What is horizontal scaling in CloudHub?

• A. The Mule application can be automatically deployed to multiple CloudHub workers
• B. A Mule application can have its worker resized to a larger or smaller vCore size
• C. It refers to adding more RAM to a single machine
• D. It means increasing the number of CPUs in a data center

Answer: (A)

Horizontal scaling means expanding capacity by running more worker instances to share the workload. In CloudHub, this is achieved by deploying the Mule application to multiple workers, so requests are handled in parallel across those workers. This approach increases throughput and resilience because more workers can process simultaneous traffic, and if one worker goes down, others keep serving requests. This is different from vertical scaling, which adds resources to a single machine (more vCore, RAM, or CPUs). So, deploying to multiple CloudHub workers best captures horizontal scaling.
