• Alternative approach B:
• Original idea A:
– One central service to orchestrate the
workload
– Queue on top of other queues
•
Problems:
– Every client can submit jobs to any

• Problems:
– Non-optimal workload
– Limited scalability
– Rather complex clients
– Single point of failure
– Slow interaction with users
