Scalability is defined as the capability to increase hardware or software resources of an application in order to bring about an increase in its performance capacity.
SharePointLMS can support various server configurations. What server configuration you choose typically depends on available administrative or budgetary resources.
A commonly implemented configuration would comprise dedicated servers for both the web server and database server. For greater scalability support, load balancing across a server cluster should be implemented.
In general, SharePointLMS can be adapted to work within most Microsoft technology-based solutions.
