The document discusses different strategies for licensing CRM solutions and cloud services. It covers challenges with licensing, such as preventing unauthorized use while not punishing legitimate customers. It then describes strategies like using license keys tied to specific deployments and implementing public key cryptography. The document demonstrates how to generate and validate licenses. It also proposes using a "license wall" approach of putting solutions behind a check that authenticated customers can access online resources. The "license wall" is discussed as an easier alternative to generating license keys that avoids maintenance while allowing for subscription or user-based models.
