Logstash can be quite memory intensive and managing the number of workers is easier with a single instance.  
You're better off running multiple pipelines in a single logstash instance. However, if you want to run a containerized/kubernetes version of logstash then you have the advantage of load balancing and high uptime availability.

What do you mean for workers? The nodes of logstash?

No a worker is a thread inside of logstash that can be defined for each pipeline.
