Pricing strategy is the method a cloud provider uses to charge for resource or service consumption. Azure pricing can depend on execution time, features, allocated capacity, region, and traffic, so a low sticker price is not the whole story. section 2.3.5 section 3.2.1
Use these questions when choosing a cloud resource:
- What is being metered: executions, compute time, used storage, allocated storage, or network traffic? section 2.3.5 section 5.4.1
- Which region offers an acceptable balance of price, performance, features, regulation, energy costs, and traffic charges? section 3.2.1
- Does a performance tier charge for what is used or for capacity reserved in advance? section 5.4.1
- How will usage and costs be calculated and monitored before an unexpectedly enthusiastic service becomes expensive? section 2.3.5 section 1.4
Image resizing
An image-resizing application assumes 100,000 Logic App executions, 100,000 Azure Function executions lasting 400 milliseconds, and up to 1,000 GB of Blob Storage. The estimated monthly total is $36.94: $15.80 for Logic Apps, no charge in the stated Function estimate, and $21.14 for Storage. section 2.3.5
