- Vertical Scalability
- There are no built-in limits as to the overall number of jobs and number of parallel job executions per Controller and Agent.
- A single Controller is tested for some 50 000 parallel tasks, a single Agent is tested for approx. 15 000 parallel tasks.
- Adding more power to a single machine (CPU, Memory, SSD Disks) will improve performance as the components will make use of all available cores.
- Horizontal Scalability
- Splitting the job load across a number of Agents will push the number of parallel tasks.
...
- The following indicators should be considered:
- The overall number of workflows and jobs that will be available.
- The number of jobs that will be executed in parallel.
- Number of Jobs
- Small environments are assumed to use < 1 000 jobs, medium sized environments use < 20 000 jobs, larger environments use larger numbers.
- Parallelism of Jobs
- Small environments run < 100 parallel jobs, medium sized environments run < 1 000 parallel jobs, larger environments run larger numbers of jobs.
Basic Recommendation
The recommendation indicates dedicated resources available to JS7 components. Resource usage by additional components running on a machine come on top.
