Same dimensions, different formats
One of the things FinOps teaches us is the importance of reporting on and taking control of costs as soon as one starts operating in cloud. The first step in that process is to understand the content and dynamics of billing data and their correlation to FinOps capabilities, etc. Then use this information to equip FinOps Personas with means for informed decision making and managing the value of cloud.
This is no picnic even if you work with only one cloud provider. However, with the rising popularity of a multicloud strategy in organizations, things get more complicated with every new service provider that enters the mix. This is because each provider delivers the data in their own billing data formats with similar and yet specific cost and usage dimensions and metrics. Delivery formats, publishing frequencies, etc. also differ.
The lack of cost and usage and billing data standards across multiple service providers makes accommodating your cloud cost management process or solution to the growing number of service providers extremely difficult and time consuming. Many practitioners have been struggling with this issue for years.
