Question

A transit-authority analytics VPC routes all private-subnet egress through a single undersized NAT instance that saturates during evening GTFS feed pulls, throttling job completion. Which network-path remediation best improves throughput?

Accepted Answer

Replace the undersized single NAT path with appropriately sized NAT Gateway capacity (or scaled NAT design) and multi-AZ egress so concurrent feed downloads are not pinned to one bottleneck host — One skinny doorway for every evening feed download is a classic traffic jam. Upsize and spread the NAT egress path so the buses of data are not stuck behind one turnstile.

Answer

Move all analytics workers into the public subnet with open 0.0.0.0/0 security groups and no egress control

Answer

Disable VPC Flow Logs to increase available bandwidth on the NAT instance

Answer

Force all GTFS pulls through a single-threaded on-premises HTTP proxy that already times out
