What counts as billable data transfer? It is apparently data that transfers out of the data centre but what is that exactly?
If a SQL Azure database is queried by a web role in the same region is the data going from the SQL Azure database to the web role billed for?
Is data from a same region storage account to a web role billed? If so what about in the same affinity group?
Is bandwidth from the web role itself down to the user billed? E.g. images stored as part of the solution being viewed by lots of people.
Is the data transferred during a remote desktop session billed? I.e. literally the bandwidth used to actually see an instance’s desktop via RDP, not anything downloaded from that instance.
No. This transfer will not be billed. But only if the region is specific (i.e. North Europe, but not Anywhere Europe). The data stays within the same data center.
No. This transfer is not billed. Again meaning specific Region, and not Generic region (anywhere **). As for Hosted Service and Storage Account in same affinity group – it will also not be billed. The data stays within the same Data Center.
Yes. This is Out transfer which is being billed. The data is going out of the Data Center.
Yes, this transfer will be billed. But only the outbound traffic. You know that RDP session is two way communication. Only the part which is outward the Data Center will be billed, not the inbound traffic. There is data traffic (TCP packets) going out of the data center.
