What are VM units and how do they work?
Junosphere is ordered and consumed based on the concept of a virtual machine unit (VM unit). VM units are purchased in increments of 10. A single VM unit allows you to run the basic images available within Junosphere—including the VJX Series, Junos Space, and all partner images—for a period of 24 hours. More advanced images may require using more than one VM unit. Ordering a quantity of one gives you access to 10 VM units. After 24 hours, the spent capacity is removed from your bank. For instance, if you have 10 VM units in your bank and you started a topology consisting of a single virtual device, after 24 hours you would be left with 10 – 1 = 9 VM units in your bank.
