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.
