Overview

This lab will guide you through creating a VPC and implementing network segmentation. By the end of the exercise, your VPC will include 2 public subnets and 2 private subnets.

1 Setup VPC

1-a. Open the AWS Management Console and go to the VPC section.

1-b. Under Your VPCs, click Create VPC.

1-c. Specify a /16 CIDR block for the VPC. Ensure it doesn’t overlap with any existing VPCs. Optionally, include your name in the VPC name for easy identification.

1-d. Your VPC has been successfully created.

2. Set Up Private Subnets

2-a. Go to Subnets and click Create Subnet.

2-b. Create a private subnet:

  • Choose your VPC.
  • Name the subnet "Private Subnet A."
  • Assign it a /24 CIDR block.
  • Pick an Availability Zone (AZ).

2-c. Your private subnet has been created.

2-d. Create another private subnet:

  • Name it Private Subnet B.
  • Assign it a different /24 CIDR block.
  • Select an AZ different from Private Subnet A.
  • You now have two private subnets.

3. Setup an Internet Gateway

3-a. To enable internet connectivity for public subnets, first create an Internet Gateway (IGW). Go to Internet Gateway and click Create Internet Gateway.

3-b. Name your Internet Gateway and click Create.

3-c. Attach the IGW to your VPC:

  • Select the IGW.
  • Click Actions, then Attach to VPC.

  • Choose your VPC and confirm the attachment.

4. Set Up Public Subnets

4-a. Create two public subnets:

  • Name them Public Subnet A and Public Subnet B.
  • Assign both a /24 CIDR block.
  • Ensure each is in a separate AZ.

4-b. Create a Route Table for the public subnets:

  • Go to Route Tables and click Create Route Table.

  • Name it and associate it with your VPC.

4-c. Update the routes for the public route table:

  • Select the route table and go to the Routes tab.
  • Click the Edit Routes button.

  • Add a route with:
  • Destination: 0.0.0.0/0
  • Target: Your Internet Gateway.
  • Save the changes.

4-d. Associate the public subnets with the route table:

  • Go to the Subnet Associations tab in the route table.
  • Click Edit Subnet Associations and select your public subnets.

  • Save the associations.

5. Set Up a Route Table for Private Subnets

5-a. Create a route table for the private subnets:

  • Name it and associate it with your VPC.
  • You don’t need to edit routes for the private route table.

5-b. Associate the private subnets with this route table by editing the Subnet Associations.

Lab Completion

  • Congratulations! You’ve completed the lab.
