Hi,
for better understanding let me present a scenario;
Background: We have on premises farm SharePoint 2013 deployment we are in transition and migrating our data to new platform.
Scenario: We have a team that will be responsible for SharePoint 2013 app development is there a mechanism where we can restrict an app to be installed on just one site. can we restrict apps to be installed on some specific sites. I have tried to search this scenario but i could not find any definite answer. please also guide me to relevant study material for detailed study.
