A regional building-department portal must keep database latency low for local staff while surviving an Availability Zone outage, and later may serve a second metro Region for DR locality. How should the architect place the database tier for performance and HA?
Select an answer to reveal the explanation.
Short Explanation
Put the records desk next to the clerks who use it, then give that desk a twin in another fire zone. Multi-AZ covers the building fire; another Region covers the metro disaster—without shipping every click across the country for no reason.
Full Explanation
High-performing database design places the primary close to the application tier to reduce latency while using Multi-AZ deployments for Availability Zone resilience. Multi-Region read replicas or regional stacks address locality and disaster recovery across metros when required. Single remote Region placement, disabling Multi-AZ, or laptop-hosted copies undermine either latency, HA, or both.
