Microsoft annouced yesterday that Azure AD Connect is now generally available. AADConnect allows you to quickly onboard to Azure AD and Office 365.
You can download it here - https://www.microsoft.com/en-us/download/details.aspx?id=47594
I'm currently working on a version of my PowerShell MA that will work with AADConnect as I think this will make for a interesting way to do more with AADConnect than just synchronize to Azure AD.
Stay tuned here for more on that.
