Defining Multiple Web-Type Dyno Managers (Autoscalers)
While it is possible to define multiple Dyno Managers (Autoscalers) for Web-type Dynos, we strongly advise against it. Dyno Managers operate independently, and having more than one Dyno Manager autoscale the same Dyno Type can lead to conflicts.
However, you can define an additional Web Dyno Manager if you wish to experiment with a different autoscaling strategy or set of rules, while preserving your current setup and maintaining the ability to roll back to it. Just ensure that only one of these Dyno Managers is enabled at any given time.
