- <div>
- You can place the upward limit to the number of EC2 instances that Jenkins may launch.
- This is useful for avoiding surprises in the billing statement.
- <P>
- For example, if this field is 3, Jenkins will only launch a new instance
- as long as total number of instances you run on EC2 (regardless of whether that is
- for Jenkins or for other purposes) doesn't exceed this number. In this way,
- even in the worst case of Jenkins starting instances and forgetting about them,
- you have an upper bound in the number of instances that are concurrently executed.
- <p>
- Leave this field empty to remove a cap
- (note that EC2 appears to have its own instance cap at 20.)
