BGP Routing, Private Networking, Encryption, Anycast, and Application Deployment Across Data Centers

This chapter covers various networking topics such as BGP routing decisions based on cost, the advantages of Fly.io's private networking approach, handling encryption with WireGuard, using Anycast for efficient global routing, and deploying applications across multiple data centers with automatic TLS termination. The speakers discuss challenges with application instances, state maintenance, and data synchronization, using examples like managing webhooks from Patreon. The conversation also humorously touches on how requests are distributed among instances, including references to TCP sessions and goat teleportation.
