The voting results API SLA requires survival of an availability-zone failure. How should resources be provisioned?
Select an answer to reveal the explanation.
Short Explanation
If one city block loses power, the results API still has to answer from another block. Multi-AZ placement is that second block—redundancy for the SLA, not a lone laptop.
Full Explanation
Availability requirements that tolerate AZ failure drive multi-AZ (or equivalent) redundant provisioning of compute, load balancing, and dependent services. Single-AZ designs, laptop bastions, and disabled health checks undermine that SLA.
