How does Runtime Fabric relate to multiple Mule runtime versions?

Runtime Fabric is designed to provide flexibility and scalability in deploying Mule applications by allowing different versions of Mule runtime to coexist within the same fabric. This capability is particularly beneficial for organizations that have applications developed in various Mule versions and require the ability to manage and run them simultaneously without the need for deploying them in isolation. This feature supports a smoother transition when upgrading applications from one version to another, as teams can gradually migrate and test their applications while maintaining operational continuity.

The ability to run multiple versions in the same fabric enhances agility and lets teams leverage the specific features and improvements of newer Mule runtime versions when needed, while still supporting legacy applications. Therefore, this feature of Runtime Fabric is crucial for organizations with diverse integration needs and varied application lifecycles.

Other options, such as restricting to a single version or requiring all runtimes to be dockerized, do not accurately reflect the flexibility provided by Runtime Fabric, nor does the limitation on the number of runtimes align with its design principles aimed at maximizing performance and operational efficiency across different Mule applications.
