+title: Scheduling and Triggering Task Execution
+---
+
+ In ClearML, tasks can be scheduled and triggered automatically, enabling seamless workflow automation. This section 
+ provides an overview of the mechanisms available for managing task scheduling and event-based 
+ triggering.
+
+## Task Scheduling 
+Task scheduling allows users to define one-shot or periodic executions at specified times and intervals. This 
+is useful for:
+
+* Running routine operations such as periodic model training, evaluation jobs, backups, and reports.
+* Automating data ingestion and preprocessing workflows.
+* Ensuring regular execution of monitoring and reporting tasks.
+
+ClearML's offers the following scheduling solutions: 
+* [**UI Application**](../webapp/applications/apps_task_scheduler.md) (available under the Enterprise Plan) - The **Task Scheduler** app
+  provides a simple no-code interface for managing task schedules. 
+
+* [**Python Interface**](../references/sdk/scheduler.md) - Use the `TaskScheduler` class to programmatically manage
+  task schedules. 
+  
+## Task Execution Triggering  
+
+ClearML's trigger manager enables you to automate task execution based on event occurence in the ClearML system, such as:
+* Changes in task status (e.g. running, completed, etc.)
+* Publication, archiving, or tagging of tasks, models, or datasets
+* Task metrics crossing predefined thresholds
+
+This is useful for:
+* Triggering a training task when a dataset has been tagged as `latest` or any other tag
+* Running an inference task when a model has been published 
+* Retraining a model when accuracy falls below a certain threshold
+* And more 
+
+ClearML's offers the following trigger management solutions: 
+* [**UI Application**](../webapp/applications/apps_trigger_manager.md) (available under the Enterprise Plan) - The **Trigger Manager** app
+  provides a simple no-code interface for managing task triggers .
+* [**Python Interface**](../references/sdk/trigger.md) - Use the `TriggerScheduler` class to programmatically manage
+  task triggers.
