How many Mule applications can run on a CloudHub Worker?

The correct answer is that a CloudHub Worker can run at most one Mule application. In the context of MuleSoft's CloudHub, each worker is designed to host a single application, providing dedicated resources for that specific application. This isolation ensures that the application operates within a stable environment without interference from other applications, which can enhance performance and simplify troubleshooting.

This architecture allows for better resource management and ensures that the resources allocated to the worker are fully utilized by the single application it hosts. Therefore, while it's possible to scale applications by adding more workers, each worker is strictly limited to executing just one Mule application at a time. Understanding this limitation is important for designing your integrations effectively, especially when considering workload and performance factors.
