* Enhance availability by proactively augmenting your fleet with a new Spot instance from an optimal pool, before a running instance is interrupted by EC2, by enabling [capacity rebalance](https://docs.aws.amazon.com/autoscaling/ec2/userguide/capacity-rebalance.html).
* Reduce probability of [InsufficientInstanceCapacity](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/troubleshooting-launch.html#troubleshooting-launch-capacity) exceptions with flexible instance configuration.

Using one or more parameters in the table below will automatically create Server Groups with the instance diversification configuration specified, and will use AWS defaults for the parameters not specified.
Using one or more parameters in the table below will automatically create Server Groups with instances distribution configuration specified, and will use AWS defaults for the parameters not specified.
Note that a number of these parameters complement each other. So, combining them can greatly enhance your AWS experience.
