Azure VM costs can escalate quickly without proper management. Understanding pricing models and leveraging cost-saving features can reduce your monthly cloud spend by 30-60% without sacrificing performance or availability.
Reserved Instances and Spot VMs
Azure Reserved VM Instances offer up to 72% savings compared to pay-as-go pricing in exchange for a one- or three-year commitment. Analyze your stable baseline workloads to identify candidates for reservations, and use pay-as-you-go for variable demand.
Azure Spot VMs provide access to unused compute capacity at steep discounts, ideal for batch processing, development environments, and fault-tolerant workloads. Implement checkpointing in your applications to handle eviction gracefully.
Right-sizing your VMs is equally important. Use Azure Advisor recommendations and monitor actual CPU, memory, and disk utilization. Many organizations discover that their VMs are significantly over-provisioned, wasting budget on unused capacity.
