Before March 2023, the author struggled to understand the complexity of the AWS VPC dashboard. They found the scrolling bar on the left-hand panel to be overwhelming. To gain a better grasp of the networking resources involved, they read the book “AWS Networking Fundamentals” by Toni Pasanen. After finishing it, they realized that the multitude of resources exists because there are various types of connections that can be established. These connections include AWS account to on-premise, account to account, VPC to VPC, subnet to subnet, VPC to internet, and VPC to specific AWS services. To help make sense of it all, the author created a mind map to connect all the pieces together. They invite feedback on its usefulness and any errors that may be present.
