[SPIKE] Supporting non USD currencies

[ericksod]

Context We would like this tool to be applicable and helpful to organizations and individuals across the globe. To do so, it is helpful to support international currencies.

A/Cs

• [ ] Investigate the following questions
• [ ] Perhaps consult a team we know operates in a different currency
• [ ] Document findings in the spikes folder

Questions to investigate

• [ ] Can we can retrieve billing data in different currencies?

• • [ ] How can we detect the currency coming back from billing data? Or utilize another API call for metadata?
• • [ ] Do each of the cloud providers support the same currencies?
• • [ ] Is billing data constrained to only one currency?
• • [ ] What support for currencies do we have with the recommendation APIs? Do we have to specify in request or does it default to set currency by account settings?
• • [ ] Error handling when a currency is unsupported by CCF

• [ ] How can we design this to be extended to various additional currencies?

• [ ] How would this impact API (high accuracy) approach - how much additional work if any would be needed to also support it here?

• [ ] How can we design this with future additional internationalization in mind?

• [ ] If cloud providers do not do the currency work for us, what options do we have for conversion?

• [ ] If change currencies, will data need to be backfilled?

I've got some screenshots from a Brazilian AWS account, it seems they keep the USD as the main currency and apply the exchange rate. We need to check if the API result is the same and/or we could do the same (apply the exchange rate) to show cost on our graphics in the local currency.
