Designing Custom VPCs and CIDR Blocks in AWS Networking

Every robust cloud deployment relies on a solid network foundation, yet setting up custom Virtual Private Clouds (VPCs) can feel overwhelming. Understanding how IP addressing, subnetting, and routing work is essential to building secure and scalable cloud infrastructure. This text-based course guides you through the foundational principles of cloud networking, helping you transition from basic IP concepts to confidently planning, designing, and documenting custom VPC topologies. What you'll learn: - Understand the core concepts of IP addressing, CIDR notation, and subnet division within a cloud environment. - Design custom VPCs from scratch, ensuring proper IP allocation to avoid overlapping networks. - Configure public and private subnets, route tables, and internet gateways for secure traffic flow. - Implement high-availability strategies across multiple Availability Zones using structured subnetting. - Apply modern security practices using Security Groups, Network Access Control Lists (NACLs), and VPC Flow Logs for traffic monitoring. - Explore modern cloud networking trends, including IPv6 integration basics and secure hybrid connectivity patterns. You will begin by learning fundamental networking terminology and CIDR math before moving step-by-step through the process of structuring subnets, establishing routing, and securing your custom cloud environment. This course is designed for aspiring cloud engineers, system administrators, and beginners looking to establish a strong grasp of cloud networking with no prior infrastructure experience required.
