I am thinking of making my enterprise application available on Amazon Marketplace. This involves creating a Virtual Machine containing an encoded and licenced copy of the application. When a customer wishes to use this app Amazon will give them access to a cloned copy of this VM.
This means that the app on the VM must have a perpetual licence, but is there a way to prevent a VM from being run on a non-Amazon server? Or to prevent the software from being extracted from and run outside of the VM?
With the PRO Encoder you can create license files. Often these are used to lock to specific domains, but they can also contain arbitrary properties. You might create a property that stores the filepath and inode number of a file that you don't expect ever to change on the machine, then read those properties back at runtime via the Loader API and perform a check to ensure that file still exists and has the expected inode number. A cloned instance should always pass the test, but move the files to another machine and the test would also certainly fail unless the file system was replicated at the block device level. You might come up with some other creative ideas along similar lines. _________________ Community Admin
