An instance limit sets how many concurrent instances of an Asset that can be provisioned. This can be used to manage usage of an Asset that is constrained due to licensing considerations or physical resources. Once a instance limit is reached, the deployment runs will remain in the scheduled state until the resource becomes available (i.e another deployment run that uses the resource is released or cancelled).
Instance limits are defined for software assets, physical machines (containers), and devices. Instances limits can also be set to unlimited. You can set the limit in the UI by selecting the corresponding button on the Asset's main page. You can also set the instance limit in the asset.properties file of a software asset before uploading into CONS3RT.
