AWS networking is the foundation for secure workload placement, private connectivity, segmentation, observability, and blast-radius control.

Topics

Reference Mindset

  • Know what is reachable over the network.
  • Know what is authorized by identity policy.
  • Treat network reachability and IAM authorization as separate control planes.
  • Prefer repeatable network patterns over one-off subnet and route table decisions.
  • Design for investigation: routing, logging, traffic metadata, and packet inspection all matter.
