Target Architecture
Components
Cockpit
- manage job configuration, optionally with a repository service
- manage release procedure for job configuration to Master
- accept job events and job history from Master
- report job events to event queue
- report job history to reporting database
- run authentication and authorization service
- run web server and web services
- run JobScheduler Controller Web GUI
- bundle a number of Masters and delegate commands to Master
Master
- control the job plan (calendar), what to run, when and where
- forward daily plan to Autonomous Agent Cluster
- accept task execution result, job history and log information from Agents
- optionally operate in an active-passive cluster
Autonomous Agent
- implement a fault-tolerant peer-to-peer network of Agents
- accept daily plan from Master
- available for active-passive and active-active clustering:
- fixed priority scheduling
- round-robin scheduling
- execute job chains independently from Master availability
- resolve more complex dependencies with Master, e.g. for checks of the job history or of external events from other machines
- report job history and log information back to Master
- run distributed recovery files for recovery purposes
- allow access by a number of Master instances
- provide resilience features for reconciliation after Master connection loss
