RemoteApp -- codenamed "Mohoro," which is currently in preview -- isn't a streaming service like other desktop-as-a-service offerings. Instead, it allows users to remotely access line-of-business apps, including Microsoft's Office desktop apps, on their mobile devices. The final version of the RemoteApp service will be available before the end of calendar 2014, officials have said.
"The desktop apps you publish through the Azure RemoteApp service, including Office and additional LOB apps can now be accessed from Windows RT devices where they otherwise can’t be installed. While the RemoteApp programs will appear to run locally, they are actually running in Azure and you can interact with them from your Windows RT device, helping keep your corporate data safe."
Instructions for installing the new Windows RT client for RemoteApp are available in the June 23 blog post.
