Myriad provides the capability for fine-grained scaling via the Myriad user interface (UI) or the Myriad REST API. Scaling allows is done by using the flexup and flexdown feature. Flexup expands the cluster and flexdown shrinks the cluster. While doing so, the number of instances and size of the scale are specified.  The instance size is a profile parameter that is a predefined value of zero, small, medium, and large. During initial startup, the profile parameter is set to zero, that is, the cluster is launched with zero (0) cpu and zero (0) memory.

Myriad launches the NodeManager instance with a profile of medium.
