The embodiments herein are directed to collecting information from multiple sources about platform capabilities and evaluating the platform capabilities of at least a requesting computer system and a server. A portal can automatically and dynamically select a proper client/application to handle communication based on availability, connectivity and more characteristics and provide a communication recommendation when requesting a function. Logic in the portal allows the portal to determine how best to set up execution of the function. The portal logic can essentially evaluate all of the options available and then choose the best option.
