Embodiments described herein provide methods and apparatuses for relate to methods and apparatuses for providing processing functions by microservices in a service. A first microservice is capable of providing a first processing function in a service comprising a plurality of microservices. The method includes receiving a processing request to provide the first processing function; obtaining a sequence of a plurality of microservices associated with the processing request, wherein the sequence comprises the first microservice; obtaining a current latency requirement associated with the remaining microservices in the sequence; obtaining an estimated latency associated with the remaining microservices in the sequence; and placing the processing request in a processing queue based on a comparison between the current latency requirement and the estimated latency.
