Ilok vs Ilok Cloud 

Definitely is!!!

@@jfreshbeatz_ There's also the most common option... iLok locked to OS/machine - no iLok device, no Cloud. It's just as carefree in the background as iLok Device, until you somehow modify your machine's signature with an OS reinstall or hardware modification. My preference for portability sake is iLok Device as the primary activation mode. Most products allow multiple activations for the same license, so I in those cases, I activate those to Cloud. If a third activation is available, I activate that to OS/machine. All has been running smooth and tranquil with the for-the-most-part invisible iLok Device, but there's comfort in knowing that for nearly all of my plugins and products, I'm still up and running without a hiccup if calamity strikes.
