We enjoy the fast deployment. Cloud Foundry builds the runtime environment directly without requiring dependency management from the developer or administrator.

The autoscaling is great. It is just a switch that needs to be turned on, and autoscaling starts working. At this moment, you begin to see different meters about usage that helps you in updating the scaling limits, which help you tune the running instances. Besides this, autoscaling can be scheduled, so in times of low activity, you can have lower limits or increase in advance for special dates. 

It has good logging. CF has logging events that help identify when a transaction runs and its response time which helps in monitoring execution. 

The ability to focus on the application and service by working around and by passing the technology stack.

Node.js is the most important advantage as it provided us with the ability to start rapidly using a pre-built solution instead of having to deploy from scratch and install a lot of prerequisites.

My favorite component of IBM's solution is Node-RED, which greatly shortens the amount of time required to develop, test, and deploy new applications.
