In all of the descriptions I've found on the subject of Dynamics 365 for Operations on-premise (Local Business Data), they have described that the application servers and databases remain on premise under your care and that there is no sync of data to the cloud, but also that the features to monitor and manage the deployment of your D365 installation can only be done through the cloud through Lifecycle Services.
My question is, does that mean that one is REQUIRED to have a connection to the cloud for LCS or do you have the option to simply not use LCS, or to use LCS without having an actual connection to your running instance?
And if that is the case (that your running instance of D365 is NOT connected to the Internet) what specific functionality does one lose or not have available as a result of not using LCS?
Thanks in advance.
