+| Limit | Value | Description |
+|--|--|--|
+| Actions per experiment | 9 | The maximum number of actions (such as faults or time delays) in an experiment. |
+| Branches per experiment | 9 | The maximum number of parallel tracks that can execute within an experiment. |
+| Steps per experiment | 4 | The maximum number of steps that execute in series within an experiment. |
+| Action duration (hours) | 12 | The maximum time duration of an individual action. |
+| Concurrent experiments executing per region and subscription | 5 | The number of experiments that can run at the same time within a region and subscription. |
+| Total experiment duration (hours) | 12 | The maximum duration of an individual experiment, including all actions. |
+| Experiment history retention time (days) | 120 | The time period after which individual results of experiment executions are automatically removed. |
+| Number of experiment resources per region and subscription | 500 | The maximum number of experiment resources a subscription can store in a given region. |
+| Number of targets per action | 50 | The maximum number of resources an individual action can target for execution. For example, the maximum Virtual Machines that can be shut down by a single Virtual Machine Shutdown fault. |
+| Number of agents per target | 1,000 | The maximum number of running that can be associated with a single target. For example, the agents running on all instances within a single Virtual Machine Scale Set. |
+| Number of targets per region and subscription | 10,000 | The maximum number of target resources within a single subscription and region. |
