What is a limitation of the 3CX Instance Manager concerning instance configurations?

The limitation of the 3CX Instance Manager concerning instance configurations is that it does not support high availability configurations. In environments where uptime and reliability are critical, high availability ensures that if one instance or server fails, another can take over seamlessly without causing disruption to services. The 3CX Instance Manager’s lack of support for this feature means that administrators may need to implement alternative solutions or configurations to achieve redundancy and fault tolerance, which is essential for business continuity.

The other options present challenges or constraints that do not specifically relate to the core configuration capabilities of the Instance Manager. For example, only supporting two instances may suggest restrictions in scalability, yet the 3CX Instance Manager can handle more than two instances depending on the setup. Similarly, user-friendliness is subjective and can vary based on user experience. The need for a continuous internet connection, while relevant for cloud-based applications, is not a direct limitation of how instance configurations are managed within the 3CX Instance Manager itself. Thus, the primary limitation about configuration flexibility remains the absence of high availability support.
