Codeigniter and Windows Azure

[eluser]Unknown[/eluser]
I have a web application built in CI, I need to migrate it to Windows Azure, and have the following questions:


1) How can I access the blob storage within my application? Does CI have support for this. If so, what is it?
2) I am using the old MSSQL drivers and not SQLSRV drivers. Do I need up upgrade - my application seems to break when I make the change.

Thanks.
