Cloudyn’s EC2 and RDS reserved instance buying recommendation results list the RI’s that will deliver the greatest savings based on the past month’s usage level. This is almost always through all upfront RI’s.
However, many customers prefer partial or no upfront RI’s which reduce the initial capital required at the purchase date. In the Extended Filters section of the RI recommendations report, you can now select the offering type of either all/partial/no upfront. Recommendations results with then contain the purchase price and potentials savings of the selected offering type.
