With Azure Cost Analysis, it is easy to see costs of resources. Also Azure Cost Analysis data can be exported to Azure Storage as scheduled.
This repo is a demostration for the Azure Function which is triggered by BLOB Storage. The function takes the cost data from BLOB storage, processes the data and then sends the results as an e-mail.
This is just for some simple scenarios such as; proccess the cost data, share the cost information, follow-up the usage...etc.
Beside this simple implementation, there is also some other options to touch costs in Azure;
might work for you for more sophisticated scenarios. But these options are kind of a preview state and changes a lot and they are not so reliable so far. At least, they did not make me feel safe 😀
