Multiple typologies : does it make sense?

Hi everyone,
In batch processing, as an example Mapreduce running in datacenters serves more than job and there are a lot of research about the optimization as how to speed up or jobs finishing time, ..etc?
The question:Is the real-time engines (like storm) designed to run more than job (topology) in parallel as Mapreduce, Is it there any business case or research article illustrates the feasibility of running more than one job over storm cluster? 

Thanks and Regards--
