It doesn't happen often, but Microsoft will periodically release updated or new graphics to help build presentations and develop workflow and infrastructure documents. More so than not, we usually have to wait for a community member to develop their own and share with everyone. So, it's pretty great to see that Microsoft has taken the time to put together a symbol pack specifically for Windows Azure (and related technologies).
The download contains both symbol sets and PNG files. The icon/symbol pack supports Office Visio 2003 and PowerPoint 2007 or later. The PNG files can be used by those who don't currently have either Visio or PowerPoint, or would simply like to use the graphics elsewhere.
The download is here: Windows Azure Symbol/Icon Set
Included are almost 90 symbols and they all embody the very flat, mono-color schemes that Microsoft has adopted across the company's web site and modern applications.
