we have successfully designed and implemented a secure and scalable Virtual Private Cloud (VPC) architecture.
