Can all components of Apty Client be installed on one server?

Yes, while deploying the system in the On-Premise model. This type of implementation allows companies to keep all their Apty Client content and data behind their firewall. In this case both the Admin console and Apty Client Content/Data stored in the database of a customer’s choice are hosted on the physical server of the customer in one of their own facilities.
