Trying out and demonstrating the Dynamics AX 2012 R3 companions apps just became a lot easier using Lifecycle Services for Dynamics AX to deploy AX 2012 R3 VMs on Azure.
1. As a first step, LCS makes it very easy to deploy an Azure-based VM with AX 2012 R3 already installed. Details are here http://technet.microsoft.com/en-us/library/dn741581.aspx
2. Then simply follow the config steps to connect the AX phone and tablet apps to your AX VM in Azure: https://mbs.microsoft.com/files/customer/AX/Downloads/Servicepacks/HowtoConnectMobileAppsNAXinAzurePartner.pdf
Now you'll have a trial / demo environment (accessible from anywhere) that you can tweak and use to explore the apps. You can turn the VM on or off as needed.
Give it a try and we look forward to hearing your feedback!
