Reserved Instance (RI)

Reserved Instance (RI) is a reservation of cloud resources and capacity purchased at a set price for a given time period. Unlike on-demand pricing, when you purchase a reservation, you commit to paying for all of the hours of the contract’s term. As a benefit, the hourly rate is lowered significantly. 

Turbonomic can help determine how many RI’s to purchase, if any. It can also optimize utilization of the RI inventory, assuring the best RI coverage and a good return on your RI investment.

Pricing is determined by the specific cloud provider. Cloud providers use their own factors to measure RI capacity so you can combine that capacity for different template families. See Normalized Factor Unit (nfu) and RI Ratio
