A Step-by-Step Guide to Creating a Custom VPC on AWS - Day 29

Hello Readers! Welcome back to our #100DaysOfAWS journey. On Day 29, we're rolling up our sleeves to do some hands-on work - it's time to set up your very own custom Virtual Private Cloud (VPC) on AWS. Think of it as carving out your private oasis in the cloud. Today, I'll guide you through the process in simple, everyday language. So, let's get started!


Understanding the Need for a Custom VPC:

Before we dive into the setup, let's quickly understand why you might need a custom VPC. AWS gives you a default VPC, but creating a custom one offers more control. It's like having a plot of land where you decide the size, shape, and features of your AWS neighborhood.


Step 1: Accessing the AWS Management Console

  1. Login to AWS Console: First things first, log in to your AWS account. If you don't have one, go ahead and create it. Once in, head to the AWS Management Console.

Step 2: Navigating to VPC Dashboard

  1. Locate VPC in Services: In the AWS Management Console, find the "Services" dropdown. Scroll down or search for "VPC" and click on it. This is your gateway to the world of custom VPCs.

Step 3: Initiating Custom VPC Creation

  1. Click "Create VPC": Inside the VPC Dashboard, click on the "Create VPC" button. This is like laying the foundation for your new virtual home.

  2. Fill in Details: Now, it's time to name your VPC and assign an IPv4 CIDR block. Think of it as choosing the name and defining the borders of your virtual land.

Step 4: Configuring Subnets

  1. Navigate to Subnets: Once your VPC is created, go to the "Subnets" section. This is where you divide your land into smaller plots (subnets) for different purposes.

  2. Create Subnets: Click on "Create Subnet" and fill in the details. Specify the VPC, choose an availability zone, and assign an IPv4 CIDR block. It's like zoning your land for residential, commercial, or recreational use.

Step 5: Crafting Route Tables

  1. Go to Route Tables: Head to the "Route Tables" section in the VPC Dashboard. This is where you set the rules for traffic flow within your VPC.

  2. Create a Custom Route Table: Click on "Create Route Table" and name it. It's akin to designing the road signs and traffic rules for your VPC.

Step 6: Associating Subnets and Wrapping Up

  1. Associate Subnets: In the "Subnet Associations" tab of your custom route table, associate the subnets you've created. This is like linking specific streets to your custom traffic rules.

  2. Review and Create: Double-check your configurations, click "Create," and voila! You've successfully set up your custom VPC.

Creating a custom VPC matters because it gives you the power to shape your cloud environment. It's like building your dream home, complete with personalized spaces for different needs.


As we conclude Day 29, pat yourself on the back. You've just crafted your personal oasis in the AWS cloud. Stay tuned for more hands-on adventures in the upcoming days of our #100DaysOfAWS series. Until then, happy cloud learning!
