Our friends at Microsoft have helped us information architects out with some official Visio shapes for SharePoint. IT Pros and Farm Admins certainly will benefit as well.
Creating visual representations of your Microsoft Office and Office 365 architectures, including Microsoft Exchange, SharePoint, and Skype for Business is a helpful way to communicate your deployment. These Visio stencils provide more than 300 icons -- many depicting servers, server roles, services and applications -- that you can use in architecture diagrams, charts, and posters. These icons are primarily centered around deployments of Microsoft Exchange Server 2013, Microsoft Skype for Business, and Microsoft SharePoint Server 2013 as well as hybrid Office 365 deployments of aforementioned technologies.
The zip file now includes both stencil sets from 2012 and 2014.
