Beginners often know what a VPC, subnet, and security group are, yet stall the moment traffic won't flow. They are usually unsure where the break is. In this course, AWS Networking Fundamentals, you'll gain the ability to reason about and fix basic AWS connectivity.
First, you'll explore how VPCs, subnets, route tables, internet gateways, and security groups hand traffic off to one another.
Next, you'll discover how to build and verify a simple VPC connectivity pattern, confirming that intended traffic flows and unintended traffic is blocked.
Finally, you'll learn how to diagnose and correct the common misconfigurations behind failed connections.
When you're finished with this course, you'll have the skills and knowledge of foundational AWS networking needed to confidently move traffic through a simple AWS environment.
