Various approaches for allocating resources to an application having multiple application components, with at least one executing one or more functions, in a serverless service architecture include identifying multiple routing paths, each routing path being associated with a same function service provided by one or more containers or serverless execution entities; determining traffic information on each routing path and/or a cost, a response time and/or a capacity associated with the container or serverless execution entity on each routing path; selecting one of the routing paths and its associated container or serverless execution entity; and causing a computational user of the application to access the container or serverless execution entity on the selected routing path and executing the function(s) thereon.
