One of the things that I've been busy with lately is reviewing a series of upcoming whitepapers from Microsoft.
The SQLCAT team today launched one of those whitepapers. It's a performance guide for SQL Server when working with Azure VMs (Virtual Machines).
It's great to see that it's been released and you'll find it here: http://sqlcat.com/sqlcat/b/whitepapers/archive/2013/05/31/performance-guidance-for-sql-server-in-windows-azure-virtual-machines.aspx
There's more to working with SQL Server in Azure than just putting it onto a VM. It's great to see much of this now documented.
