A permit application's chatty app tier and database generate large cross-AZ data-transfer charges inside one Region. Which cost-aware placement approach is most appropriate while retaining HA?
Select an answer to reveal the explanation.
Short Explanation
Chatty neighbors should live on the same block, with a spare house on the next block for HA. Cut pointless cross-AZ chatter without abandoning Multi-AZ design.
Full Explanation
Cross-AZ data transfer has a cost, so architects should place chatty components carefully—often keeping primary conversations local while still spanning AZs for high availability. Moving to more Regions increases transfer cost. Collapsing to a single host removes HA. Hairpinning via the public internet worsens security and usually cost.
