My current understanding of Azure for websites is that it is using a virtual drive which allows a website to save files to the file system in the same way a classic server setup would do.
The question is however if this virtual drive is mirrored across different locations and what happens if the website instance scales. Is the drive scales as well? Are all files saved to that drive replicated across instances? Are all instances reading from the same drive?
While it is quite obvious that it should do some of the above as cloud hosting, I cannot find any documentation on the same.
Any links would be appreciated.
