Explain the differences between Azure Availability Zones and Azure Availability Sets. Scope: Availability Zones offer fault isolation at a geographic level by distributing resources across separate data centers. Availability Sets provide fault tolerance within a single data center. Number of Zones/Sets: Availability Zones consist of at least three zones per region, while Availability Sets are limited to a single data center within a region. Protection against Failures: Availability Zones protect against data center-level failures, ensuring high resilience. Availability Sets protect against rack-level failures within a data center.
