Software Licensing Challenges

Delivering physical goods can be a challenge such as hardware keys. Having IT departments wait 2-3 days to get a security key can be troublesome.  Accessing office networks during a pandemic can be unreliable.

Advantages of Cloud Licensing

Cloud licensing has many advantages such as one identity of user, only one license will work at a time if they have installed on many machines which helps eliminate the need to activate the license on multiple devices; and thus helps eliminate piracy. It is also more secure and reliable.

For Independent software providers (ISVS), it also eliminates the need for shipping physical keys.

For Customers:  Using the product reliably when accessing their office network is a challenge, this helps eliminate the need to collect physical keys.

LDK with EMS:  Can sell the cloud service along with EMS so it reduces the need for IT departments to maintain servers or to get to the office. Being able to grand licenses through the cloud allows the product to be easier to use, consume, and be more reliable with this model of licensing.
