AWS VPC Networking: Managing Elastic IPs and Public Addressing

Maintaining stable public entry points for your cloud infrastructure is critical for reliable application delivery. This text-only course guides you through the fundamentals of AWS Elastic IPs and VPC networking, helping you establish persistent public addresses that survive instance restarts. You will gain a solid understanding of how public IP addressing works within a Virtual Private Cloud (VPC). You will learn how to allocate, associate, and release Elastic IPs, configure them for high availability, and implement cost-optimization strategies to avoid unnecessary charges under modern cloud pricing models. What you'll learn: - Understand the core differences between static, dynamic, and Elastic IP addresses in AWS - Allocate and associate Elastic IPs to EC2 instances and Network Load Balancers - Configure NAT Gateways to enable secure outbound internet access for private subnets - Implement cost-saving strategies to avoid idle IP charges under current cloud pricing rules - Explore modern IPv6 dual-stack configurations alongside traditional IPv4 addressing - Troubleshoot common VPC routing and public connectivity issues through written walkthroughs Starting with foundational networking definitions, this course walks you through the step-by-step logic of AWS internet gateways, route tables, and address allocation. You will progress from basic IP associations to advanced architectural patterns, including high availability and modern IP address management. This course is designed for beginning cloud administrators, systems engineers, and developers looking to master AWS networking basics. No prior cloud networking experience is required, though a basic familiarity with cloud concepts is helpful.
