Lesson 6: Hands-on Labs for VPC


Welcome to Lesson 6 of our "Fundamentals of AWS" series! In this module, we take a hands-on approach to reinforce the networking fundamentals covered earlier. Get ready to dive into practical exercises designed to enhance your proficiency in Virtual Private Cloud (VPC) configuration and troubleshooting. Let's roll up our sleeves and embark on a journey through essential VPC labs!



Our objectives for this lesson are clear:


1. Apply Knowledge through Practical Exercises:

   - Gain hands-on experience in creating and configuring VPCs.

   - Establish VPC peering connections, configure NAT gateways, and work with security groups and network access control lists (NACLs).


2. Gain Proficiency in VPC Configuration and Troubleshooting:

   - Develop practical skills for real-world VPC scenarios.

   - Learn to troubleshoot common VPC-related issues.


 1. Lab 1: VPC Creation:

 Hands-On Experience in Creating a VPC with Multiple Subnets:


   Step 1: VPC Setup:

     - Use the AWS Management Console to create a VPC.

     - Define the IP address range, subnets, and route tables.


   Step 2: Subnet Configuration:

     - Create public and private subnets in different availability zones.

     - Configure route tables for internet access.


   Step 3: Instance Deployment:

     - Launch instances in both public and private subnets.

     - Test connectivity between instances.


Participants will execute these steps in a controlled environment, gaining practical insights into VPC creation.


 2. Lab 2: VPC Peering:

 Establishing VPC Peering Connections between Two VPCs:

   Step 1: VPC Peering Setup:

     - Use the AWS Management Console or AWS CLI to create VPC peering connections.

     - Accept and configure peering between VPCs.


   Step 2: Testing Connectivity:

     - Deploy instances in both peered VPCs.

     - Verify seamless communication between instances across VPCs.


Participants will witness the power of VPC peering in action, enhancing their understanding of interconnected cloud environments.


 3. Lab 3: NAT Configuration:

 Configuring NAT Gateways for Instances in Private Subnets:

   Step 1: NAT Gateway Setup:

     - Create and configure NAT gateways for instances in private subnets.

     - Associate Elastic IP addresses for outbound internet access.


   Step 2: Private Subnet Instances:

     - Deploy instances in private subnets.

     - Test internet connectivity through NAT gateways.


Participants will gain hands-on experience configuring NAT gateways, a crucial aspect of enabling internet access for private instances.


 4. Lab 4: Security Groups and NACLs:

 Configuring Security Groups and Network Access Control Lists:

   Step 1: Security Groups:

     - Define security groups for instances with specific inbound and outbound rules.

     - Apply security group rules for fine-grained control.


   Step 2: NACL Configuration:

     - Create network access control lists with custom rules.

     - Test traffic filtering and evaluate the impact on instance connectivity.


Participants will become adept at securing their VPC environments using security groups and NACLs, ensuring a robust and controlled network.


 Example: Participants will perform the labs in a sandbox environment provided by AWS, reinforcing concepts through practical application.


AWS provides a dedicated sandbox environment for each participant, ensuring a safe space for exploration without impacting production environments. This example ensures a real-world, hands-on learning experience, allowing participants to solidify their understanding of VPC concepts.


In conclusion, hands-on labs are a cornerstone in the journey to mastering AWS VPC. By actively engaging with the platform, participants can translate theoretical knowledge into practical skills. Stay tuned for more AWS insights and hands-on experiences in our upcoming lessons!
