Synchronous (dependent) is sequential and happens one at a time, whereas in Asynchronous (independent) concurrent parallel operations are possible. In the below reference, total time taken to complete all 4 tasks in Asynchronous system is just 20 seconds compared to that of 45 seconds in the Synchronous sequential process execution. For instance, zoom meetings happens sequential, which is Synchronous, whereas email communication, online posts can be asynchronous, and be concurrent to keep the target audience engaged for different roles, functions, regions, and programs. As referred in the above example, request stacks in synchronous system, and typically referring from a web service request scenario, clients have to wait on the queue until the previous loop is executed and most of the time, what they see is a timeout response. Asynchronous system allows multi-tasking, has better resource utilization, with fewer wait times and is more adaptable and the leading contribution is the enhanced throughput that we get out of asynchronous systems, on the contrary synchronous system performs function one at a time and follows rigid sequence. Thus, it is advantageous to use the asynchronous system, especially in an agile, multi-request system environment, however, it is wise to use synchronous in reactive systems. So to conclude, It is better and suggested to evaluate and identify the dependencies in the processes to select the best optimal approach that works for the organization.
