I am using Heat Autoscaling in my environment. Can be able to see that it is working fine in case of scale up (Technically scale out) , that is adding a instance based on the load as well as deleting a instance is working fine as expected.

But I need to do scaling (Technically Scale Up) a resource once the load limit is reached.

That is Once the load limit which we mentioned is reached I need to scale the cpu resource that is changing the flavor of the instance.

Anyone please let me know how we can achieve it.

Any help is appreciable.
