A small township VPC has private-subnet workloads that need occasional outbound internet access. Leadership wants to limit NAT cost while understanding HA trade-offs. Which guidance is most accurate?
Select an answer to reveal the explanation.
Short Explanation
One shared town pump is cheaper than a pump on every block—but if that pump's street floods, everyone is dry. Shared NAT saves cash; per-AZ NAT buys isolation.
Full Explanation
A single NAT Gateway reduces hourly and often data-processing cost for small environments but creates an AZ dependency. Per-AZ NAT Gateways improve high availability at higher cost. Assigning public IPs to private-subnet instances undermines the private design. Snowmobile is for exabyte migration, not routine patch egress.
