Episode notes
Share Concrete Network Context
- Collaborate: have networking and developer teams share source and destination details when troubleshooting.
- Provide concrete network context (IPs, routes) to reduce friction and speed debugging.
Scale Multiplies Network Complexity
- Multi-account and multi-region architectures massively increase connectivity complexity.
- Designers must plan connectivity, performance, and governance across thousands of accounts and regions.
Design Around Destinations, Not Hosts
- Map your VPC as a bounded private network and use route tables to control destinations.
- Think in terms of where workloads must reach, not just IPs, to design routes and security.
