What are the two main scaling options available on Mule runtime?

Vertical and horizontal scaling are indeed the two main options available on Mule runtime. Vertical scaling, also known as "scaling up," involves increasing the capacity of an individual server or instance by adding more resources, such as CPU and memory. This approach can improve performance by enabling a single instance to handle more transactions or workloads efficiently.

On the other hand, horizontal scaling, also known as "scaling out," involves adding more servers or instances to distribute the load. This method allows for better fault tolerance and load balancing since multiple instances can share the workload. Horizontal scaling is particularly beneficial in cloud environments, where it is relatively easy to spin up additional instances to handle increased demands.

Together, these scaling strategies provide flexibility in managing applications and services running on Mule runtime, allowing businesses to optimize performance based on their specific needs and growth patterns.
