Question

A company runs a stateless web tier on three Azure VMs in a single region. The application must remain available during a datacenter-level hardware failure or power loss, and the design must achieve the highest available compute SLA offered by Azure for VMs. The workload is not latency-sensitive across zones. Which deployment approach should you recommend?
