In this chapter we learned to build a cost model that allows us to track costs in cloud and how these costs can be allocated to specific budgets. Key is the understanding that we must cover for all resources and services that an organization uses in cloud, including all shared resources.
We also saw that to get the right costing level, we must consider that we’re dealing with various types of rates. The rates that are shown in the pricing calculators of cloud providers, are often not applicable: discount programs might be applied, influencing the true costs of cloud environments. We learned about blended and unblended rates, managed and unmanaged services, direct and shared costs, consumption based and fixed costs. All of this must be reflected in the cost model to get to an accurate showback and eventually chargeback.
This was the final chapter about FinOps. The next part of this book will be about security.
