When purchasing JFrog Products, depends on the subscription you purchased, you will either receive a license or bucket of licenses.
In case you have purchased a Pro, Pro X or Enterprise subscription, you will receive individual licenses that can be installed directly to the Artifactory node.
In case you have purchased the Enterprise subscription of 50+ servers or the Enterprise Plus subscription, you will receive bucket of licenses.
In this scenario, in order to install the licenses to your products (Artifactory, Edge-Nodes), the bucket of licenses, will first need to be added to Mission-Control which will install the licenses in the above mentioned services.
The process of how to install Mission-Control and how add bucket licenses to it can be found here.
