Dynamics AX Public Cloud is available – in normal English that’s Dynamics AX built on and for Microsoft Azure as a cloud ERP service. This site (http://bit.ly/1Rfz2fL) gives you an overview of the licensing options – it’s USLs (as you’d expect) and DSLs (as you might not) and for the USLs there are different levels available dependent on what the user needs to do.
For those who love an overview there’s a useful Quick Reference Guide available on this site, and for those made of sterner stuff there’s a full 28-page Licensing, Pricing and Support Guide.
