How Azure Pricing Works
Understand the factors that affect Azure costs — resource type, tier, location, and consumption — and compare pay-as-you-go with reserved and spot pricing models.
Azure's Consumption-Based Pricing Model
Azure uses a pay-as-you-go (PAYG) pricing model: you pay only for the cloud resources you consume, with no upfront capital commitment and no minimum term. This is called OpEx (operational expenditure) as opposed to the traditional CapEx (capital expenditure) model of buying and owning servers. You are billed monthly based on your actual metered resource usage.
Key Factors That Affect Azure Cost
Azure resource costs are determined by several factors. Resource type and configuration — a 64-core VM costs far more than a 2-core VM. Region — prices vary by Azure region due to local energy, labour, and datacentre costs. Bandwidth — inbound data transfer to Azure is generally free; outbound transfer is charged per GB. Consumption level — some services like Azure Functions charge per execution; others like VMs charge per hour of uptime.
