Overview

This video is a technical class session focused on setting up and troubleshooting Virtual Private Cloud (VPC) and Elastic Compute Cloud (EC2) instances in AWS. The session covers the creation of VPCs, subnets, security groups, and EC2 instances, including detailed explanations of networking concepts like CIDR blocks, public vs. private subnets, and inbound/outbound rules. It also touches upon Linux commands, resource management, and common troubleshooting scenarios encountered during AWS deployments.

Key takeaways

• VPC and Subnet Configuration: The class demonstrates the process of creating a VPC with a specific CIDR block (10.10.0.0/16) and configuring multiple public and private subnets across availability zones, emphasizing the importance of distinct IP ranges for segmentation.
• Security Group Management: Setting up both public and private security groups is crucial. Public security groups allow broader access (e.g., HTTP, SSH, ICMP), while private security groups have more restricted inbound rules, often allowing traffic only from within the VPC. Granularity in security group rules is emphasized for security and manageability.
• EC2 Instance Deployment: The session details the steps for launching both public and private EC2 instances, including selecting appropriate AMIs, instance types, key pairs, and crucially, associating them with the correct VPC, subnets, and security groups.
• Troubleshooting Common Issues: Several troubleshooting scenarios are addressed, including issues with accessing web pages due to incorrect security group rules (especially missing HTTP or incorrect source IPs), problems with instance connectivity, and the importance of ensuring the script for user data runs correctly.
• Resource Teardown: The importance of a systematic teardown process is highlighted, involving terminating instances, releasing Elastic IPs, and deleting NAT gateways and VPCs to avoid ongoing charges and maintain a clean environment.
