An organization is deploying a high-traffic database application on Azure Virtual Machines. The engineering team requires predictable performance with guaranteed input/output operations per second (IOPS) and throughput to maintain consistent service levels across varying workloads.
Which Azure feature should the team configure to ensure predictable storage performance and resource allocation without causing downtime?

Performance tiers in Azure determine the provisioned IOPS (Input/Output Operations Per Second) and throughput available to Azure managed disks (such as Premium SSDs). When a disk is provisioned, a baseline performance tier is assigned according to the disk capacity, ensuring dedicated performance baselines for compute and storage workloads.
By utilizing performance tiers, administrators can explicitly adjust and allocate disk processing bandwidth and transaction capacity without resizing the physical disk or introducing service interruptions:
Cloud performance predictability relies on dedicated, consistent resource guarantees. Configuring disk performance tiers allows direct control over storage execution speeds and throughput caps, directly fulfilling SLA performance commitments without impacting system availability.
